Understanding Ibuprofen: A Versatile Over-the-Counter Pain Reliever

Ibuprofen is a widely used over-the-counter (OTC) medication that belongs to the class of drugs known as non-steroidal anti-inflammatory drugs (NSAIDs). It’s primarily used to alleviate minor aches and pains while also reducing fever. Available in both OTC and prescription strengths, ibuprofen has become a go-to solution for many seeking relief from various discomforts.

How does ibuprofen work in the body. Ibuprofen functions by inhibiting the production of prostaglandins, compounds responsible for pain, inflammation, and fever. By reducing prostaglandin levels, ibuprofen effectively mitigates these symptoms, providing relief to those experiencing discomfort.

Common Brand Names Containing Ibuprofen

• Advil®
• MOTRIN®
• Various store brands (e.g., Walmart’s “Equate” or CVS Health store brand)

The Many Uses of Ibuprofen: From Headaches to Menstrual Cramps

Ibuprofen’s versatility makes it a popular choice for addressing a wide range of minor ailments. What specific conditions can ibuprofen effectively treat. Here’s a comprehensive list:

• Headaches and migraines
• Toothaches
• Backaches
• Menstrual cramps
• Muscular aches
• Minor arthritis pain
• Common cold symptoms
• Fever reduction

In addition to its standalone use, ibuprofen is often found in combination medicines that target multiple symptoms simultaneously. These may include treatments for allergies, sleeplessness, and various cold and flu symptoms.

Proper Dosage and Administration of Ibuprofen

Adhering to recommended dosages is crucial when using ibuprofen to ensure both safety and efficacy. How much ibuprofen can an adult safely take. The U.S. Food and Drug Administration (FDA) advises that adults should not exceed 1,200 milligrams (mg) of ibuprofen within a 24-hour period.

It’s important to note that different ibuprofen products may have varying strengths. Always read and follow the Drug Facts label on the packaging. Most OTC ibuprofen products caution against using the active ingredient for more than 7-10 consecutive days without consulting a healthcare provider.

Ibuprofen Dosage Guidelines

1. Read the label carefully before use
2. Do not exceed the recommended dose
3. Space doses appropriately throughout the day
4. Avoid using for extended periods without medical advice
5. Consult a healthcare provider if symptoms persist or worsen

Safety Considerations and Precautions When Using Ibuprofen

While ibuprofen is generally safe when used as directed, certain precautions should be taken to minimize potential risks. Who should exercise caution or avoid using ibuprofen. The following groups should consult a healthcare professional before using ibuprofen:

• Individuals already using another NSAID
• Those taking blood thinners, steroids, or diuretics
• Pregnant or breastfeeding women
• Adults over 60 years of age
• People with a history of stomach ulcers or bleeding problems
• Individuals who consume three or more alcoholic drinks daily
• Those under medical care for any serious condition
• People taking aspirin for heart attack or stroke prevention

When is it absolutely necessary to avoid ibuprofen. Ibuprofen should not be used in the following situations:

• Immediately before or after heart surgery
• If you’ve had an allergic reaction to any pain reliever or fever reducer
• During the last trimester of pregnancy (unless specifically advised by a healthcare provider)
• If the product’s tamper-evident packaging is compromised

It’s also important to note that ibuprofen should not be given to children under six months of age without medical supervision.

Recognizing and Managing Potential Side Effects of Ibuprofen

Like all medications, ibuprofen can cause side effects in some individuals. What are the most common side effects associated with ibuprofen use. While many people use ibuprofen without experiencing significant issues, it’s important to be aware of potential adverse reactions:

• Stomach upset or discomfort
• Heartburn
• Nausea
• Headache
• Dizziness
• Mild allergic reactions (e.g., rash, itching)

In rare cases, more serious side effects may occur. When should you seek immediate medical attention while using ibuprofen. Stop use and contact a healthcare provider if you experience:

• Signs of an allergic reaction (hives, facial swelling, difficulty breathing)
• Symptoms of stomach bleeding (feeling faint, vomiting blood, persistent stomach pain)
• Unexplained redness or swelling in the painful area
• Fever lasting more than three days or pain persisting for more than 10 days

Ibuprofen Interactions: Medications and Conditions to Consider

Understanding potential drug interactions is crucial when using ibuprofen. Which medications or conditions may interact with ibuprofen? Several substances and health conditions can affect how ibuprofen works in the body or increase the risk of side effects:

Medications that may interact with ibuprofen:

• Other NSAIDs (e.g., aspirin, naproxen)
• Blood thinners (anticoagulants)
• Corticosteroids
• Diuretics
• Certain antidepressants
• Some blood pressure medications

Health conditions that may be affected by ibuprofen use:

• Stomach ulcers or gastrointestinal bleeding
• Heart disease or high blood pressure
• Kidney disease
• Liver disease
• Asthma
• Bleeding disorders

How can you minimize the risk of interactions when using ibuprofen? Always inform your healthcare provider about all medications, supplements, and health conditions before starting ibuprofen. They can provide personalized advice on potential interactions and help you determine if ibuprofen is the right choice for your situation.

Comparing Ibuprofen to Other Over-the-Counter Pain Relievers

Ibuprofen is one of several OTC pain relievers available to consumers. How does it compare to other common options like acetaminophen and aspirin? Let’s examine the key differences:

Ibuprofen vs. Acetaminophen (Tylenol)

• Both reduce pain and fever, but ibuprofen also reduces inflammation
• Acetaminophen may be preferred for those with stomach sensitivity
• Ibuprofen is often more effective for menstrual cramps and toothaches

Ibuprofen vs. Aspirin

• Both are NSAIDs with similar pain-relieving and anti-inflammatory properties
• Aspirin has additional blood-thinning effects, making it useful for heart health in some cases
• Ibuprofen may be preferred for those with a history of stomach ulcers

Which pain reliever is best for specific situations? The choice depends on individual factors such as the type of pain, underlying health conditions, and potential side effects. Consult a healthcare provider for personalized recommendations.

Special Considerations for Ibuprofen Use in Children and Elderly Adults

While ibuprofen can be effective for both children and older adults, special care must be taken when administering it to these age groups. What precautions should be observed when giving ibuprofen to children or elderly individuals?

Ibuprofen Use in Children

• Always use children’s formulations and follow age-appropriate dosing guidelines
• Avoid use in children under 6 months without medical supervision
• Be cautious if the child is dehydrated or has ongoing vomiting or diarrhea
• Monitor for signs of allergic reactions or stomach upset

Ibuprofen Use in Elderly Adults

• Start with lower doses due to increased risk of side effects
• Be aware of potential interactions with other medications commonly used by older adults
• Monitor kidney function, especially in those with existing kidney issues
• Use caution in individuals with a history of ulcers or gastrointestinal bleeding

How can caregivers ensure safe ibuprofen use in these populations? Regular communication with healthcare providers, careful adherence to dosing instructions, and vigilant monitoring for side effects are key to safe ibuprofen use in children and elderly adults.

Ibuprofen and Pregnancy: Understanding the Risks and Alternatives

The use of ibuprofen during pregnancy requires careful consideration due to potential risks to the developing fetus. What are the current recommendations regarding ibuprofen use during pregnancy?

• Avoid ibuprofen use during the first and second trimesters unless specifically advised by a healthcare provider
• Do not use ibuprofen during the third trimester due to increased risks of complications
• Be aware of the FDA warning about potential kidney problems in unborn babies when NSAIDs are used around 20 weeks of pregnancy or later

What alternatives are available for pain relief during pregnancy? Acetaminophen is generally considered safer for use during pregnancy, but always consult with a healthcare provider before taking any medication while pregnant. They can provide personalized advice based on your specific situation and health history.

Long-Term Ibuprofen Use: Balancing Benefits and Risks

While ibuprofen can be highly effective for short-term pain relief, long-term use may carry additional risks. What are the potential consequences of prolonged ibuprofen use? Regular, extended use of ibuprofen may increase the risk of:

• Gastrointestinal ulcers and bleeding
• Kidney damage
• Increased blood pressure
• Cardiovascular events in susceptible individuals

How can individuals who require ongoing pain management balance the benefits and risks of ibuprofen use? Consider these strategies:

1. Work closely with a healthcare provider to monitor for potential side effects
2. Explore alternative pain management techniques, such as physical therapy or acupuncture
3. Use the lowest effective dose for the shortest duration possible
4. Consider alternating ibuprofen with other pain relief methods to minimize continuous use
5. Discuss the possibility of using topical NSAID formulations to reduce systemic exposure

Remember, chronic pain management often requires a multifaceted approach. A healthcare provider can help develop a comprehensive plan that addresses your pain while minimizing potential risks associated with long-term medication use.

Proper Storage and Disposal of Ibuprofen Products

Ensuring proper storage and disposal of ibuprofen is essential for maintaining its effectiveness and preventing accidental ingestion. How should ibuprofen be stored to maintain its potency and safety?

• Keep ibuprofen in its original container with the label intact
• Store at room temperature, away from heat and moisture
• Keep out of reach of children and pets
• Check expiration dates regularly and dispose of expired products

What is the proper way to dispose of unused or expired ibuprofen? Follow these guidelines:

1. Check for local medication take-back programs in your area
2. If no take-back option is available, mix the medication with an undesirable substance (e.g., used coffee grounds) and place in a sealed container before disposing in household trash
3. Remove or obscure personal information on the empty container before discarding
4. Do not flush ibuprofen down the toilet unless specifically instructed to do so by the medication label

By following proper storage and disposal practices, you can help ensure the safety and efficacy of your ibuprofen products while also protecting the environment and preventing potential misuse.

Uses, Dosage, and Side Effects – KnowYourOTCs

What is ibuprofen?

Ibuprofen is an internal analgesic available in over-the-counter (OTC) medicines that temporarily relieve minor aches and pains and reduce fevers. It is also available in prescription-strength medicines. Ibuprofen is part of a group of pain relievers and fever reducers called non-steroidal anti-inflammatory drugs (NSAIDs).

Ibuprofen can be the only ingredient in oral pain relievers and fever reducers or it can be found in medicines that treat migraines. It is also available in medicines that not only relieve pain or reduce fever, but treat additional symptoms as well, such as occasional sleeplessness, allergies, the multiple symptoms of the common cold, and symptoms associated with menstruation.

The U.S. Food and Drug Administration (FDA) is warning that use of nonsteroidal anti-inflammatory drugs (NSAIDs) around 20 weeks or later in pregnancy may cause rare but serious kidney problems in an unborn baby. Click here to learn more.

What is ibuprofen used to treat?

Temporarily relieves minor aches and pains due to:

Temporarily reduces fever.

Common brands containing ibuprofen:

• Advil^®
• MOTRIN^®
• Store Brands (ex. Walmart’s “Equate” store brand or CVS Health store brand)

How much ibuprofen can you take?

The U.S. Food and Drug Administration (FDA) recommends adults take no more than 1,200 milligrams (mg) of ibuprofen in a 24-hour period.

Different types of products containing ibuprofen have different strengths. That’s why it is always important to read and follow the Drug Facts label. Most medicines warn against use of an active ingredient for longer than 7-10 days. Stop use and ask a doctor if symptoms persist.

Safety guide for ibuprofen

Ibuprofen is approved by the FDA and is safe and effective when used according to the Drug Facts label. You should never take more ibuprofen or for a longer period of time than the label instructs unless your healthcare provider tells you to. Certain health risks such as heart attack, stroke, or stomach bleeding may increase if you use more than directed or for longer than directed.

Ask a healthcare professional before use if:

• You are currently using another medicine containing an NSAID (e.g., aspirin, magnesium salicylate, naproxen sodium, ibuprofen, or ketoprofen).
• You are taking a blood thinner (anticoagulant), steroid, diuretic, or any other drug.
• You are pregnant or breastfeeding. Women in the last three months of pregnancy are specifically told not to use ibuprofen or any NSAID without a healthcare provider’s permission.
• You are over the age of 60.
• You have had stomach ulcers or bleeding problems.
• You drink three or more alcoholic drinks every day.
• You are under a healthcare provider’s care for any serious condition.
• You are taking aspirin for heart attack or stroke. Ibuprofen may decrease this benefit of taking aspirin.
• You are unsure about child dosing instructions. Read the label and contact your healthcare professional as directed.
• Before giving ibuprofen to a child if the child has not been drinking fluids, has lost a lot of fluid due to vomiting or diarrhea, or is taking a diuretic.

Do not use if:

• You are preparing to have heart surgery or if you just had heart surgery.
• You have ever had an allergic reaction to any other pain reliever or fever reducer.
• You are a woman in the last three months of pregnancy, unless your healthcare professional specifically tells you to. Problems in the unborn child or complications during delivery could occur.
• Tamper-evident packaging features such as seals, locks, and films are not clear or seem broken.
• Do not give ibuprofen to children under six months of age.

Stop use and ask a doctor if:

• An allergic reaction occurs. Seek medical help right away.
• Your fever gets worse or lasts more than three days, or if your pain gets worse and lasts more than 10 days.
• You have signs of stomach bleeding, such as if you feel faint, vomit blood, have stomach pain or upset that lasts or does not get better, or have bloody or black stools.
• Redness or swelling is present in the painful area or if any new symptoms appear.
• You take too much. Immediately contact a healthcare provider or the poison control national helpline at 800.222.1222.
• If your child has a severe sore throat that lasts for more than two days, or is accompanied or followed by high fever, headache, nausea, or vomiting.

What are the side effects of ibuprofen?

• Ibuprofen, like other NSAIDs, may cause a severe allergic reaction, especially in people allergic to aspirin. Symptoms may include hives, facial swelling, asthma (wheezing), shock, skin reddening, rash, or blisters.
• Severe stomach bleeding may occur. The chance is higher if you are age 60 or older; have had stomach ulcers or bleeding problems; or if you are taking a blood thinner (anticoagulant), steroid drug, or other medicines containing NSAIDs (e.g., aspirin, magnesium salicylate, naproxen sodium, ibuprofen, or ketoprofen).
• If upset stomach occurs, you may take the medicine with milk or food.

FDA approves combination ibuprofen-acetaminophen drug for U.S.

March 02, 2020

The Food and Drug Administration has approved the first over-the-counter ibuprofen and acetaminophen combination drug for the U.S.

The product — called Advil Dual Action — will be available nationwide later in 2020 and contains 250 mg of ibuprofen and 500 mg of acetaminophen, said GlaxoSmithKline, the drug’s manufacturer, in a news release.

The ADA has long advocated for the development of a single strength-controlled acetaminophen-ibuprofen combination drug to be available over-the-counter for dental patients — particularly as the nation continues to battle the opioid epidemic.

Dr. Mia Geisinger, chair, ADA Council on Scientific Affairs, cheered the news and pointed to the ADA Science Institute’s 2018 overview of systematic reviews of acute pain medications that concluded combinations of ibuprofen and acetaminophen “offered the most favorable balance between benefits and harms” for treating dental pain.

“Many other studies point to using nonsteroidal medications with or without acetaminophen as being safe, effective and a preferred alternative to opioid medications in most patients,” said Dr. Geisinger, who also cited studies led by past and present CSA members published in the Journal of the American Dental Association. “The introduction of this medication may simplify this medication protocol for use in dental practice and further reduce the use of opioid prescriptions as first-line pain control therapy.”

The approval was based on data from several clinical studies, including three efficacy and safety trials, for the product, according to GlaxoSmithKline. The company also noted the data demonstrated “a fixed-dose combination of ibuprofen and acetaminophen achieves a superior level of pain relief compared to the individual components alone.”

“For decades, many consumers have been using ibuprofen and acetaminophen to get the benefits of both active ingredients when safely treating their headaches, muscle aches, backaches, arthritis and other joint pain,” said Franck Riot, head of research and development, GlaxoSmithKline, Consumer Healthcare. “[Advil Dual Action] will offer U.S. consumers the first-ever alternative option – a single, fixed-dose combination pain reliever.”

For information about the ADA’s advocacy efforts with opioids education, visit ADA.org/opioids. Additional online resources can be found on the ADA Center for Professional Success. The ADA Catalog also features “The ADA Practical Guide to Substance Use Disorders and Safe Prescribing.”

Advil or Motrin (ibuprofen) – Dr. Adam Stewart

“Advil” is a brand name for the drug, “ibuprofen“. It also the same drug as “Motrin“. All of these are the same medication, just different names.

Advil is an ANTI-INFLAMMATORY. It is commonly used to treat pain, inflammation, or fever. Other examples of anti-inflammatory medications are: “Naproxen,” “Aleve,” “Celebrex,” “Arthrotec,” or “Meloxicam.”

Never take more than one type of anti-inflammatory in the same day. (However, Tylenol is different. Tylenol is not an anti-inflammatory, so you can take Tylenol in addition to Advil or other anti-inflammatory medications.)

You should avoid Advil (and other anti-inflammatory medications) if you have kidney problems, bleeding from your stomach or bowels, or if you are taking certain blood pressure medications.

FOR ADULTS:

Advil usually comes in a 200mg pill (Regular Strength), or a 400mg pill (Extra Strength). You can also find equivalent non-brandname versions of ibuprofen that are usually less expensive.

Adults can take up to 600mg of Advil every 6 hours, as needed:

• i.e. take THREE regular strength 200mg pills every 6 hours.
• or, 1 and 1/2 extra strength 400mg tablets every 6 hours.

Alternatively, you may wish to take 400mg every 4 hours, as needed:

• i.e. take TWO regular strength 200mg pills every 4 hours.

FOR CHILDREN:

Children’s doses are based on their weight. Be sure you know your child’s weight.

Children’s Advil comes in many different strengths and forms. Be sure you look on the bottle to know what form you are using. The most common forms are:

“PEDIATRIC Drops” – contains 200mg of Advil per 5ml.

“CHILDREN’s suspension” – contains 100mg of Advil per 5ml

“JUNIOR STRENGTH Tablets” – contain 100mg of Advil per tablet.

The doses recommended on the bottles are usually less than your child can actually take.

THE PROPER DOSE FOR ADVIL IN CHILDREN IS:

• 10mg per kilogram body weight every 6 hours as needed.
• Up to a maximum of 600mg per dose.

Uses, Complications, Recalls and Warnings

Tylenol (acetaminophen) is the most popular over-the-counter (OTC) pain relief medication used in the U.S. and around the world. Acetaminophen is the active ingredient in Tylenol and the generic name of the drug that is commonly found in other medications.

The drug was first sold in 1955 as Tylenol Elixir for Children, and today millions of American adults and children use the drug every week for common ailments such as head and body aches, colds, and fevers. In fact, according to the Consumer Healthcare Products Association, about 52 million consumers in the U.S. use products containing Tylenol each week.

Manufactured by Johnson & Johnson subsidiary McNeil Laboratories, the drug generates more than $1 billion a year. It is marketed as an effective painkiller that is safer than non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen, which are associated with stomach discomfort or bleeding.

Tylenol Uses

Tylenol belongs to a class of drugs called analgesics and antipyretic agents. An analgesic relieves pain. An antipyretic reduces fevers. For more than 50 years, doctors have recommended Tylenol for both uses.

Unlike other analgesics like aspirin and ibuprofen (Advil, Motrin), Tylenol does not treat inflammation. It is most effective for minor aches and pains but can be used safely for long-term chronic pain such as arthritis. In fact, the American College of Rheumatology recommends Tylenol to treat arthritis, and it is especially useful in types of arthritis that are not accompanied by inflammation, like osteoarthritis.

How Tylenol Works

Researchers don’t fully understand how Tylenol works. Although there are several theories, none seems to satisfy everyone.

One theory is that Tylenol controls fever and pain by blocking an enzyme called cyclooxygenase (COX-1). COX sends out chemicals known as prostaglandins that make the body feel pain and induce fever in response to an injury or illness. If this theory is correct, then Tylenol works very similarly to aspirin, ibuprofen, and other NSAIDs.

Some researchers believe Tylenol works on the endocannabinoid system, which plays a part in the sensation of pain in the body. The main ingredient in marijuana, THC, also works through this system, which explains why some people look to marijuana for a form of pain relief.

A third theory is that Tylenol may also alter signaling from the neurotransmitter serotonin. Other researchers believe the drug’s effectiveness stems from the fact it inhibits neurotransmitter receptors in the brain that register pain, such as N-methyl-D-aspartate and substance P.

Still, other researchers say Tylenol may work through a combination of all of these theories. And if you ask Johnson & Johnson: “It works by elevating the body’s overall pain threshold so you feel less pain, and lowers your fever by helping your body eliminate excess heat.”

Common Side Effects of Tylenol

Tylenol on its own is a non-prescription (over-the-counter) medication. While prescription medications are required to include certain prescribing information, such as common side effects, non-prescription medications like Tylenol do not typically contain the same information. Therefore, much of the information regarding side effects provided for over-the-counter Tylenol medications refers to serious side effects of the drug, usually due to overdose.

Common Side Effects of Acetaminophen Include:

• Constipation (infrequent or difficult to pass bowel movements)
• Agitation
• Headaches
• Insomnia (trouble falling asleep or staying asleep)
• Vomiting

Complications Associated with Tylenol

Tylenol is associated with serious complications, including liver damage and rare but dangerous skin reactions. It is the leading cause of acute liver failure in the U.S., and the drug in some cases has led to fatalities. The active ingredient in Tylenol, acetaminophen, accounts for more than 100,000 calls to poison centers, roughly 60,000 emergency-room visits and hundreds of deaths each year in the U.S. In England, it is the leading cause of liver failure requiring transplants.

“Acetaminophen is a dangerous drug,” Dr. John Brems, professor of surgery and chief of intra-abdominal transplantation at Loyola University in Chicago told ABC News. “Many of these patients took acetaminophen in addition to alcohol. I end up transplanting three to four patients per year, and two to three die before we can transplant them. It is probably the most dangerous OTC drug in this country.”

Timeline of FDA Tylenol Actions:

• 2009

  FDA issued guidelines for adding overdose information to products.

• 2011

  The agency confirmed the link between acetaminophen and liver damage and added a black box warning, the agency’s strongest warning, to the label of prescription products containing the drug.

• 2011
  FDA asked drug manufacturers to limit the strength of acetaminophen in prescription drug products to 325 mg.
• 2011

  The agency added a warning highlighting the potential for allergic reactions (e.g., swelling of the face, mouth, and throat, difficulty breathing, itching, or rash) to the label of all prescription drug products that contain acetaminophen.

• 2013

  FDA released a safety warning about acetaminophen and rare but serious skin reactions.

• 2014

  The agency announced its intent to take steps to withdraw approval of prescription combination drug products containing more than 325 mg of acetaminophen.

• 2015

  FDA announces findings from review of acetaminophen use during pregnancy.

Tylenol Use During Pregnancy

The FDA reviewed possible risks of acetaminophen use during pregnancy and released its findings in a January 2015 Drug Safety Communication.

According to the safety communication, two U.S. studies indicate that 65 to 70 percent of pregnant women in the U.S. reported using acetaminophen anytime during pregnancy.

One study reported an increased risk between acetaminophen use in pregnancy and attention deficit hyperactivity disorder (ADHD) in children. Women reporting any acetaminophen use in pregnancy were also significantly more likely to have a child with a hyperkinetic disorder (HKD) diagnosis or a child who used ADHD medications, compared to unexposed women.

“Associations for all outcomes were strongest for acetaminophen use in multiple trimesters and for more than 20 weeks during pregnancy,” the FDA noted.

The FDA said the study “had a number of methodologic limitations” and concluded “the weight of evidence is inconclusive regarding a possible connection between acetaminophen use in pregnancy and ADHD in children.”

Tylenol Recalls

Tylenol faced a string of recalls from 2009 to 2012. Some Tylenol products didn’t return to store shelves until 2013.

In 2009, McNeil recalled many Tylenol brands because a chemical for treating wood made it into the medicine, causing nausea, vomiting and diarrhea. In 2011, it expanded the recall to include several more lots of the medication. The recall involved tens of thousands of Tylenol products and prompted Johnson & Johnson to close a manufacturing plant. Furthermore, the FDA stepped in to supervise quality control measures at three plants. Then in 2012, McNeil recalled nearly 600,000 bottles of infant Tylenol for faulty dosing systems that could result in babies receiving too little or too much medicine.

Chicago Tylenol Murders

The drug was also linked to several murders in 1982 called the Chicago Tylenol Murders. Several people in Chicago died after taking Extra-Strength Tylenol caplets that were laced with cyanide. McNeil was not implicated in the murders because the bottles came from different factories, and all seven deaths took place in the Chicago area, ruling out the possibility of tampering during production.

After the murders, Johnson & Johnson sent warnings to hospitals and distributors, stopped all advertising and producing Tylenol and recalled approximately 31 million bottles. The murders remain unsolved.

Other Examples of Tylenol Recalls

Tylenol Forms and Doses

Tylenol is available in tablet, chewable tablet, capsule, suspension or solution (liquid), extended-release (long-acting) tablet and orally disintegrating tablet forms and as a suppository for rectal use. There is also an intravenous form of acetaminophen that is used in the hospital setting.

Most formulations are available in several dose amounts, usually from 300 mg to 1000 mg. People can obtain it in prescription and non-prescription strengths; however, the strength of acetaminophen in prescription drug products is limited to 325 mg per request by the FDA.

The maximum indicated dose in a 24-hour period should not exceed 4,000 mg for most patients. Taking more than 4,000 mg of Tylenol a day puts users at risk for liver failure. Experts say anyone taking Tylenol long-term for chronic pain should consider having liver function tests done once or twice a year.

Taking Tylenol

Users do not need to take Tylenol with food or on a full stomach. Don’t take acetaminophen if you drink three or more alcoholic drinks a day, and don’t take more than one product that contains acetaminophen at a time.

Child-Specific Product

To administer the medicine to children, use the child-specific product with a dosing cup or dropper that comes with it. Teaspoons found in the home vary in size and their use to administer Tylenol could overdose or underdose a child. You may need to shake the liquid before each use.

Chewable Tablet

The Tylenol Meltaways chewable tablet softens in the mouth to make it easier to chew. Chew the tablet thoroughly before swallowing it.

Meltaways

Meltaways are orally disintegrating tablets. Place the tablet in your mouth and either wait for it to dissolve or chew it before swallowing.

Extended–Release Tablets

Extended-release tablets are meant to be swallowed whole. Do not split, chew, crush or dissolve these tablets before swallowing.

Acetaminophen Labels

Because acetaminophen is present in hundreds of medications, it’s important to read the labels of all prescription and OTC drugs to see if they contain it.

Some labels may replace the word acetaminophen with:

• APAP
• 
  AC
• 
  Acetaminoph
• 
  Acetaminop
• 
  Acetamin
• 
  Acetam
• 
  Paracetamol

The FDA, National Council for Prescription Drug Programs (NCPDP) and pharmacies across the nation are working to ensure “acetaminophen” is fully spelled out on prescription labels. NCPDP estimates that more than 75 percent of pharmacies in the U.S. are part of this effort.

Chronic Pain Medications: Anti-Depressants to Opioids

Pain is our body’s way of warning us that something may be wrong. It’s very important to “listen” to our bodies when you don’t feel right because pain that isn’t treated can become chronic and negatively-impact your health. From OTC meds such as acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) to opioids and other prescription drug options, here’s what to know. 

Medications play a crucial role in managing pain but every body is different and responsiveness can vary greatly. Some benefit from OTC or prescription-strength NSAIDs (ibuprofen aka Motrin) while others may need something stronger, such as an opioid.

Acute Versus Chronic Pain

Pain is classified in two ways. It’s either acute or chronic. Acute pain begins suddenly and feels sharp. It may be caused by broken bones or cuts. It usually resolves right away or may last up to three months.

Sometimes acute pain transitions to chronic pain. This may happen when the physical condition causing the pain is unresolved such as cancer or arthritis. It can also happen if the nervous system gets impaired and sends pain signals when there isn’t a specific cause of pain. 

Chronic pain is ongoing pain that lasts for more than three months and is usually harder to daignose. It’s important to distinguish between acute and chronic pain as treatment choices differ. Over-the-counter (OTC) medications, such as aspirin, acetaminophen, or ibuprofen (an NSAID), may not be strong enough. In fact, most chronic pain patients need prescription medications to cope with pain.

Non-Opioid Options for Pain

Although there are many types and brands of medications, what medication your doctor recommends depends on you—your pain level, treatment goals, and overall health.

Our  Smart Patient’s Guide (below) can be printed and gives a  more detailed look at some of the non-opioid medications—NSAIDS, antidepressants, and more—that can be used to  for managing a variety of chronic pain conditions.

Before taking any medication, even if it’s an over-the-counter medication, discuss it with your doctor. Some medications have serious side effects if they’re not taken as directed. Your doctor should be aware of everything you’re taking, including herbal remedies and supplements, because of possible drug interactions or side effects.

How to Explain Your Pain

Now that you know the difference between acute and chronic pain, lets drill down a bit more. The cause of your pain will for the most part determine the type of pain you are experiencing. Describing your symptoms accurately is important because it helps your healthcare provider choose the best treatment for your pain.

Nociceptive pain and neuropathic pain are the two most common types of pain.

Nociceptive Pain

Nociceptive pain is caused by tissue damage or injury to the skin, bones, muscles, or joints. Think broken arm, sprained ankle, a puncture wound from a dog bite, or a banged-up knee.

Treatment for nociceptive pain may range from mild OTC meds such as Advil to powerful prescription drugs like Percocet.

Treating Nociceptive Pain with NSAIDs

Most doctors will start with an NSAID for pain. NSAIDs are divided in two categories: COX-1 inhibitors and COX-2 inhibitors. COX-1 inhibitors include medications like ibuprofen (Advil, Motrin) and naproxen (Aleve). This class can be harsh on the stomach and may cause ulcers or bleeds, so taking it with food is a good idea.

If you experience black or tarry stools, bright red blood in vomit, or severe cramps,  seek medical attention immediately as these symptoms indicate a stomach bleed. These reactions can occur at any time during use and without warning symptoms.

COX-2 inhibitors are easier on the stomace and include medications like celecoxib (Celebrex) and meloxicam (Mobic). The bad news is they may increase the risk of heart attack or stroke so be sure to discuss with your doctor.

If pain exists in just one area of your body, such as arm or leg, consider treating it with a topical NSAID such as diclofenac (Voltaren gel). Voltaren gel must be applied to clean, dry, and intact skin

Acetaminophen (Tylenol) can also be used but the daily dose should not exceed 4 grams to avoid liver damage. Keep in mind that acetaminophen may be contained in other prescription medications as well as OTC medications.

Let your doctor know about all the medications you are taking, including herbal remedies and supplements, to avoid any drug interactions or toxicities. 

Treating Nociceptive Pain with Opioids  

If the pain is still not adequately controlled, opioid therapy (for a limited period) may be recommended until the pain is controlled. Prolonged use of opioids is ill advised due to the many health risks associated with them.

Sadly, the long-term use of opioids increased significantly—despite the numerous serious risks associated with them—during the past few years.

In 2017, more than 191 million opioid prescriptions were dispensed to Americans—with wide variation across states. To avoid unnecessary risks without a justified benefit, it is important for that you and your doctor establish pain goals. For example, experiencing less pain rather than NO pain may be a reasonable goal to set. 

What Are Opioids?

Opioids are sometimes referred to as narcotics. They are stong painkillers derived from the opium poppy plant and are used to block pain signals between the brain and the body. Opioids are sometimes prescribed to alleviate moderate to severe acute pain and chronic pain.

Opioids provide immediate relief to intense pain by changing your brain’s perception of the pain message but other medication options are typically attempted to treat the pain first. They may be prescribed for low back pain, neuropathic pain, or arthritis pain. 

Because of the risk of addiction, abuse, or misuse, opioid use must be closely monitored by your doctor and should not be used regularly.

Examples of opioids include hydrocodone, hydromorphone, methadone, fentanyl, meperidine, morphine, tramadol, and oxycodone. The most common drugs involved in prescription opioid overdose deaths include methadone, oxycodone, and hydrocodone.

Respiratory depression is one of the most dangerous risks associated with opioids. All opioids slow down breathing, and in severe cases can cause the breathing to completely stop. The risk is higher if you have underlying breathing conditions such as asthma or sleep apnea.

If you have liver or kidney disease, opioids can build up in your body and put you at a higher risk for complications. Benzodiazepines (such as Xanax, Ativan) or Z-drugs (such as Ambien) or muscle relaxants (such as Flexeril) can also increase the risk for respiratory depression when used with opioids. 

Constipation is a very common, and very unpleasant, side effect of opioids. Constipation does not resolve with time and requires treatment. Stimulant laxatives such as senna, are the most effective treatment.

Neuropathic Pain

Pain that results from damage to the nerves is known as neuropathic pain. It presents as tingling, numbing, or shooting pain. Some describe it as “pins and needles”.

This type of pain may occur due to poorly-managed diabetes (referred to as diabetic neuropathy), trauma, the aftermath of surgery, infections, chemotherapy, fibromyalgia, or shingles (referred to as postherpetic neuralgia). Neuropathic pain requires a different treatment which may involve antidepressants, anti-seizure drugs, or topicals such as lidocaine and capsaicin. 

Antidepressants for Pain

Not all antidepressants can work for pain. Only antidepressants that affect norepinephrine (adrenaline in the nerves) are found to be effective for chronic pain.

These antidepressants are tricyclic antidepressants (TCAs) and serotonin norepinephrine reuptake inhibitors (SNRIs). Selective serotonin reuptake inhibitors (SSRI) such as fluoxetine (Prozac) and sertraline (Zoloft) are also a class of antidepressants but have not been found to be effective in treating neuropathic pain. SSRIs do not have any effect on norepinephrine, the main component involved in pain relief. 

SNRIs are the preferred treatment for neuropathic pain as they are generally better tolerated by patients. The most used SNRIs are duloxetine (Cymbalta) and milnacipran (Savella).

Duloxetine is FDA approved for the treatment of diabetic neuropathy and milnacipran is FDA approved for fibromyalgia. Other SNRIs like venlafaxine (Effexor) and desvenlafaxine (Pristiq) are not commonly used for pain.

Unfortunately, SNRIs don’t work immediately. It may take weeks to feel the effects so be patient and take your meds as prescribed for best results. Common side effects include diarrhea, nausea, dry mouth, and dizziness.

What Is Serotonin Syndrome?

Since SNRIs have a serotonin component, they are referred to serotonergic drugs. Serotonergic drugs may cause serotonin syndrome, a dangerous condition which results when too much serotonin builds up in your body.

Symptoms of serotonin syndrome may range from mild (diarrhea and chills) to severe (fever and seizure). Serotonin syndrome may be life-threatening if left untreated.

It can occur if two serotonergic agents are used together or if one serotonergic agent is taken excessively. To avoid overlap of serotonergic agents be sure your doctor is aware of all the medications you are taking.  

Tricyclic Antidepressants (TCAs) for Neuropathic Pain

TCAs are the most studied antidepressants for the treatment of neuropathic pain as they have been around for a long time. Their pain-relieving properties were noted in research from the 1960s.

Similar to SNRIs, TCAs work by regulating norepinephrine, which mediates the analgesic effect. TCAs used for pain are amitriptyline, nortriptyline (Pamelor), doxepin (Silenor), imipramine (Tofranil), Desipramine (Norpramin) and clomipramine (Anafranil).

Side effects may include dry mouth, blurred vision, dizziness, nausea, weight gain, sweating and constipation. Due to the side effects, TCAs are less commonly used in the elderly population. If your doctor recommends TCAs for your pain, he will likely start with a low dose and gradually increase it until an effective dose is achieved. TCAs are also inexpensive which is a plus for low-income people or those without insurance. 

The dose used for neuropathic pain treatment is lower than the dose used for depression treatment. Higher doses are not effective for pain treatment and are associated with more side effects. 

Both TCAs and SNRIs are great options in patients who are suffering from depression or anxiety along with pain. However, they are still considered great options even if depression or anxiety are not present. It is important to note that antidepressants are associated with increased risk of suicidal thoughts or behaviors.

Talk to your doctor or counselor immediately if you feel depressed or suicidal.

Anti-Seizure Medications

Antiseizure medications are also known as anticonvulsants or antiepileptic drugs. This class works by calming down the overactive pain signals caused by damaged nerves.  

As with antidepressants, anti-seizure medications can treat chronic neuropathic pain and may be used even if no seizure disorder is present.

Examples of anti-seizure medications are pregabalin (Lyrica) and gabapentin (Neurontin). Gabapentin is FDA approved for postherpetic neuralgia but can be used in other types of neuropathic pain.

The target dose for pain is 1800mg and the maximum dose is 3600mg. Doses must be adjusted if the patient has any renal problems. Pregabalin is also FDA approved for postherpetic neuralgia as well as diabetic neuropathy and fibromyalgia. The typical starting dose is usually 75mg twice daily. The maximum dose is 600mg. Dose must also be adjusted if patient has kidney problems.

Side effects of gabapentin and pregabalin include weight gain, fluid buildup, sleepiness, and drowsiness. Gabapentin and pregabalin cannot be stopped abruptly; they must be withdrawn gradually to minimize withdrawal symptoms such as confusion, delusions, agitation, and sweating.

Topical Anesthetics

Topical drugs are valuable options in pain management as they achieve relief with a low risk of side effects and drug interactions.

There are many formulations available such as creams, ointments, gels, lotions, and patches. Counterirritants are an over-the-counter class of medications such as salicylates, camphor, and menthol.

Counterirritants work by irritating the nerves as a distraction from the original pain. aCapsaicin can be an effective option and is available as an 8% patch (Qutenza) and as cream, gel, and liquid.

Qutenza is available by prescription only and is FDA approved for neuropathic pain associated with postherpetic neuralgia. The initial response may be seen at one week as opposed to over the counter formulations, which may take up to 6 weeks.

Lidocaine 5% patch (Lidoderm) is also FDA approved for the treatment of postherpetic neuralgia. A maximum of 3 patches may be applied to the painful area per day. Apply the patch for 12 hours then take it off for 12 hours.

Wash hands after application and avoid contact with eyes. Avoid exposing application site to any heat sources such as heat lamps or electric blankets. The patch may cause some redness in application site. 

Corticosteroids

Steroids are powerful anti-inflammatory medications that can be taken orally or injected. If prescription-strength NSAIDs haven’t reduced your pain, your doctor may recommend that you try corticosteroids. They’re responsible for stopping your body from producing the chemical that causes inflammation.

However, as mentioned above, steroids have certain side effects (eg, weight gain), and you can’t just stop taking them—your dose must be slowly decreased. Corticosteroids are used to treat migraines, osteoarthritis, rheumatoid arthritis, and low back pain. Prednisone (Deltasone) and Decadron (Dexamethasone) are examples of corticosteroids.

Muscle Relaxants

These medications are used to reduce aches and pains associated with muscles strains, sprains, or spasms. Muscle relaxants can provide the pain relief you need to manage your daily activities by helping relax tight muscles and improve the quality of sleep you get. Muscle relaxants aren’t typically recommended for treating chronic pain, but they may help with fibromyalgia and low back pain symptoms. Examples of muscle relaxants are carisoprodol (Soma) and baclofen (Lioresal).

Pain Medication Drug Interactions

NSAIDs

• May increase risk of bleeding
• Multiple NSAIDs should not be used together, except if patient is using baby aspirin for heart benefit. If using aspirin for heart and ibuprofen for pain, take aspirin 1 hour before or 8 hours after ibuprofen
• Avoid if you have kidney problems 
• Avoid with alcohol  

Acetaminophen

• Can be used with warfarin, but if used chronically, need to monitor closely as it may increase INR
• Avoid or limit alcohol use due to risk of liver damage

Opioids

• Avoid alcohol completely with all opioids, especially if extended release formulations
• Use caution if already taking a benzodiazepine or muscle relaxant as they can increase the risk for respiratory depression where the breathing slows and can completely stop

SNRIs

• Serotonin syndrome if combined with serotonergic agents such as SSRIs 
• Increases bleeding risk if using along with an NSAID or a blood thinner such as warfarin or supplements like gingko. 
• If taking a blood pressure medication, use caution and monitor blood pressure as SNRIs may increase blood pressure readings
• Separate from Monoamine Oxidase Inhibitors (MAOIs) such as isocarboxazid (Marplan), phenelzine (Nardil), Tranylcypromine (Parnate) and linezolid, by two weeks

TCAs

• Caution if you have existing heart problems as TCAs may cause Qt prolongation, which happens when the heart’s electrical system takes longer than normal to recharge between beats. 
• Separate from Monoamine Oxidase Inhibitors (MAOIs), such as isocarboxazid (Marplan), phenelzine (Nardil), Tranylcypromine (Parnate) and linezolid, by two weeks

Anticonvulsant

• Monitor closely if patient is on opioid therapy

Your Chronic Pain Treatment Plan

The most important thing to remember when taking medications to treat your chronic pain is that you need to be an active participant in your own treatment plan. Don’t be afraid to ask questions—you have to be your own advocate.

Over time, you may need to increase or decrease your dose of medication or perhaps change medications, so it’s essential that you carefully follow your doctor’s directions. Also, be on the lookout for side effects. If you notice any new symptoms, tell your doctor immediately. But don’t stop taking your medication unless your doctor tells you to do so.

Medication Guide

Non-opioids and Other Drugs to Treat Cancer Pain

Non-opioids or non-narcotics, like acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) control mild to moderate pain. Some can be bought without a prescription (over-the-counter). These medicines are stronger pain relievers than most people realize. In many cases, non-opioids are all you’ll need to relieve your pain, especially if you “stay on top of the pain.” Staying on top of the pain means you should take pain relievers regularly, and not wait until your pain level becomes too intense. Waiting too long can make the pain harder to treat.

Acetaminophen

Acetaminophen is commonly known as Tylenol. It relieves pain much the same way NSAIDs do, but it doesn’t reduce inflammation as well as NSAIDs do. People rarely have side effects from the usual dose of acetaminophen. But liver and kidney damage may result if you take large doses of this medicine every day for a long time or drink alcohol with the usual dose. Even moderate amounts of alcohol (3 drinks per day) can lead to liver damage in people taking acetaminophen. You also need to be careful about taking other drugs that have added acetaminophen. See the section on Precautions about aspirin, acetaminophen, and ibuprofen in other medicines.

Your doctor may not want you to take acetaminophen regularly if you’re getting chemotherapy because it can cover up a fever. Your doctor needs to know if you have a fever because it could mean you have an infection, which needs to be treated quickly.

Non-steroidal anti-inflammatory drugs

Non-steroidal anti-inflammatory drugs (NSAIDs) work a lot like aspirin. Either alone or used with other medicines, NSAIDs can help control pain. Before you take any NSAIDs or other non-opioids, ask your doctor, pharmacist, or nurse if it’s safe for you to take it with your other medicines, and how long you can take it. See the chart below for examples of commonly used NSAIDs.

Precautions about NSAIDs

Some people have a higher risk of complications related to NSAIDS. In general, NSAIDs should be avoided by people who:

• Are allergic to aspirin or any other NSAIDs
• Are on chemotherapy
• Are taking steroids
• Are taking blood pressure medicines
• Have stomach ulcers or a history of ulcers, gout, or bleeding disorders
• Are taking oral medicine (drugs by mouth) for diabetes or gout
• Have kidney problems
• Will have surgery within a week
• Are taking blood-thinning medicine
• Are taking lithium

If you drink alcohol, be careful taking NSAIDs. It can cause stomach upset and raise the risk of having reflux or even bleeding in the stomach. Smoking may also increase this risk. NSAIDs may also raise your risk of heart attack or stroke, especially if you take them for a long time.

Children and teens should not take aspirin or products that contain it.

Precautions about aspirin, acetaminophen, and ibuprofen in other medicines

Some opioids also contain aspirin or acetaminophen in the same pill. A few also contain ibuprofen. It can be dangerous if you take these drugs without being aware of this.

• If one of your doctors tells you not to take aspirin or ibuprofen, or if you can’t take NSAIDs for some reason, be sure to check your medicine labels carefully.
• If one of your prescription medicines has acetaminophen in it, and you also take over-the-counter acetaminophen for pain, you can get too much without knowing it. Too much acetaminophen can damage your liver.
• If you’re not sure if a medicine contains aspirin, acetaminophen, or ibuprofen, ask a pharmacist.
• If you take any non-prescription medicine for a cold, sinus pain, or menstrual symptoms while you’re taking pain medicines, read the label carefully. Most of these drugs are combination products that contain aspirin, ibuprofen, or acetaminophen. Check with a pharmacist to find out what you can safely take with your pain medicines.

Side effects of acetaminophen and NSAIDS*

* NSAIDs = Non-steroidal anti-inflammatory drugs

How drugs are named

A drug may have as many as 3 different names: Brand, generic, and chemical. For example:

Brand names: Tylenol, Tempra, Liquiprin, Anacin, Paramol (and many more)

Drug companies give their products brand names, and some products have more than one brand name. You should also know that the same brand name may be used on different drugs, since the name belongs to the company. Read the labels to see what ingredients are in each medicine.

Generic names: acetaminophen

The US Food and Drug Administration (FDA) approves the generic names by which drugs are usually known. Sometimes medicines can have the same generic name, but are made by different companies. Because the companies may produce the medicines differently, they may differ slightly in the way they’re absorbed by the body. For this reason, your doctor may sometimes prefer that you take a brand-name drug. Generic drugs usually cost less than brand-name ones. Ask your doctor, nurse, or pharmacist if you can use a cheaper generic medicine. Pharmacists are careful to get high-quality generic products, so it’s often possible to substitute a generic.

Chemical names: N-(4-hydroxyphenyl) acetamide

Chemical names tend to be long and hard to pronounce, so they are not used often.

What you need to know about drug names

Many pain relievers are available under both generic and brand names. Your doctor, nurse, or pharmacist can tell you the generic and common brand names of any medicines you’re taking. It’s always good to know both because you may hear either name when talking about your medicines. Knowing both names can also keep you from getting confused when keeping track of prescriptions and pill bottles. It can also keep you from taking too much of the same medicine if it’s prescribed using 2 different names.

Drug additives

Along with the main substance (for example aspirin, acetaminophen, or ibuprofen), some brands contain additives. Common additives include:

• Buffers (such as magnesium carbonate or aluminum hydroxide) to decrease stomach upset
• Caffeine to act as a stimulant and to improve the effect of some pain medicines
• Antihistamines (such as diphenhydramine or pyrilamine) to help you relax or sleep

Medicines with additives can cause side effects you wouldn’t expect from the main drug. For example, antihistamines sometimes cause drowsiness. This may be all right at bedtime, but it could be a problem during the day. Additives tend to increase the cost of non-prescription pain relievers. They can also change the action of other medicines you may be taking or even keep your body from absorbing the other drug. When you start a new drug, even one you can get over the counter, always talk with your doctor or pharmacist about what you’re already taking to see if the combination can cause harmful effects.

Plain aspirin, acetaminophen, or ibuprofen probably works as well as the same medicines with additives. But if you find that a brand with certain additives is a better pain reliever, ask your doctor, nurse, or pharmacist if the additives are safe for you. Talk with them about any concerns you may have about the drugs contained in your non-prescription pain medicines.

Other medicines commonly used to help treat cancer pain

Many different types of medicines can be used along with (or instead of) opioids and non-opioids to help relieve cancer pain. Some of these medicines can help relieve pain or increase the effect of the pain medicine. Others lessen the side effects of pain medicines. These drugs are often started at low doses and increased over time. The table shows the classes and some examples of drugs that are not really pain medicines, but might be used to help you get the best pain relief with as few side effects as possible.

How to decipher a prescription for eyeglasses.

So, after a thorough examination by an ophthalmologist, you have a prescription for glasses. What to do and how to figure out all these “squiggles” and read the prescription for glasses? The answer is quite simple, and we will try to give it to you.

What you need to know in the recipe:

OD (oculus dexter) —right eye

OS (oculus sinister) —left eye

It is important to enter your recipe values ​​correctly for the right and left eyes.Very often these parameters have different meanings for one and the other eye.

Sometimes they write OU (oculus uterque), which means “both eyes”, that is, they are the same

Sph (sphere) Sphere – the optical power of the lens in diopters ( D or D ), expressed in negative or positive numerical values ​​(“+” for hyperopia or “-” for myopia). Farsighted – poorly see near, nearsighted poorly see in the distance.

Cyl (cylinder) – the optical power of cylindrical lenses for the correction of astigmatism, it can also be with a “+” or “-” sign.In the case of “astigmatism”, the “cylinder” parameter is included in the prescription for spectacle lenses, which compensates for this distortion. The meaning of “cylinder” can be found in your eyeglass prescription. Basically it is written as “Cyl”, “S.”, “Tsil.” abbreviating the word “Cylinder”

Ax (Axis) – The axis of inclination of the cylinder in degrees from 0 to 180, allows you to correct the refraction of light rays in a particular meridian

DP (distantio pupillorum) – the distance between the centers of the pupils in millimeters, sometimes it is indicated for each eye by relativity (we add and get the total value)

Add (addition) – the difference in diopters between the distant and near vision zones, taken into account for bifocal or progressive glasses when correcting presbyopia (for example, lenses for distance +1, 0D, for near + 2.5D, which means that the add-on will be +1.5 D), the maximum value of the add-on step is + 3.0D

Prism – the power of the prismatic lens in prismatic diopters or the triangle icon.It is used in lenses for the correction of strabismus indicating the direction of the base of the prism: up, down, outward (towards the temple), inward (towards the nose).

Decoding of the recipe reading from the Autorefractometer

The printout of the computer diagnostics of vision looks like this, we will explain with an example how to read it.

1) Ref – results of refractometry (refraction).

2) R – right eye.

3) L – left eye.

4) Sph – the optical power inherent in a spherical lens, which corresponds to refraction in one of the 2 main meridians of the eye.

5) PD – interpupillary distance.

6) The results of measuring the radius of curvature of the cornea in its maximum and minimum meridians, expressed in millimeters.

7) R1 and R2 are the results of measurements in the maximum and minimum meridians of the cornea of ​​the eye.

8) VD – vertex distance.

9) # – data, the reliability of which is questionable.

10) Cyl – the optical power of a cylindrical lens, the addition of which to a spherical lens with an optical power corresponding to one of the two main meridians of the given eye (see item 4), reflects the refraction of the eye in the other main meridian. Usually negative (minus) cylinders are preset in autorefractometer settings. The size of a cylinder always indicates the difference in refraction of the two main meridians.

11) Ax – the axis of the cylindrical lens refers to item – 10.

12) Average refractive index in the two main meridians of the eye, expressed as a prescription for glasses.

13) Ker – results of keratometry.

14) The average of the obtained measurements of the radius of curvature of the cornea in millimeters and the refractive power in its minimum and maximum meridians D – diopters. (for fitting contact lenses)

15) The results of measuring the refraction of the cornea in its minimum and maximum meridians, expressed in diopters (D).Depending on the refractometer model, the printout may show S.E.

A printout from this device serves as an action for further examination by an ophthalmologist, after which glasses or contact lenses are selected by the fitting method and a full-fledged prescription for making glasses and wearing lenses is written out

How to read a prescription for contact lenses

Prescription on contact lenses is different from a prescription for glasses.As we explained above on decoding the paper prescription, in addition to the optical power of the diopter or refraction, the prescription for the MCL contains information on the radius of curvature of the cornea, denoted by: BC, which relates the size of the lens and your eye, also the Dia of the lens diameter.

BC – radius of curvature of the cornea. This parameter is necessary to select the correct radius of curvature of the MCL, it is usually prescribed on the packaging or blister of contact lenses and is usually indicated, as a number with one digit after the decimal point. Common BC – 8.4, 8.5, 8.6

DIA – contact lens diameter. It depends on the size of your cornea. May not be included in the recipe. is the standard for each brand of lenses prescribed for the recommended purchase of those lenses.

If you are prescribed toric or bifocal contact lenses to correct astigmatism, they will have more performance.
The following parameters are added to the previous ones: Cyl (cylinder) (cylinder) and Ax – the axis angle can have values ​​from 0 to 180 degrees ADD – addiction – is indicated when assigning multifocal contact lenses.

Please note that contact vision correction is individual, the selection and control of wearing contact lenses requires careful ophthalmological examination and observation. Follow the doctor’s instructions, do not exceed the period of wearing contact lenses and promptly change them to new ones.

Khondra-Sila instructions for use, price in pharmacies in Ukraine, analogues, composition, indications | Hondra-Syla capsules of the Farmak company

The pharmacological action of the drug Hondra-Sila is due to the components that make up it – chondroitin sulfate and glucosamine hydrochloride.

Chondroitin sulfate is a high molecular weight mucopolysaccharide involved in the construction of cartilage tissue. Reduces the activity of enzymes that destroy articular cartilage and stimulates the regeneration of articular cartilage. Chondroitin sulfate reduces the activity of the inflammatory process in the early stages and thus slows down the degeneration of cartilage tissue. It helps to reduce pain, improve joint function, and reduce the need for NSAIDs in patients with osteoarthritis of the knee and hip joints.

Glucosamine hydrochloride has chondroprotective properties, reduces the deficiency of glucosaminoglycans in the body, takes part in the biosynthesis of proteoglycans and hyaluronic acid.Due to the tropism to cartilage tissue, glucosamine hydrochloride initiates the process of fixing sulfur during the synthesis of chondroitinsulfuric acid. Glucosamine hydrochloride selectively acts on the articular cartilage, is a specific substrate and stimulator of the synthesis of hyaluronic acid and proteoglycans, inhibits the formation of superoxide radicals and enzymes that cause damage to cartilage tissue (collagenase and phospholipase), prevents the destructive effect of glucocorticoids on chondrocytes and the disruption of biosynthesis biosynthesis.

Pharmacokinetics. Suction. After a single oral administration of the drug in an average therapeutic dose C _max of chondroitin sulfate in the blood plasma is achieved after 3-4 hours, in the synovial fluid – after 4-5 hours. The bioavailability of chondroitin sulfate is 13%. Excretion is carried out mainly by the kidneys within 24 hours.

After oral administration, 90% of glucosamine is absorbed from the intestine, more than 25% enters the cartilage tissue and synovial membranes of the joints from blood plasma.In the liver, part of the drug is metabolized to urea, carbon dioxide and water.

Bioavailability of glucosamine is 25% due to the first passage through the liver. The highest concentrations of glucosamine are found in the liver, kidneys and articular cartilage. About 30% of the applied dose persists for a long time in bone and muscle tissues. It is excreted mainly in the urine unchanged, partially in the feces. T _½ is 68 h.

degenerative-dystrophic diseases of the joints and spine: osteoarthritis, periarthritis of the shoulder scapula, osteochondrosis, fractures (to accelerate the formation of callus).

the drug should be taken orally with a small amount of water.

Adults and children over 12 years old : 2 capsules 3 times a day. The minimum duration of treatment is 2 months. The course of treatment is usually repeated at intervals of 3 months.

Gelling Agents – Master Class for Confectioners

For the preparation of most desserts, we use a standard set of ingredients: flour, sugar, eggs, dairy products, a variety of nuts, fruits.If our task is to cook something a little more complicated than charlotte, then we absolutely cannot do without basic knowledge of gelling agents. Jelly, compote, mousse, soufflé, marshmallow, marshmallow, marshmallow … and the list goes on. Many desserts or their constituent parts cannot be prepared without gelatin, agar-agar or pectin. We need these three main gelling agents for structure, stability and texture. But apart from the “one mission” all these ingredients, perhaps, have little in common. Who is who ?! Or how to make each of the agents work for themselves – we tell and show.

Gelatin

A protein product of animal origin, which is made from pork skins, tendons, cartilage and bones by prolonged boiling with water. Gelatin is used in both sweet and savory foods. Gelatin is available in two forms: sheet and powder. In order to prepare gelatin for use, the powder is soaked in cold water in a ratio of 1: 5. Leaf gelatin is usually added to a large amount of cold water for a few minutes and gently wrung out before use.

Soaked gelatin is added to a liquid heated to 80-90 degrees, or it is melted in a microwave oven or in a water bath, without boiling, and combined with a warm gelling mass. The most important rule when working with gelatin is that it should never be boiled under any circumstances. To obtain light jelly, 1.5-2 g of gelatin per 100 g is used. liquid, for a more stable jelly 4 g for all the same 100 g, for dense – 6 g. This proportion generally works great for gelling fruit or berry purees and juices.More acidic berries and fruits require an increase in the percentage of gelatin in the recipe, and some, in general, separate dances with tambourines. For example, pineapple, papaya, ginger, melon, passionfruit and kiwi contain enzymes that destroy protein compounds, therefore, before jelling these fruits, you need to destroy these very substances by subjecting them to heat treatment. In other words, these fruits must be heated to a temperature not lower than 85C. In addition, acids such as vinegar or wine can also weaken the strength of gelatin.But sugar, alcohol and lactose, on the contrary, enhance its gelling properties.

Gelatin is an essential ingredient for mousse cakes, marshmallows and jellies. In addition to its main binding function, it is gelatin that gives desserts a viscous, slightly stretchy texture.

Powder or sheet? – a question that is often asked by novice pastry chefs. In fact, it’s just a matter of convenience and habit. Both forms are equivalent to each other, so you can safely interchange them.Pay attention only to the strength of gelatin, which is measured in Bloom degrees. Unfortunately, not all manufacturers indicate the strength of the gelatin on the label. If you use non-professional gelatin without indicating its strength on the package, then most likely it will be in the 180-200 Bloom range. You can search the Internet yourself for more accurate information on a specific brand of gelatin.

Agar-agar

Vegetable gelling powder derived from red algae.The gelling properties of agar are several times higher than the capabilities of gelatin. Therefore, to obtain a stable gel, only 1 g of agar per 100 g of liquid is enough.

In order to prepare the agar-agar for work, it is also soaked in a small amount of cold water (the proportion is the same as that of gelatin), then the gelling mass is heated, agar is added to it and boiled for several minutes. The main difference in working with agar is that the future jelly must be boiled! Agar-agar begins to solidify already at a temperature of about 40C, it is a fairly stable gelling agent.In addition, agar agar is reversible. That is, if you incorrectly calculated its amount and got too dense or too soft jelly, then the mass can be heated again and the amount of agar can be adjusted. Agar-agar is an excellent helper for the preparation of fruit and berry layers, and without it it is impossible to cook marshmallows, Bird’s milk cake and much more.

In contrast to the stretching texture when using gelatin, jelly on agar agar rather acquires a loose, crumbly texture.It can be compared to “broken glass”. It is because of the ambiguity of the structure of jelly on agar that it has both its fans and ardent opponents.

Pectin

Pectin, along with agar-agar, is a vegetable gelling agent, but unlike the second, it is obtained from fruits and some vegetables. Pectin is widely used in the confectionery industry, because it can act in completely different roles: gelling agent, thickener, stabilizer, moisture retainer.

Apples and citrus fruits (orange, lemon, grapefruit, etc.) have the highest pectin content, which is why apple and citrus pectins of the same name are the most popular. The first is usually a little darker than the second, but there is no fundamentally huge difference between them. Both pectins are thermally irreversible, which means you cannot re-dissolve them when heated.

A completely different conversation is NH pectin, or nappage.Its main difference (besides the price) is its reversibility. This property allows you to adjust the texture in any direction: from jelly to sauce. And if pectin is combined with agar-agar or gelatin, then we get an infinite number of texture variations. It is for this variability that pectin is especially appreciated among confectioners. In addition, it is pectin in its pure form that gives the most natural texture for berry and fruit layers. For light gelling a la confiture, 2 g is enough. pectin per 100 gr.puree, for a more stable result, increase this amount to 5-6 grams.

Regardless of the type of pectin chosen, you should follow the basic rules for its use. First, pectin is pre-mixed with sugar in a 1: 2 or 1: 3 ratio. Secondly, you need to add pectin to the workpiece with a gentle “rain” at a temperature of 50C, actively stirring the mass. Thirdly, after the introduction of the pectin into the workpiece, it must be boiled for about a minute.Well, and the fourth rule: after boiling, citric acid is added to the liquid, which helps to fix the gelled mass.

Bonus track for those who have mastered the theory: recipe for citrus marmalade.

Approximately 1 kg. ready-made marmalade:

• 250 gr. orange pulp;

• 150 gr. grapefruit pulp;

• 100 gr. mandarin pulp;

• 500 gr.Sahara;

• 100 gr. glucose;

• 15 gr. pectin;

• 50 gr. Sahara;

• 4 gr. citric acid.

In general, we need 500 grams of pulp of any citrus fruit. You can take only pure orange, but replacing part of the puree with tangerine, grapefruit or lime, you can get a more sophisticated flavor combination.

In a saucepan, combine citrus puree, sugar and glucose.We need the last ingredient to prevent the sugaring process. Heat the mixture to 50-60C and add pectin mixed with 50 gr. sugar, a neat “rain”. Boil the mixture to 110C, stirring vigorously. Prepare a 20X25 cm frame by tightening the bottom with cling film and pour the puree into a mold.

Leave the marmalade to solidify for about 15 hours. After completing the process, cut the marmalade into squares and roll in sugar.

With love, the Tortomaster team and Maria Sukhomlina.

One Japanese song at one time gained worldwide fame – abroad it is known under the name “Sukiyaki”. Sukiyaki is a very tasty and aesthetic dish, and it is very easy to prepare it.It is simply thinly sliced ​​beef with vegetables, cooked with soy sauce, sugar, sake and sweet rice wine mirin . If you don’t have beef on hand, you can use other meat, even chicken. In the cold season, it is a pleasure to eat sukiyaki with family or friends.

Ingredients (for 2-3 persons)

• Thinly sliced ​​beef – 350 g
• Vegetables of your choice – salad chrysanthemum, green onions, mushrooms (for example, shiitake), corresponding amount
• Tofu – 1 package (300 g )
• Water or broth- dashi from seaweed, corresponding amount
• Several eggs
• Wheat udon noodles (can be cooked very last)
• Cooking mix:
  • Sugar – 0.5 cups
  • Sweet rice wine (mirin) – 0.5 cups (if there is no mirin, instead of it you can increase the amount of sake and sugar by one and a half times)
  • Soy sauce – 0.5 cups
  • Sake – 0.5 cups

Method of preparation

1. Pour one third of the prepared mixture of sugar, sake, mirin and soy sauce into a saucepan for sukiyaki, stir.
2. Cut vegetables, tofu and meat into small pieces for easy eating.
3. Heat the saucepan and put a few pieces of beef and onion stalks in the hot cooking mixture. Boil the meat slightly and eat it.

4. Pour the remaining two-thirds of the mixture of sake, mirin, sugar and soy sauce into a saucepan, add the rest of the ingredients, select pieces from the pan as it cooks and eat. If you like eggs, we recommend breaking the egg into a bowl and dipping the pieces of food into the egg before eating.As the mixture boils in the saucepan, add water or seaweed broth. At the end, you can put boiled udon noodles in a saucepan.

Cooking tips

• This type of dish, nabemono , which is cooked in a saucepan, is great because everyone can choose and eat what they like. These dishes are loved by both adults and children, they are fun to cook, and they help informal communication.
• Try vegetables that grow in your area – chicory salad, arugula, etc.The main ingredients of sukiyaki are meat, onion stalks and shiitake mushrooms, and the ingredients can be varied.
• Tofu (bean curd) should be chosen more dense ( momen ), since it does not fall apart in boiling water.
• If thinly sliced ​​beef is not available, other meats can be sliced ​​and beaten. The best is, of course, Japanese wagyu beef, but delicious sukiyaki can also be made with chicken.
• You can put all the ingredients in a saucepan and serve, but it is more beautiful when they lie separately on a large platter – the table then looks festive, and everyone can gradually put the pieces they want to eat into the pan and cook.Green vegetables in boiling water quickly lose their appearance, so it is better to put them last.

Effect of other medicines on sildenafil

In vitro studies

Sildenafil is metabolized mainly by the action of cytochrome P450 (CYP) isoenzymes 3A4 (main pathway) and 2C9 (accessory pathway).Therefore, inhibition of these liver isoenzymes can reduce the clearance of sildenafil, and stimulation of these isoenzymes can increase the clearance of sildenafil.

In vivo studies

Population pharmacokinetic analysis of clinical trial data has shown a decrease in sildenafil clearance with the simultaneous use of CYP3A4 inhibitors (cimetidine, ketoconazole, erythromycin). Despite the fact that with the simultaneous use of sildenafil and CYP3A4 inhibitors, there was no increase in the frequency of adverse events, the use of the drug at an initial dose of 25 mg should be considered.

Simultaneous administration of a single dose (100 mg) of sildenafil against the background of an equilibrium concentration of the HIV protease inhibitor ritonavir, which is a potent inhibitor of P450 (500 mg twice a day) leads to a 300% (4 times) increase in the Cmax of sildenafil and 1000% (11 times) an increase in the AUC of sildenafil in plasma. After 24 hours, the plasma level of sildenafil was about 200 ng / ml, compared to about 5 ng / ml after administration of sildenafil alone. This is consistent with the reported effects of ritonavir on a wide range of P450 substrates.Sildenafil has no effect on the pharmacokinetics of ritonavir. Based on the results of pharmacokinetic studies, the co-administration of sildenafil with ritonavir is not recommended, in any case, the maximum dose of sildenafil should not, under any circumstances, exceed 25 mg in 48 hours.

The simultaneous administration of a single dose (100 mg) of sildenafil and saquinavir (1200 mg three times a day), an HIV protease inhibitor and an inhibitor of CYP3A4, against the background of reaching a constant concentration of saquinavir in the blood, leads to an increase in the Cmax of sildenafil by 140% and an increase in the AUC of sildenafil by 210 %.Sildenafil has no effect on the pharmacokinetics of saquinavir. Stronger CYP3A4 inhibitors such as ketoconazole and itraconazole may cause more pronounced changes.

The combined use of a single dose of sildenafil (100 mg) and erythromycin (500 mg twice a day for 5 days), a moderate inhibitor of CYP3A4, against the background of reaching a constant concentration of erythromycin in the blood, leads to an increase in the AUC of sildenafil by 182%. Taking azithromycin (500 mg daily for 3 days) in healthy male volunteers did not affect the AUC, Cmax, tmax, the constant rate of elimination and the half-life of sildenafil or its main circulating metabolite.In healthy volunteers, co-administration of cimetidine (800 mg), a cytochrome P450 inhibitor and a nonspecific CYP3A4 inhibitor with sildenafil (50 mg) caused an increase in plasma concentration of sildenafil by 56%.

Grapefruit juice is a weak inhibitor of CYP3A4 and may cause a slight increase in plasma levels of sildenafil.

Single doses of antacids (magnesium hydroxide / aluminum hydroxide) do not affect the bioavailability of sildenafil.

Pharmacokinetic data from clinical trials have shown that CYP2C9 inhibitors (such as tolbutamide, warfarin), CYP2D6 inhibitors (such as selective serotonin reuptake inhibitors, tricyclic antidepressants), thiazide and thiazide-like diuretics, loop and potassium-sparing channel inhibitors, β-adrenergic receptor antagonists or inducers of CYP450 metabolism (such as rifampicin, barbiturates) do not affect the pharmacokinetics of sildenafil.

In a study in healthy male volunteers, the co-administration of an endothelin antagonist, bosentan (a moderate inducer of CYP3A4, CYP2C9 and possibly CYP2C19 isoenzymes) at equilibrium (125 mg twice daily) and sildenafil at steady state (80 mg three times daily ) led to a decrease in AUC and Cmax of sildenafil by 62.6% and 55.4%, respectively. Thus, the concomitant use of potent CYP3A4 inducers such as rifampicin will further decrease the plasma concentration of sildenafil.

Nicorandil has the properties of a potassium channel activator and a nitrate-like effect. The nitrate component of nicorandil has the potential to enter into clinically significant interactions with sildenafil.

Effect of sildenafil on other medicinal products

In vitro studies

Sildenafil is a weak inhibitor of cytochrome P450 isoenzymes 1A2, 2C9, 2C19, 2D6, 2E1 and 3A4 (1C50> 150 μM).When the peak plasma concentration of sildenafil is about 1 μmol at the recommended doses, it is unlikely that sildenafil alters the substrate clearance of these isoenzymes.

There are no data on the interaction of sildenafil and nonspecific phosphodiesterase inhibitors such as theophylline and dipyridamole.

In vivo studies

In accordance with the known effect on the NO / cGMP signaling cascade, sildenafil potentiates the hypotensive effect of nitrates, therefore, simultaneous use with nitric oxide donors or nitrates in any form is contraindicated.

Riociguat: In preclinical studies, a stronger decrease in systemic blood pressure was observed with the use of PDE-5 inhibitors with riociguat. In clinical trials, riociguat increased the hypotensive effect of PDE-5 inhibitors. There was no evidence of a beneficial clinical effect of this combination in the study population. Concomitant use of riociguat with PDE-5 inhibitors, including sildenafil, is contraindicated.

The simultaneous use of sildenafil in patients taking α-blockers can lead to symptomatic hypotension in some predisposed patients.This condition is most likely to develop within 4 hours of taking a dose of sildenafil.

In three special studies of drug interactions in patients with benign prostatic hyperplasia (BPH) with a stable condition during therapy with doxazosin, the alpha-blocker doxazosin (4 mg and 8 mg) and sildenafil (25, 50 and 100 mg) were simultaneously prescribed. In the population of this study, there was an average additional decrease in blood pressure in the horizontal position of 7/7 mm Hg.Art., 9/5 mm Hg. Art. and 8/4 mm Hg. Art., and in an upright position – by 6/6 mm Hg. Art., 11/4 mm Hg. Art. and 4/5 mm Hg. Art. respectively. When sildenafil and doxazosin were concomitantly administered to stable patients treated with doxazosin, there have been rare cases of symptomatic postural hypotension. In such cases, the patients’ symptoms included dizziness, but no fainting was noted.

There were no significant interactions when sildenafil (50 mg) was taken together with tolbutamide (250 mg) or warfarin (40 mg) – drugs that are metabolized by CYP2C9.

Sildenafil (50 mg) does not increase the bleeding period caused by acetylsalicylic acid (150 mg).

Sildenafil (50 mg) does not enhance the hypotensive effect of alcohol in healthy volunteers with an average maximum blood alcohol level of 80 mg / dL.

In patients who used sildenafil, there were no differences in the safety profile compared to placebo with the simultaneous use of such classes of antihypertensive drugs: diuretics, β-blockers, ACE inhibitors, angiotensin II receptor antagonists, antihypertensive drugs (vasodilators and central blockers), adrenergic antagonists neurons, calcium channel blockers and alpha-blockers.In a special clinical study of drug interaction, where sildenafil (100 mg) was taken together with amlodipine, in patients with arterial hypertension, an additional decrease in systolic blood pressure in the supine position by 8 mm Hg was observed. Art. The corresponding additional reduction in diastolic blood pressure in the supine position was 7 mm Hg. Art. This additional reduction in blood pressure was similar to that observed in a group of healthy volunteers using sildenafil alone.

Sildenafil (100 mg) does not affect the pharmacokinetics of the equilibrium concentration of saquinavir and ritonavir, HIV protease inhibitors, which are substrates of the CYP3A4 isoenzyme.

In healthy male volunteers, taking equilibrium doses of sildenafil (80 mg three times a day) led to an increase in the AUC and Cmax of bosentan (125 mg twice a day) by 49.8% and 42%, respectively.

Use during pregnancy and lactation

Sildenafil is not intended for use in women.

There have been no adequate and well-controlled studies in women during pregnancy and during breastfeeding. In studies of the effect of oral sildenafil on reproductive function in rats and rabbits, no significant adverse reactions were found.

Single oral administration of sildenafil 100 mg to healthy volunteers did not affect sperm motility or morphology.

Influence on the ability to drive vehicles and use mechanisms

The effect of sildenafil on the ability to drive vehicles and use mechanisms has not been studied.In clinical trials of sildenafil, cases of dizziness and decreased vision have been reported, patients should be aware of the individual effect of the drug on the body before driving a car or operating machinery.
