How many milligrams of acetaminophen can an adult safely take. What are the risks of acetaminophen overdose. How to avoid accidental acetaminophen toxicity. What factors affect acetaminophen safety and dosing.

Understanding Acetaminophen: Uses and Risks

Acetaminophen, the active ingredient in Tylenol and numerous other over-the-counter medications, is widely used for pain relief and fever reduction. While billions of doses are consumed safely each year, it’s crucial to understand proper dosage to avoid potential risks.

Acetaminophen differs from nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and aspirin in that it doesn’t reduce inflammation. However, it has the advantage of being gentler on the stomach, making it a valuable option for those who can’t tolerate NSAIDs.

Why is acetaminophen dosage important?

Acetaminophen has a narrower safety margin compared to NSAIDs. Exceeding the recommended dose can lead to liver damage, potentially resulting in the need for a liver transplant or even death. The body converts a small portion of acetaminophen into a toxic byproduct, which can accumulate to dangerous levels if too much is taken.

Recommended Acetaminophen Dosages for Adults

For the average healthy adult, the generally recommended maximum daily dose of acetaminophen is 4,000 milligrams (mg) from all sources. However, it’s safer to aim for a lower limit whenever possible.

• Safest maximum daily dose: 3,000 mg
• Absolute maximum daily dose: 4,000 mg

How much acetaminophen can you take at once?

The appropriate single dose depends on the strength of the acetaminophen product:

• 325 mg tablets: 1-2 pills every 4-6 hours
• 500 mg tablets: 1-2 pills every 4-6 hours
• 650 mg extended-release tablets: 1-2 pills every 8 hours

It’s crucial to never exceed the recommended dosage or frequency, even if pain persists. Consult a healthcare professional if you need additional pain management.

Factors Affecting Acetaminophen Safety

Several factors can influence how your body processes acetaminophen, potentially increasing the risk of toxicity even at recommended doses:

Body weight and size

Individuals with a smaller body size should stay on the lower end of the recommended dose range. A maximum daily dose of 3,000 mg is advisable for those with lower body weight.

Alcohol consumption

Alcohol causes the liver to convert more acetaminophen into toxic byproducts. Men should limit alcohol intake to no more than two standard drinks per day when taking acetaminophen, while women should stick to one drink per day.

Existing liver conditions

People with liver disease or a history of heavy alcohol use may be more susceptible to acetaminophen-induced liver damage. These individuals should consult their healthcare provider for personalized dosing recommendations.

Age

Older adults may process acetaminophen more slowly, potentially increasing the risk of toxicity. They should be particularly cautious about staying within recommended limits.

Avoiding Accidental Acetaminophen Overdose

With over 600 products containing acetaminophen, it’s easy to inadvertently consume too much. Follow these precautions to stay safe:

1. Check labels carefully: Many cold, flu, and combination pain relievers contain acetaminophen. Always read ingredient lists to avoid double-dosing.
2. Know your pill strength: Acetaminophen products come in various strengths (325 mg, 500 mg, 650 mg). Be especially cautious with higher-strength formulations.
3. Don’t exceed recommended doses: Resist the temptation to take “just a little more” for stubborn pain.
4. Be mindful of alcohol intake: Reduce or avoid alcohol when taking acetaminophen regularly.
5. Consider potential drug interactions: Some prescription medications may interact with acetaminophen. Consult your healthcare provider or pharmacist about potential risks.

Recognizing Acetaminophen Toxicity

Early symptoms of acetaminophen overdose can be subtle and easily mistaken for other conditions. Be alert for:

• Nausea and vomiting
• Loss of appetite
• Abdominal pain (especially in the upper right quadrant)
• Fatigue
• Sweating
• Pale skin

If you suspect an acetaminophen overdose, seek immediate medical attention. Prompt treatment is crucial for preventing severe liver damage.

Can acetaminophen toxicity occur from long-term use?

Yes, chronic use of acetaminophen, even at recommended doses, can potentially lead to liver problems in some individuals. This risk is higher for those who consume alcohol regularly or have existing liver conditions. If you need to take acetaminophen daily for chronic pain management, consult your healthcare provider for personalized guidance.

Alternatives to Acetaminophen

While acetaminophen is an effective pain reliever for many, it’s not the only option available. Consider these alternatives when appropriate:

• NSAIDs (ibuprofen, naproxen): Effective for pain and inflammation, but may cause stomach irritation
• Topical pain relievers: Creams, gels, or patches for localized pain
• Non-drug approaches: Heat/cold therapy, physical therapy, massage, acupuncture
• Prescription pain medications: For severe or chronic pain under medical supervision

Always consult your healthcare provider before switching pain management strategies, especially if you have underlying health conditions or take other medications.

Special Considerations for Chronic Pain Management

For individuals dealing with chronic pain conditions, long-term acetaminophen use requires careful consideration:

Is it safe to take the maximum dose of acetaminophen daily for extended periods?

While the maximum daily dose of 4,000 mg is considered safe for most healthy adults, taking this amount consistently over long periods may increase the risk of liver problems. For chronic pain management, it’s advisable to:

• Use the lowest effective dose
• Aim for a daily maximum of 3,000 mg whenever possible
• Explore alternating or combining acetaminophen with other pain management strategies
• Have regular check-ups with your healthcare provider, including liver function tests

Your doctor may recommend a personalized dosing plan based on your individual health status, other medications, and pain management needs.

Acetaminophen Safety in Special Populations

Certain groups may need to take extra precautions when using acetaminophen:

Pregnant women

Acetaminophen is generally considered safe during pregnancy when used as directed. However, pregnant women should consult their healthcare provider before taking any medication, including over-the-counter pain relievers.

Children

Pediatric dosing for acetaminophen is based on weight and age. Always use the appropriate children’s formulation and follow dosing instructions carefully. Never give adult-strength acetaminophen to children without medical guidance.

Older adults

Seniors may be more susceptible to acetaminophen’s effects due to age-related changes in liver function and potential interactions with other medications. They should be particularly cautious about staying within recommended dosage limits and may benefit from starting with lower doses.

People with liver or kidney disease

Individuals with compromised liver or kidney function should consult their healthcare provider before using acetaminophen. They may need dose adjustments or alternative pain management strategies.

The Importance of Medication Awareness

Understanding proper acetaminophen use is part of a broader need for medication awareness. To promote safe and effective use of all medications:

• Keep a list of all medications you take, including over-the-counter drugs and supplements
• Read labels carefully and follow dosing instructions
• Ask your healthcare provider or pharmacist about potential drug interactions
• Store medications safely, out of reach of children
• Dispose of unused or expired medications properly

By being informed and vigilant about medication use, you can maximize the benefits while minimizing potential risks.

How can you stay informed about acetaminophen safety?

To stay up-to-date on acetaminophen safety and proper use:

• Consult reputable health websites and resources
• Talk to your healthcare provider or pharmacist regularly about your pain management regimen
• Pay attention to any FDA announcements or updates regarding acetaminophen
• Consider using medication tracking apps to monitor your acetaminophen intake

Remember, while acetaminophen is generally safe when used as directed, it’s essential to approach all medication use with caution and awareness.

Acetaminophen safety: Be cautious but not afraid

Cold, cough, and flu season is a good time to revisit the risks of acetaminophen—the pain and fever reliever in Tylenol and many other over-the-counter medications. Billions of doses of acetaminophen are consumed safely every year, but deaths still occur from accidental overdoses and thousands of people end up in the emergency room. More than 600 products contain acetaminophen, and inadvertently combining them can nudge you into the red zone.

“People don’t realize that these doses all add up, and before you know it you’ve exceeded the recommended dose of acetaminophen,” says Dr. Melisa Lai Becker, instructor in medicine at Harvard Medical School and a specialist in emergency medicine and toxicology at Harvard-affiliated Cambridge Health Alliance.

Acetaminophen safe dosage basics

Acetaminophen controls pain and fever but does not reduce inflammation, as does aspirin and the other widely consumed nonsteroidal anti-inflammatory drugs (NSAIDs) ibuprofen (Advil, Motrin, generics) and naproxen (Aleve, generics). But unlike NSAIDs, acetaminophen does not irritate the stomach and intestinal lining. That means a person who cannot tolerate NSAIDs can still take acetaminophen. It’s an important drug for controlling chronic pain in older adults.

The hitch is that acetaminophen also has a narrower window of safety compared with ibuprofen and naproxen. NSAIDs can make you sick, too, but it takes a larger amount to reach a dangerous overdose. Taking too much acetaminophen can damage the liver, sometimes leading to a liver transplant or death.

The body breaks down most of the acetaminophen in a normal dose and eliminates it in the urine. But some of the drug is converted into a byproduct that is toxic to the liver. If you take too much—all at once or over a period of days—more toxin can build up than the body can handle.

For the average healthy adult, the generally recommended maximum daily dose is no more than 4,000 milligrams (mg) from all sources. But in some people, doses close to the 4,000 mg daily limit for adults could still be toxic to the liver. It’s safest to take only what you need, and to not exceed 3,000 mg a day whenever possible, especially if you use acetaminophen often.

How to stay within limits

If you ever have concerns about how much acetaminophen you can tolerate based on your age, body size, and health status, talk to your doctor or pharmacist. Here are some general precautions for avoiding an accidental overdose of acetaminophen.

• Cold and flu remedies count. When you reach for an over-the-counter cough, cold, or flu product, take a look at the label. Does it contain acetaminophen?
• Know the milligrams in your pills. In acetaminophen products available over the counter, each pill may contain 325, 500, or 650 milligrams of the drug. Be extra cautious when taking 500 or 650 milligram pills.
• Stick to recommended doses. When taking acetaminophen, don’t be tempted to add a little extra to the recommended dose. A small-bodied person should stay on the low end of the recommended dose range (3,000 mg).
• Easy on the alcohol. Drinking alcohol causes the liver to convert more of the acetaminophen you take into toxic byproducts. Men should not have more than two standard drinks per day when taking acetaminophen (one drink per day for women).
• Know if your medications interact. Ask your doctor or pharmacist if any of your prescription medications could interact badly with acetaminophen.

How much should you worry?

Tens of thousands of people become ill every year from taking too much acetaminophen. In a smaller number of cases—several hundred per year—it leads to death. But it need not happen to you. “Read the labels and stick to the guidelines,” Dr. Lai Becker advises.

The maximum daily dose for a healthy adult who weighs at least 150 pounds is 4,000 milligrams (mg). However, in some people, taking the maximum daily dose for extended periods can seriously damage the liver. It’s best to take the lowest dose necessary and stay closer to 3,000 mg per day as your maximum dose. If you need to take high doses of acetaminophen for chronic pain, check with your doctor first.

Can Tylenol Kill You? What’s a Safe Dosage?

Tylenol is an over-the-counter medication used to treat mild to moderate pain and fever. It contains the active ingredient acetaminophen.

Acetaminophen is one of the most common drug ingredients. According to the Food and Drug Administration (FDA), it’s found in more than 600 prescription and non-prescription drugs.

Acetaminophen may be added to medications used to treat a wide variety of conditions, including the following:

• allergies
• arthritis
• backaches
• cold and flu
• headaches
• menstrual cramps
• migraines
• muscle aches
• toothache

In this article, we’ll look at what’s considered a safe dosage, the signs and symptoms that could indicate an overdose, and how to avoid taking too much.

It’s possible to overdose on acetaminophen. This can happen if you take more than the recommended dosage.

When you take a normal dose, it enters your gastrointestinal tract and is absorbed into your bloodstream. It starts to take effect in 45 minutes for most oral forms, or up to 2 hours for suppositories. Eventually, it’s broken down (metabolized) in your liver and excreted in your urine.

Taking too much Tylenol changes the way it’s metabolized in your liver, resulting in an increase in a metabolite (a by-product of metabolism) called N-acetyl-p-benzoquinone imine (NAPQI).

NAPQI is toxic. In the liver, it kills cells and causes irreversible tissue damage. In severe cases, it can cause liver failure. This triggers a chain of reactions that can lead to death.

According to a 2016 literature review, liver failure caused by acetaminophen overdose causes death in approximately 28 percent of cases. Among those who have liver failure, 29 percent require a liver transplant.

Those who survive an acetaminophen overdose without needing a liver transplant may experience long-term liver damage.

Tylenol is relatively safe when you take the recommended dose.

In general, adults can take between 650 milligrams (mg) and 1,000 mg of acetaminophen every 4 to 6 hours. The FDA recommends that an adult shouldn’t take more than 3,000 mg of acetaminophen per day unless directed otherwise by their healthcare professional.

Don’t take Tylenol for more than 10 days in a row unless you’ve been instructed to do so by your doctor.

The chart below contains more detailed dosage information for adults based on the type of product and the amount of acetaminophen per dose.

Product	Acetaminophen	Directions	Maximum dosage	Maximum daily acetaminophen
Tylenol Regular Strength Tablets	325 mg per tablet	Take 2 tablets every 4 to 6 hours.	10 tablets in 24 hours	3,250 mg
Tylenol Extra Strength Caplets	500 mg per caplet	Take 2 caplets every 6 hours.	6 caplets in 24 hours	3,000 mg
Tylenol 8 HR Arthritis Pain (Extended Release)	650 mg per extended-release caplet	Take 2 caplets every 8 hours.	6 caplets in 24 hours	3,900 mg

For children, the dose varies according to weight. If your child is under the age of 2, ask your doctor for the correct dose.

In general, children can take around 7 mg of acetaminophen per pound of their body weight every 6 hours. Children shouldn’t take more than 27 mg of acetaminophen per pound of their weight in 24 hours.

Don’t give your child Tylenol for more than 5 days straight unless you’ve been instructed to do so by your child’s doctor.

Below, you’ll find more detailed dosage charts for children based on different products for infants and children.

The signs and symptoms of a Tylenol overdose include:

• nausea
• vomiting
• loss of appetite
• pain in the upper right side of the abdomen
• high blood pressure

Call 911 or poison control (800-222-1222) right away if you suspect you, your child, or someone you know took too much Tylenol.

It’s critical to seek medical assistance as soon as possible. Early treatment is associated with lower mortality rates in both children and adults.

Treatment for a Tylenol or acetaminophen overdose depends on how much was taken and how much time has passed.

If less than an hour has passed since the Tylenol was ingested, activated charcoal may be used to absorb the remaining acetaminophen from the gastrointestinal tract.

When liver damage is likely, a drug calledN-acetyl cysteine (NAC) may be given orally or intravenously. NAC prevents liver damage caused by the metabolite NAPQI.

Keep in mind, though, that NAC can’t reverse liver damage that has already occurred.

When used as directed, Tylenol is safe for most people. However, you should speak to your healthcare provider before using Tylenol if you have any of the following conditions:

• liver disease or liver failure
• alcohol use disorder
• hepatitis C
• kidney disease
• malnutrition

Tylenol may pose some risks to people who are pregnant or breastfeeding. Be sure to speak to your healthcare provider before taking a Tylenol product.

Tylenol can interact with other medications. It’s important to talk to your doctor or pharmacist before taking Tylenol if you’re also taking any of the following medications:

• anticonvulsant medications, particularly carbamazepine and phenytoin
• blood thinners, particularly warfarin and acenocoumarol
• cancer drugs, particularly imatinib (Gleevec) and pixantrone
• other drugs that contain acetaminophen
• the antiretroviral drug zidovudine
• the diabetes drug lixisenatide
• the tuberculosis antibiotic isoniazid

Overuse of acetaminophen probably happens more often than you think. This is due to acetaminophen being a common ingredient in many types of over-the-counter and prescription drugs.

Acetaminophen overdoses are responsible for approximately 56,000 emergency room visits each year in the United States. Around 50 percent of acetaminophen overdoses are unintentional.

Here are some ways to ensure that you’re taking a safe level of acetaminophen:

• Check product labels. Tylenol is one of many drugs that contain acetaminophen. Carefully check the labels of any drugs you’re taking. Acetaminophen will usually be listed under “active ingredients.” It may be written as APAP or acetam.
• Don’t take more than one product at a time that contains acetaminophen. Taking Tylenol together with other medications, like cold, flu, allergy, or menstrual cramp products, may result in a higher intake of acetaminophen than you realize.
• Be careful when giving Tylenol to children. You shouldn’t give Tylenol to children unless it’s necessary for pain or fever. Don’t give Tylenol with any other products that contain acetaminophen.
• Carefully follow the dosing instructions indicated on the label. Don’t take more than the recommended dose. For children, weight is the most effective way to determine how much to give. If you’re not sure, ask a pharmacist for help figuring out the dose.
• If the maximum dose doesn’t feel like it’s working, don’t take more. Talk to your doctor instead. Your doctor will evaluate whether another drug can help with your symptoms.

If you suspect someone is at risk of using Tylenol to harm themselves or has used Tylenol to harm themselves:

• Call 911 or seek emergency medical attention. Remain with them until help arrives.
• Remove any additional medication.
• Listen without judging or admonishing them.

If you or someone you know is considering suicide, reach out to the Suicide Prevention Lifeline at 800-273-8255 or text HOME to 741741 for help and support.

Tylenol is safe when it’s used according to the directions on the label. Taking too much Tylenol can cause permanent liver damage, liver failure, and, in some cases, death.

Acetaminophen is the active ingredient in Tylenol. Acetaminophen is a common ingredient in many types of over-the-counter and prescription drugs. It’s important to read drug labels carefully as you don’t want to take more than one drug containing acetaminophen at a time.

If you’re not sure if Tylenol is right for you or what’s considered a safe dose for you or your child, reach out to a healthcare professional or pharmacist for advice.

  • Dialysis patients: recommended dose every eight hours, no additional dose required.
• Patients with hepatic impairment : Consult your physician for a reduced dose.

Tylenol for Pets

You should not give Tylenol to your pets except under the direction of a veterinarian. Because animals do not metabolize acetaminophen in the same way that humans do, paracetamol is more toxic to animals and even a small dose can be fatal. In addition to liver damage, acetaminophen can cause methemoglobinemia (putting the animal at risk of heart attack), kidney damage, swelling of the face and paws, and dry eyes.

If your pet is in pain or has a fever, consult your veterinarian for appropriate medication. In rare cases, a veterinarian may give instructions for administering paracetamol to a pet. More often, however, the veterinarian will prescribe a pain reliever or antipyretic that is more appropriate for the animal.

If your pet has accidentally swallowed paracetamol, take it to a veterinary clinic or veterinary hospital immediately. Treatment consists of gastric emptying and supportive care. Severe paracetamol poisoning may require medication or a blood transfusion.

How to take Tylenol

Tylenol is taken by mouth as a tablet or softgel. When taking Tylenol tablets, caplets, or softgels:

• Read the instructions and warnings printed on the package or insert.
• Take two tablets or capsules with a full glass of water.
• Tylenol can be taken with food or on an empty stomach.

When taking or using Tylenol, you can consider the following safety tips:

• Always check the expiration date. If the medicine has expired, dispose of it safely and buy a new vial.
• Always check the instructions for the correct dose and schedule. Tylenol products of different strengths have different doses and dosing regimens, so do not assume that the directions on one Tylenol product apply to other Tylenol products or generic acetaminophen products.
• To prevent paracetamol overdose or poisoning, check all other medicines you take to make sure they do not contain paracetamol. When taking Tylenol not take any other paracetamol products.
• You can stop taking Tylenol if you regularly drink three or more alcoholic drinks a day. Regular alcohol consumption can increase the toxicity of paracetamol in the liver.
• To avoid unintentional overdose, keep a medication diary or use the app to record when you take each dose. Do not take another dose until the appropriate time.
• When taking a tablet or capsule, try not to lie down for at least half an hour to allow the tablet to pass through the esophagus.

Tylenol Dosage FAQ

How long does Tylenol last?

Tylenol takes about 30 to 45 minutes to start working and reach maximum effect in 60 to 90 minutes.

How long does Tylenol stay in your body?

At the recommended dosage, Tylenol should last four to six hours. By eight o’clock, only a small amount of acetaminophen remains in the bloodstream.

Paracetamol is rapidly eliminated from the body by chemically converting it into other substances (metabolites). The rate at which the body eliminates acetaminophen is measured by its half-life of , the amount of time it takes for the body to metabolize half the amount of paracetamol in the body. The half-life of paracetamol is usually between one and three hours. However, in people with liver problems or paracetamol overdoses, the half-life of paracetamol can be up to eight hours or longer.

What happens if I miss my Tylenol?

Missing a dose of Tylenol is not a problem. The missed dose can be taken at any time provided that the next dose is not taken within at least four hours. Do not take an extra dose to make up for a missed dose.

How do I stop taking Tylenol?

If you take paracetamol at the recommended doses for a limited time, you can easily stop taking paracetamol. Adults and teenagers 12 years of age and older should never take acetaminophen daily for more than 10 days. Children should not take paracetamol daily for more than five days.

Acetaminophen is not addictive. However, large doses may cause unwanted side effects or liver damage. Acetaminophen should not be used for a long time without the advice of a doctor.

Stop using Tylenol if pain gets worse or persists for more than 10 days. If the fever persists for more than three days or rises above 103 degrees Fahrenheit, seek medical attention. Also, stop using Tylenol and seek immediate medical attention for any signs of an allergic skin reaction such as redness, swelling, rash, purple skin, or difficulty breathing.

What can be used instead of Tylenol?

If you need to stop taking Tylenol or are unable to take it due to side effects, allergies, or other reasons, consider alternative over-the-counter analgesics and antipyretics such as aspirin, ibuprofen (Motrin, Advil), or naproxen (Aleve). Talk to your doctor about alternative Tylenol options.

RELATED: How safe is it to take ibuprofen and Tylenol together?

What is the maximum dosage of Tylenol?

Because acetaminophen damages the liver, the maximum daily dose of paracetamol should not exceed 4 grams (4000 milligrams). However, the Tylenol manufacturer and the FDA have set the maximum daily dose of Tylenol at 3 grams (3,000 milligrams). This provides a safe window to prevent accidental or unintentional overdose of acetaminophen.

What interacts with Tylenol?

An overdose of acetaminophen can cause liver damage. Acetaminophen poisoning kills over 500 people in the United States each year and is one of the leading causes of liver transplants. Do not take other medicines containing acetaminophen. while taking Tylenol . Check all your medications carefully. Several combination medicines for colds, flu, sinuses, and arthritis contain paracetamol. The use of one or more of these drugs greatly increases the risk of paracetamol overdose or poisoning.

Other medicines may change the effectiveness of paracetamol or increase the risk of paracetamol liver damage. These medications include alcohol, anesthetics, barbiturates, nicotine, some types of antibiotics, and some anticonvulsants. Talk to your doctor about other possible drug interactions with Tylenol.

Food does not affect the body’s ability to absorb paracetamol. However, cruciferous vegetables – cabbage, broccoli, cauliflower, kale, Brussels sprouts, bok choy, radish, turnip, rutabaga, arugula, kale greens, and similar foods – can speed up the metabolism of acetaminophen in the body, shortening its duration and effectiveness.

Tylenol is an over-the-counter drug used to treat mild to moderate pain and fever. It contains the active ingredient acetaminophen.

Acetaminophen is one of the most common drug ingredients. According to the Food and Drug Administration (FDA), it is found in more than 600 prescription and over-the-counter products.

Acetaminophen can be added to medicines used to treat a wide variety of conditions, including the following:

• allergies
• arthritis
• back pain
• colds and flu
• headaches
• menstrual cramps
• migraines

• toothache

In this article, we will look at what is considered a safe dosage, signs and symptoms that may indicate an overdose, and how not to take too much.

Is it possible to overdose Tylenol?

Possible overdose of acetaminophen. This can happen if you take more than the recommended dose.

When you take the usual dose, it enters the gastrointestinal tract and is absorbed into the blood. It starts working in 45 minutes for most oral forms or up to 2 hours for suppositories. Eventually, it is broken down (metabolized) in the liver and excreted in the urine.

Taking too much Tylenol changes the way it is metabolized in the liver, leading to an increase in a metabolite (metabolic by-product) called N-acetyl-p-benzoquinone imine (NAPQI).

NAPQI is toxic. In the liver, it kills cells and causes irreversible tissue damage. In severe cases, this can lead to liver failure. This sets off a chain of reactions that can lead to death.

According to a 2016 literature review, liver failure caused by acetaminophen overdose results in death in about 28 percent of cases. Among those with liver failure, 29% are in need of a liver transplant.

Those who survive an acetaminophen overdose without a liver transplant may experience long-term liver damage.

What is the safe dosage?

Tylenol is relatively safe when you take the recommended dose.

Generally, adults can take 650 milligrams (mg) to 1,000 mg of acetaminophen every 4 to 6 hours. The FDA recommends that an adult not take more than 3,000 mg of acetaminophen per day unless directed otherwise by a physician.

Do not take Tylenol for more than 10 days in a row unless directed by a doctor.

The table below provides more detailed adult dosage information based on product type and amount of acetaminophen per dose.

Tylenol 8 HR for arthritis pain (extended release)	650 mg per extended release capsule	Take 2 capsules every 8 hours.	6 capsules in 24 hours	3.900 mg

For children, the dose varies according to weight. If your child is under 2 years of age, ask your doctor for the correct dose.

Typically, children can take about 7 mg of acetaminophen per pound of body weight every 6 hours. Children should not take more than 27 mg of acetaminophen per pound of their body weight in a 24 hour period.

Do not give your child Tylenol for more than 5 consecutive days unless you have been instructed to do so by your child’s doctor.

What are the signs and symptoms of a Tylenol overdose?

Signs and symptoms of a Tylenol overdose include:

• nausea
• vomiting
• loss of appetite
• upper right abdominal pain
• high blood pressure

Call 911 or a poison control center (800-222-1222) immediately if you suspect that you, your child, or someone you know has taken too much Tylenol.

It is very important to seek medical attention as soon as possible. Early treatment is associated with low mortality in both children and adults.

How is an overdose treated?

Tylenol or acetaminophen overdose treatment depends on how much time has been taken and how much time has passed.

If less than an hour has passed since taking Tylenol, activated charcoal can be used to absorb any remaining acetaminophen from the gastrointestinal tract.

If liver damage is likely, a drug called N-acetylcysteine ​​(NAC) can be given orally or intravenously. NAC prevents liver damage caused by the NAPQI metabolite.

Be aware, however, that NAC cannot reverse liver damage that has already occurred.

Who should not take Tylenol?

When used as directed, Tylenol is safe for most people. However, you should talk to your healthcare provider before using Tylenol if you have any of the following conditions:

• liver disease or liver failure
• alcohol use disorder
• hepatitis C
• kidney disease
• malnutrition

Tylenol may pose some risk to pregnant or breastfeeding individuals. Be sure to talk to your healthcare provider before taking a Tylenol product.

Tylenol may interact with other medicines. It is important to talk to your doctor or pharmacist before taking Tylenol if you are also taking any of the following medicines:

• anticonvulsants, especially carbamazepine and phenytoin
• blood thinners, especially warfarin and acenocoumarol
• anticancer drugs, especially imatinib (gliv ec) and pixantrone
• other drugs containing acetaminophen
• antiretroviral drug zidovudine
• lixisenatide, a diabetes medicine
• anti-tuberculosis antibiotic isoniazid

Overdose prevention

Acetaminophen abuse is probably more common than you think. This is because acetaminophen is a common ingredient in many over-the-counter and prescription drugs.

Acetaminophen overdose causes approximately 56,000 emergency room visits each year in the United States. About 50 percent of acetaminophen overdose cases are unintentional.

Here are a few ways to make sure you’re taking safe levels of acetaminophen:

• Check product labels. Tylenol is one of many products containing acetaminophen. Check the labels of any medications you take carefully. Acetaminophen is usually listed under “active ingredients”. It can be written as APAR or Acetam.
• Do not take more than one product containing acetaminophen at the same time. Taking Tylenol along with other medications such as colds, flu, allergies, or menstrual cramps may result in higher acetaminophen intake than you might think.
• Be careful when giving Tylenol to children. You should not give Tylenol to children unless it is needed for pain or fever. Do not give Tylenol with other products containing acetaminophen.
• Carefully follow the dosage instructions on the label. Do not take more than the recommended dose. For children, weight is the most effective way to determine how much to give. If you are not sure, ask your pharmacist for help in determining the dose.
• If the maximum dose does not work, do not take more. Talk to your doctor instead. Your doctor will evaluate whether another drug can help your symptoms.

If you suspect someone is at risk of using Tylenol to harm themselves or has used Tylenol to harm themselves:

• Call 911 or seek emergency medical attention. Stay with them until help arrives.
• Remove any additional medications.
• Listen without judging or rebuking them.

If you or someone you know is thinking about suicide, call the Suicide Prevention Helpline at 800-273-8255 or text HOME at 741741 for help and support.

Bottom line

Tylenol is safe when used according to label directions. Taking too much Tylenol can cause permanent liver damage, liver failure and, in some cases, death.

Acetaminophen is the active ingredient in Tylenol. Acetaminophen is a common ingredient in many over-the-counter and prescription drugs.
