Questions about ZYRTEC®

Do you have questions about ZYRTEC® Usage Guidelines and COVID-19 Outbreak?

Please click here for more information.

What is ZYRTEC®?

ZYRTEC® is an over-the-counter medicine that provides effective, 24-hour relief of indoor and outdoor allergy symptoms.

What allergy symptoms does ZYRTEC® relieve?

ZYRTEC® relieves your worst allergy symptoms of sneezing, runny nose, itchy, watery eyes, and itchy nose or throat.

Is ZYRTEC® an antihistamine?

Yes. ZYRTEC® contains cetirizine HCl, which is an antihistamine.

What is an antihistamine?

An antihistamine is a drug that blocks the action of histamine—an allergy-causing chemical that’s released by certain cells in the body. Antihistamines are used to treat runny nose, sneezing and other allergy symptoms.

Should I take ZYRTEC® with food?

Your choice. ZYRTEC® can be taken either with or without food.

How fast does ZYRTEC® start working?

ZYRTEC® begins to work at hour 1 on the first day you take it.

How long does ZYRTEC® last?

ZYRTEC® provides 24-hour relief, all day and all night.

Is it okay to take ZYRTEC® over a long period of time?

The ZYRTEC® package label doesn’t state a limit on how long you can take ZYRTEC®. Talk to your doctor if you have any questions, especially if you’re taking other medicines or being treated for any other conditions.

What’s the best time of day to take ZYRTEC®?

Any time of day works. And ZYRTEC® will continue to work for 24 hours.

Do I need a prescription to take ZYRTEC®?

No. Since 2008, ZYRTEC® has been available over the counter, without a prescription.

Is the over-the-counter version of ZYRTEC® the same as the prescription strength?

Yes. Today’s ZYRTEC® has the same exact strength as the version that required a prescription previously.

Can ZYRTEC® make me drowsy?

For information on side effects, please read the ZYRTEC® product label or review the product details on this site.

Can I use ZYRTEC® if it is expired?

No. If your ZYRTEC® has expired, please discard it properly and get a new package. (See next question.)

What is the proper way to dispose of unused or expired ZYRTEC® products?

Do NOT dispose of any ZYRTEC® product by emptying it into your sink, toilet or storm drain. Check to see if your pharmacy or community has a take-back program in which you can drop off your expired or unused medicine for them to dispose for you. Otherwise, place your medicine in an unmarked, sealed container and dispose of the container in your household trash. Visit the FDA website for more information.

Questions about ZYRTEC® Dissolve Tabs

Do dissolve tabs work faster than tablets or liquid gels?

ZYRTEC® Dissolve Tabs provide the same fast relief as ZYRTEC® Tablets and ZYRTEC® Liquid Gels. All ZYRTEC® medicines start working at hour 1 on the first day you take it.

Can I chew or swallow the dissolve tabs? Or do they need to dissolve on my tongue first?

ZYRTEC® Dissolve Tabs are designed to dissolve in your mouth without chewing or drinking water, but it’s perfectly fine to chew or swallow them.

Questions about ZYRTEC-D®

How is ZYRTEC-D® different from ZYRTEC®?

ZYRTEC-D® contains pseudoephedrine, which relieves nasal congestion. So it relieves all the same symptoms as ZYRTEC®, plus it also has a powerful decongestant. For more, see: “What symptoms does ZYRTEC® relieve?”

How does ZYRTEC-D® work on sinus pressure and congestion?

ZYRTEC-D® contains a nasal decongestant that narrows the blood vessels in the nose and sinus region, which shrinks the tissue in that area to allow air and mucus to flow normally.

Why is ZYRTEC-D® located behind the pharmacy counter?

Pseudoephedrine, an active ingredient in some cold, allergy, and sinus products, can be chemically processed into methamphetamine (commonly known as meth). The illegal use of meth had increased, prompting Congress to pass the Combat Methamphetamine Epidemic Act of 2006 (CEMA). The objective of the law is to eliminate the use of pseudoephedrine in the illegal production of meth. By law, products containing pseudoephedrine must now be sold behind the counter and through online retailers who must meet certain requirements.

Note that products containing pseudoephedrine remain available without a prescription in most states.

Questions about Children’s ZYRTEC®

How can I be sure I’m giving my child the proper dose of Children’s ZYRTEC®?

Always follow the instructions that come with Children’s ZYRTEC®. When taking Children’s ZYRTEC® Allergy Syrup, be sure to use the dosing cup that comes in the package. Other items like kitchen teaspoons, droppers or measuring devices that come with other medicines may not be accurate. If you have any questions about treating your child’s allergies, please speak with your doctor.

Can Children’s ZYRTEC® make my child drowsy?

For information on side effects, please read the Children’s ZYRTEC® product label or review the product details on this site.

What’s the difference between Children’s ZYRTEC® Allergy Syrup and Children’s ZYRTEC® Dissolve Tabs?

Children’s ZYRTEC® Allergy Syrup can be taken by kids 2 years and older, whereas Children’s ZYRTEC® Dissolve Tabs is for ages 6 and up.

What’s the difference between ZYRTEC® Dissolve Tabs and Children’s ZYRTEC® Dissolve Tabs?

There is no difference. Both products contain 10mg of cetirizine in the same citrus flavor and can be taken by both adults and children 6 years and older.

General Allergy Questions

How do I know if I have allergies?

If you find yourself sneezing a lot or have a consistently runny or stuffy nose, there’s a good chance you have upper respiratory allergies. Allergies affect more than 50 million people in the United States alone.

What are the common symptoms of upper respiratory allergies?

People with allergies can experience lots of symptoms, including sneezing, runny nose, stuffy nose (nasal congestion), or itchy, watery eyes.

What are outdoor allergies?

If you only develop upper respiratory symptoms at certain times of the year (often spring or fall), you probably have seasonal allergic rhinitis, or outdoor allergies. These allergies can be triggered by trees, grass and weed pollens, or outdoor mold. Learn more about outdoor allergies.

What are indoor allergies?

If you have symptoms all year round, it’s likely perennial allergic rhinitis, or indoor allergies. Common triggers include animal dander (tiny skin flakes or saliva from animals), indoor mold and dust mites. Learn more about indoor allergies.

What can I do to help relieve my outdoor allergies?

In addition to taking ZYRTEC®, you may want to:

Keep your windows closed and use air conditioning instead
Stay indoors during peak pollen hours (5 a.m. – 10 a.m.)
Change your clothes after you’ve been outside
Don’t hang your laundry outside to dry
Avoid mowing the lawn or raking leaves
Learn more outdoor allergy relief tips.

What can I do to help relieve my indoor allergies?

In addition to taking ZYRTEC®, you may want to:

Clean the filters in your air conditioner and heater regularly
Vacuum often, especially carpets and upholstered furniture
Keep your pets bathed and groomed
Run an air purifier
Crack open the bathroom window during showers
Learn more about indoor allergies.

Printing Coupons

What is SmartSource?

SmartSource is an online network of coupons and offers that can help you save money. Just download the coupons you want and print them out to use at your favorite stores.

Why do I need Adobe Reader?

With SmartSource’s new print technology, we use Adobe PDF Security. Most people already have Adobe Reader installed, so this makes the transition seamless. And while many programs can open PDF files, SmartSource coupons rely on security technologies unique to Adobe Reader.
You can get Adobe Reader for free here.

Can I print coupons more than once?

You generally get one chance to print your coupons and offers, so make sure your printer is turned on and working when you’re ready to print. But if something goes wrong, you get one more try. Also, if the total number of available offers has been claimed, the offer can expire and may not be printed. This can be the case with popular items.

A Message says I already printed offers that I didn’t?

SmartSource coupons usually have a print limit of 2 times on any one computer. If you share a computer with other users, they could have used those prints already. Also, offers can expire if the total number that the manufacturer made available has been met. This can be the case with popular items.

The screen said my coupons were printing,but they never did

Check to verify that your printer is connected and turned on.
If you were trying to print several coupons, the file size may be exceeding the amount of memory you have available. Try printing a single coupon. If that works, you may not be able to print out all that you want in a single session.
If you share a computer with other people, make sure they did not print the coupon already. Since SmartSource coupons can only be printed up to 2 times on the same computer, you may have exceeded the number of print times.

Zyrtec: 7 things you should know

Medically reviewed by Carmen Fookes, BPharm. Last updated on April 8, 2020.

1. How it works

Zyrtec is a brand (trade) name for cetirizine. Cetirizine is an antihistamine that works selectively on peripheral histamine-1 (H-1) receptors (these are histamine receptors that are located outside of the brain and spinal cord). Because it acts on peripheral histamine receptors, cetirizine is much less likely to cause drowsiness compared with some older antihistamines.
Histamine is a chemical that is released by mast cells in response to an allergen, and it is responsible for many of the symptoms of an allergic reaction, such as swelling of the mucous membranes, sneezing, and itching. Zyrtec binds to histamine receptors and prevents histamine from having an effect on those receptors, which reduces the symptoms of an allergic reaction.
Zyrtec belongs to the group of drugs known as antihistamines. Zyrtec may also be called an h2-antihistamine, a second-generation antihistamine, or a nonsedating antihistamine.

2. Upsides

Used to treat allergic-type reactions due to perennial or seasonal allergic rhinitis (hay fever).
Effective at controlling symptoms such as sneezing, itching, watery eyes, and runny nose that occur as a result of other respiratory allergens.
Can provide relief from itching that occurs as a result of chronic urticaria (hives). Symptoms of hives include raised, red, itchy bumps, streaks, or blotches on the skin.
May be used in the treatment of allergic conjunctivitis, insect bites, and other allergic skin disorders.
Is less likely to cause sedation than older antihistamines.
Can be taken once a day.
May be given daily on a regular basis when allergens are most prevalent (such as during spring or summer).
Zyrtec does not appear to interact with many drugs (theophylline slightly decreased the clearance of Zyrtec).
Zyrtec has been demonstrated to be safe in children older than 6 months.
No dosage adjustment is required in liver disease.
Available over-the-counter.
Zyrtec is available as a generic under the name of cetirizine.

3. Downsides

If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:

A headache, sore throat, abdominal pain, fatigue, drowsiness, or coughing. Other side effects are uncommon.
Generally does not cause drowsiness, although more likely to do so at higher dosages. Caution should be exercised before driving or operating machinery until full effects of Zyrtec are known.
The dosage of Zyrtec should be reduced in kidney disease and caution should be exercised when Zyrtec is used in people with seizure disorders.
Zyrtec, like all other antihistamines, may decrease the response to skin prick tests. Discontinue Zyrtec at least 72 hours prior to skin testing.

Note: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects. View complete list of side effects

4. Bottom Line

Zyrtec is an antihistamine that effectively treats allergic-type reactions such as hay fever or skin reactions caused by insect bites. Although drowsiness with Zyrtec is uncommon, Zyrtec is more likely than loratadine to cause drowsiness.

5. Tips

May be taken with or without food. Zyrtec is usually taken once a day. During the pollen season, your doctor may advise you to take it every day if you suffer from seasonal allergic rhinitis.
Although Zyrtec is unlikely to make you drowsy, some people are susceptible to this effect, especially if they are taking dosages at the upper end of the recommended dosage range. Do not drive or operate machinery if Zyrtec makes you drowsy. Alcohol and other sedative-like drugs may cause additional reductions in alertness if used with Zyrtec.
Seek urgent medical advice if you have hives and develop swelling of the face, throat, or tongue, dizziness, drooling, difficulty speaking, or shortness of breath.
Zyrtec is not a substitute for epinephrine which is used for the treatment of severe allergies and anaphylaxis.
Zyrtec is available as a tablet, chewable tablet, or a suspension for adults or children who have difficulty swallowing tablets.
See your doctor if your mild allergy symptoms have not improved after three days of treatment with Zyrtec, or if your hives persist for more than six weeks despite taking Zyrtec.
Discontinue Zyrtec once your allergy symptoms have resolved.
Do not take Zyrtec during pregnancy or while breastfeeding unless on the advice of your doctor.

6. Response and Effectiveness

Peak concentrations are reached within one hour of administration of Zyrtec tablets or syrup. The onset of effect occurs within 20 minutes in 50% of people and within an hour in 95%.
Effects persist for at least 24 hours following a single dose of Zyrtec. No tolerance has been found to Zyrtec’s antihistaminic effect. Once discontinued, the skin recovers its normal reactivity to histamine within three days.
Taking 10mg of Zyrtec is more effective than taking 5mg; taking 20mg appears not to provide any additional effect.
Food has no effect on the overall absorption of Zyrtec; however, it may increase the time it takes for peak levels of Zyrtec to be reached in the blood.

7. Interactions

Medicines that interact with Zyrtec may either decrease its effect, affect how long it works for, increase side effects, or have less of an effect when taken with Zyrtec. An interaction between two medications does not always mean that you must stop taking one of the medications; however, sometimes it does. Speak to your doctor about how drug interactions should be managed.

Common medications that may interact with Zyrtec include:

anticonvulsants, such as fosphenytoin, lamotrigine, levetiracetam, phenytoin, or valproic acid
antidepressants, such as clomipramine, escitalopram, or fluvoxamine
antipsychotics, such as aripiprazole, chlorpromazine, or clozapine
baclofen
barbituates, such as butabarbital
benzodiazepines, such as diazepam or temazepam
benztropine
bupropion
buspirone
cannabis and cannabinoids
clonidine
HIV medications such as darunavir, lopinavir, ritonavir, or saquinavir
duloxetine
ketamine
lithium
monoamine oxidase antidepressants, such as phenelzine, isocarboxazid
mumps skin test antigen
opioids, such as codeine, fentanyl, hydrocodone
other antihistamines, such as azatadine, azelastine, or brompheniramine
sleeping medications, such as zolpidem
St John’s wort
topiramate
voriconazole.

Alcohol may increase the risk of sedation with Zyrtec.

Note that this list is not all-inclusive and includes only common medications that may interact with Zyrtec. You should refer to the prescribing information for Zyrtec for a complete list of interactions.

Cetirizine: antihistamine that relieves allergy symptoms

If you or your child have been prescribed cetirizine, follow your doctor’s instructions about how and when to take it.

If you bought cetirizine from a pharmacy or shop, follow the instructions that come with the packet.

How much to take

Cetirizine comes as tablets and capsules (10mg) and as a liquid medicine (labelled either 5mg/ml or 1mg/1ml).

The usual dose in adults is 10mg once daily.

Doses are usually lower for people with kidney problems.

For children, your doctor will use your child’s weight or age to work out the right dose.

If you have bought cetirizine for a child, follow the instructions on the packet.

Depending on their age, children may take cetirizine twice a day. In this case, try to space the doses 10 to 12 hours apart.

How to take it

You can take cetirizine with or without food.

Always take cetirizine tablets or capsules with a drink of water, milk or juice. Swallow them whole. Do not chew them.

Cetirizine liquid may be easier for children to take than tablets or capsules. The liquid medicine will come with a plastic syringe or spoon to help you measure out the right dose.

If you don’t have a syringe or spoon, ask your pharmacist for one. Do not use a kitchen teaspoon as it will not give the right amount.

When to take it

You may only need to take cetirizine on a day you have symptoms – for example, if you have been exposed to a trigger like animal hair.

Or you may need to take it regularly to prevent symptoms – for example, to stop hay fever during spring and summer.

What if I forget to take it?

Take your forgotten dose as soon as you remember, unless it’s nearly time for your next dose. Do not take a double dose to make up for a forgotten dose.

If you forget to give a dose to a child who is taking cetirizine twice a day, you can give the dose if it’s within 4 hours of when they should have had it.

If you remember more than 4 hours after, do not give the missed dose. Instead, wait until the next dose and carry on as normal.

If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.

What if I take too much?

Cetirizine is generally very safe. Taking too much is unlikely to harm you or your child.

If you take an extra dose by mistake, you might get some of the common side effects.

If this happens or you’re concerned, contact your doctor.

Differences, similarities, and which is better for you

While browsing the allergy section at your local pharmacy, you may have come across Zyrtec and Zyrtec-D. Despite their names, Zyrtec and Zyrtec-D are not the same drug. They both contain cetirizine hydrochloride, which is used to treat allergy symptoms like sneezing, watery eyes, and an itchy, runny nose. However, Zyrtec-D has an added decongestant.

Zyrtec is classified as an oral antihistamine. Compared to Benadryl (diphenhydramine) and other first-generation antihistamines, Zyrtec causes less drowsiness. The main active ingredient in Zyrtec works by blocking histamine receptors to prevent the effects of histamine. Histamine is a chemical that is produced by the body when it’s exposed to allergens like pet dander and dust mites.

Zyrtec and Zyrtec-D are similar allergy medications, but there are some important differences to consider.

What are the main differences between Zyrtec and Zyrtec-D?

The main difference between Zyrtec and Zyrtec-D is that Zyrtec-D contains the decongestant pseudoephedrine. Also known by its brand name, Sudafed, pseudoephedrine works by shrinking blood vessels to reduce swelling and congestion in the nasal passages.

Zyrtec is the brand name for cetirizine. It is available as an oral syrup, orally disintegrating (ODT) tablet and oral tablet. Children aged 2 to 6 years old can be given the oral syrup. Zyrtec tablets can be administered to children, adolescents, and adults 6 years and older. Zyrtec can be purchased over the counter.

Zyrtec-D contains cetirizine and pseudoephedrine. It is only available as an oral tablet for adults and children 12 years and older. While Zyrtec can be found in the pharmacy aisles, Zyrtec-D is usually stored behind the counter at the pharmacy. This is because there are restrictions on how much pseudoephedrine can be sold to a person at a given time.

Main differences between Zyrtec and Zyrtec-D
Drug class	Second-generation antihistamine	Second-generation antihistamine
Brand/generic status	Brand and generic version available	Brand and generic version available
What is the generic name?	Cetirizine	Cetirizine-Pseudoephedrine
What form(s) does the drug come in?	Oral tablet Orally disintegrating tablet Oral syrup	Oral tablet
What is the standard dosage?	One 5 mg or 10 mg tablet once daily	One 5 mg-120 mg tablet twice daily
How long is the typical treatment?	As needed for seasonal or perennial allergies	As needed for seasonal or perennial allergies. Pseudoephedrine use should be limited to no more than 10 days.
Who typically uses the medication?	Adults and children 2 years and older	Adults and children 12 years and older

Conditions treated by Zyrtec and Zyrtec-D

Zyrtec and Zyrtec-D are both FDA-approved to treat allergic rhinitis, also known as hay fever. Both drugs are primarily indicated for seasonal allergic rhinitis, which causes symptoms such as runny nose and sneezing. Both drugs can also treat other symptoms of seasonal allergies such as itchy, watery eyes (allergic conjunctivitis).

Zyrtec is FDA approved to treat hives, or chronic urticaria. Allergic reactions on the skin can often manifest as hives and itching. Because Zyrtec-D contains a nasal decongestant, regular Zyrtec is used for skin reactions.

Allergic rhinitis	Yes	Yes
Hives	Yes	No

Is Zyrtec or Zyrtec-D more effective?

For general symptoms of allergic rhinitis, such as sneezing and watery eyes, Zyrtec and Zyrtec-D are similarly effective. For a stuffy nose, or nasal congestion, Zyrtec-D would be more effective because of the added decongestant.

In a double-blind, clinical study, cetirizine was found to significantly improve symptoms of perennial allergic rhinitis. The study measured symptom improvement by total symptom severity complex (TSSC) and a questionnaire for four weeks. Compared to placebo, cetirizine significantly improved nasal symptoms after the first week (p<0.05).

Another randomized, controlled trial compared cetirizine with other antihistamines, such as fexofenadine and desloratadine. The study looked at 150 patients’ response to antihistamines with a skin prick test. Results found that the antihistamines showed similar effectiveness.

Consult your doctor or pharmacist on allergy medications that may be best for you. Your healthcare provider can give you medical advice on what to take. They may even recommend another antihistamine like Claritin or Allegra instead of Zyrtec for your symptoms.

Coverage and cost comparison of Zyrtec vs. Zyrtec-D

Zyrtec is an over-the-counter medicine that isn’t generally covered by Medicare and insurance plans. In some cases, it may be covered with a prescription from a doctor. The average retail price of Zyrtec is around $15 to $20, depending on tablet strength and quantity. SingleCare offers a Zyrtec coupon card that can lower this price to as little as $3.

Most Medicare and insurance plans won’t cover Zyrtec-D because, like other oral antihistamines, it’s found over the counter. The average retail cost is around $30 to $50 depending on the number of tablets. If you have a prescription you can use a SingleCare discount card for Zyrtec-D to save more and bring the cost down to $10 for 12-hour tablets. Check with your pharmacy to see if they accept discount cards.

Typically covered by insurance?	No	No
Typically covered by Medicare Part D?	No	No
Standard dosage	One 10 mg tablet once daily (quantity of 30)	One 5 mg-120 mg tablet twice daily (quantity of 24)
Typical Medicare copay	Depends on your insurance plan	Depends on your insurance plan
SingleCare cost	$3–$4	$10

Common side effects of Zyrtec vs. Zyrtec-D

The most common side effects of Zyrtec are drowsiness, headache, dizziness, and fatigue. Other side effects may include a dry mouth, cough, and sore throat.

Zyrtec-D shares similar side effects with Zyrtec because it contains cetirizine. However, since it also contains pseudoephedrine, other side effects may include insomnia, heart palpitations, and nervousness or anxiety.

Drug interactions of Zyrtec vs. Zyrtec-D

Certain drugs should be avoided with Zyrtec or Zyrtec-D when possible. Some drugs have CNS depressant side effects that result in increased drowsiness with Zyrtec. Opioids, such as hydrocodone or oxycodone, can cause increased drowsiness and sedation when taken with Zyrtec.

Tricyclic antidepressants can also cause increased drowsiness with Zyrtec. Antidepressants may also worsen anticholinergic side effects like dry mouth. Other drugs with similar effects include anticonvulsants and muscle relaxants, among others.

Zyrtec and Zyrtec-D should not be used within two weeks of using a monoamine oxidase (MAO) inhibitor. Combining MAO inhibitors with cetirizine can cause increased adverse effects of the antihistamine. Pseudoephedrine in Zyrtec-D can also interact with MAO inhibitors, which could lead to dangerously high blood pressure.

Warnings of Zyrtec and Zyrtec-D

Cetirizine can cause drowsiness and affect your mental alertness. Avoid operating any machinery or driving an automobile while taking cetirizine as it can make you feel drowsy.

Pseudoephedrine stimulates the sympathetic nervous system and can raise blood pressure. While pseudoephedrine is generally safe, its use may increase the risk of abnormal heart rhythms, heart attack, and stroke, especially if you have other cardiovascular conditions like heart disease or diabetes. Those with known coronary heart disease, high blood pressure, or a history of stroke should use caution.

Cetirizine is processed through the liver and kidneys. In those with kidney disease or liver problems, cetirizine use should be monitored or avoided. The risk of adverse effects may be increased in the elderly, who are more prone to kidney or liver problems.

Frequently asked questions about Zyrtec vs. Zyrtec-D

Are Zyrtec and Zyrtec-D the same? / Is Zyrtec or Zyrtec-D better?

Zyrtec and Zyrtec-D are not the same drug. Although they can both be used for allergy relief, one contains a decongestant and the other does not. Zyrtec-D contains pseudoephedrine, a decongestant that can help relieve nasal congestion. If one of your primary symptoms is a stuffy nose, Zyrtec-D may be a better option than regular Zyrtec.

Can I use Zyrtec or Zyrtec-D while pregnant?

Zyrtec is generally safe for use during pregnancy. Zyrtec-D contains pseudoephedrine, which is not recommended during the first trimester or while breastfeeding. Pseudoephedrine can pass through breast milk. Although the risk of birth defects may be low, it’s best to use caution. Consult your doctor for the best allergy medicine to take while pregnant.

Can I use Zyrtec or Zyrtec-D with alcohol?

Drinking alcohol in moderation may not be a life-threatening concern with the occasional use of Zyrtec. Because alcohol can cause CNS depression, you may want to avoid drinking alcohol while on Zyrtec or Zyrtec-D because of the increased risk of drowsiness and sedation.

What is Zyrtec-D good for?

Zyrtec-D is good for symptoms of allergic rhinitis. Because it contains a decongestant, Zyrtec-D is especially good for sinus congestion. Zyrtec-D can also relieve itchy, watery eyes, and a runny nose.

When should I take Zyrtec-D?

Zyrtec-D can be taken at any time of the day. Those who experience drowsiness after taking Zyrtec-D may want to take it in the evening. Zyrtec-D also contains pseudoephedrine, which, on its own, is known to cause trouble sleeping.

Is Zyrtec-D safe to take every day?

Zyrtec-D is recommended for short-term use only. Zyrtec-D contains pseudoephedrine which should not be taken for more than 10 days at a time. If you find yourself needing Zyrtec-D for long-term nasal congestion, consult your healthcare provider.

Is Zyrtec-D good for a sinus infection?

Zyrtec-D is designed for treating allergy symptoms. Because symptoms of sinus infections and allergic rhinitis can overlap, Zyrtec-D may be useful for sinus infections if you’re also experiencing allergies. The pseudoephedrine in Zyrtec-D is a decongestant that can relieve nasal congestion. However, antihistamines are not generally recommended for sinus infections because they can dry out the nasal passages.

How quickly does Zyrtec-D work?

Most people experience relief from Zyrtec-D within an hour. It can take up to two hours for the drug to reach maximum levels in the body. Zyrtec-D lasts for approximately 12 hours and it’s usually taken twice daily for complete relief.

How Often Can You Take Zyrtec (Cetirizine).

Dec 05, 2017

Enqui asked

How frequently can I take Zyrtec (cetirizine)?

Answer

Zyrtec (certirizine) is a second generation antihistamine that is dosed once daily (every 24 hours). There are a few situations where twice daily dosing has been used in children which is discussed below.

Zyrtec is most commonly used to treat urticaria, allergic rhinitis, allergies from mold, pets, dust, seasonal allergies from pollen and grasses, as well as post nasal drip. It comes in a variety of dosage forms including tablets, liquid gels, dissolvable tablets, and a solution.

Dosing Recommendations For Zyrtec

Adults

Zyrtec 5 mg to 10 mg once daily based on severity of allergy symptoms.

Geriatric

Zyrtec 5 mg to 10 mg once daily. In those over 77 years of age, 5 mg is recommended to avoid side effects and the risk of falls.

Children 6 Years Old & Over

Zyrtec 5 mg to 10 mg once daily. There have been studies that suggest taking 5 mg twice daily (every 12 hours) may be more effective than one 10 mg dose to maintain symptom control for some patients.

Children 2 Years Old To 5 Years Old

Zyrtec 2.5 mg once or twice daily, or 5 mg once daily. Similar to the dosing mentioned above, studies show that twice daily dosing may provide better symptoms control.

Infatnts & Toddlers Aged 6 Months To 2 Years Old

Zyrtec 2.5 mg once every daily. For children 12 months and older, they can potentially be given 2. 5mg twice daily.

Overall, Zyrtec is most often often dosed once daily, especially in adults. Children doses range from once to twice daily. If you are experiencing continuous symptoms of allergy, itchy eyes/nose, postnasal drip or congestion, it may be time to see a doctor. He or she may prescribe a nasal steroid for better relief. Zyrtec is generally a safe medication but always consult your doctor first before starting new medications.

Lastly, we want to mention that off-label doses of Zyrtec are sometimes used for resistant cases of uticarta (itching). Studies suggest that 20 mg in adults (10 mg tablet twice daily) is effective and safe to use in certain cases.

Zyrtec for children – Children Mail.ru

Photobank Lori

When is Zyrtec used for children?

The drug is prescribed for allergies to children from the age of six months. The disease can manifest itself as a rash (including hives), runny nose (rhinitis), itchy eyes, bronchospasm, tissue edema.

What substance is included in Zyrtek and how does it work?

The active substance of Zirtek is cetirizine. With allergies, the body’s immune cells secrete a substance called histamine, which causes symptoms – itching, swelling, redness.To do this, histamine needs to bind to receptor proteins on cells.

Cetirizine blocks histamine receptors, which means that allergy symptoms do not develop. Of course, it is usually not possible to completely eliminate allergies with the help of such drugs, but the manifestations of the disorder decrease.

Unlike older antihistamines, cetirizine acts selectively and alters brain function to a much lesser extent. Therefore, it does not cause such drowsiness as, for example, diphenhydramine or chloropyramine (“Suprastin”).

How should I take Zyrtec?

It is available in the form of tablets and drops. The drug is prescribed by a doctor who monitors the child for allergies.

Take the drug before meals. “Zyrtec” tablets are given only to children over six years old – one tablet once a day.

For younger children, the drug is prescribed in the form of drops. From six months to a year – 5 drops once a day, up to six years – 5 drops twice a day, and older children, like adults, 20 drops once a day.

In this case, if the baby is not yet a year old, it is necessary to use drops: one drop in each nostril after cleansing the nose. Children from one to six years old “Zyrtek” should be dissolved in water.

Side effects and contraindications for taking the drug

The most common side effects of Zyrtek are dry mouth, anxiety, decreased ability to concentrate, feeling tired, sometimes depression. Headaches (including migraines) and diarrhea are much less common.

Absolute contraindication to taking the drug – age up to 6 months. For patients with impaired renal function, the dose of “Zirtek” is selected very carefully.

It is undesirable to use “Zyrtec” simultaneously with theophylline – this combination often causes renal dysfunction. In addition, like any other substance, cetirizine can cause allergies (rashes or swelling). If you take the drug in the doses recommended by the instructions, it will not cause drowsiness and lethargy.

Overdose

If a child has taken more than 50 mg of Zirtek, it is an overdose.Don’t wait until symptoms appear: drowsiness, increased heart rate (tachycardia), dry mouth, constipation, and urinary retention.

Evaluate which will be faster – wait for an ambulance or get to the hospital yourself. Your task is to take the child as soon as possible to where he will receive help and a doctor will monitor his condition.

First aid kit on vacation with children

For kids

Author: Marina Vinogradova

Pediatrician. Doctor of the highest category

Dear mothers, the long-awaited moment has come when you are going on vacation with your baby.Things have been collected, but, as always, at the last moment we remember the first-aid kit. Moreover, it is necessary to take care not only of the baby, but also of the parents. Departure in the morning, most pharmacies are already closed, and you need to take a lot on the road. Many hope for insurance, but we are going to have a rest, and in order not to spoil the rest, let’s take everything we need with us, prepare everything in advance, without fuss, for all emergency situations.

Antipyretic : Nurofen, Paracetamol (Efferalgan, Cefecon).These drugs have both analgesic and anti-inflammatory effects. Allowed from 3 months. Moreover, an increase in temperature on vacation can be both a consequence of heat or sunstroke, and against the background of a viral (bacterial) infection. As a rule, all modern dosage forms have special dispensers designed for the weight of the child. They can be in a wide variety of dosage forms: syrups, suppositories, tablets, capsules. Combined forms (ibuklin) are very convenient. If you are at a loss, paracetamol is prescribed at a dose of 10-15 mg / kg.after 4-6 hours, and nurofen – 5-10 mg / kg. after 6-8 hours. Therefore, combined forms are more convenient. Paracetamol works faster and nurofen takes longer. We take only one drug!
Don’t forget to take the thermometer !
Antiallergic drugs . It must be remembered that they are also available in various forms: syrups, tablets, gels, drops, ointments … the active ingredient is 1-cetirizine, the names of the drugs are different: cetrin, zodak, zirtek. They are given once a day, they are of prolonged action.
Loratadin (claritin), desloratadin (erius) others, zirtek, zodak – from 6 months. But fenistil is allowed from the first month. We take one drug.
I would recommend moms to take Suprastin too. This is a first generation drug, it works quickly in emergency situations, although it has a sedative effect. As a doctor, I always take an ampoule of dexamethasone and a syringe with me, in case of urticaria, Quincke’s edema, we immediately inject i / m, and do not be afraid to make a mistake with the dose, becausethe range goes from 2 to 3, and in severe cases up to 8 mg / kg of weight. We need to provide only emergency assistance, the rest will be prescribed by the doctor.
If there is a situation with external manifestations of allergies, a rash, we use bepanten, fenistil gel, and for the older ones – advantan, triderm, pimafukort, elidel, la-cree . We take one thing, preference for what the child used at home.
Be sure to take the baby daily moisturizing cosmetics , from the lipikar series, mustella, from the la roche pose series.We also take only one drug. We are going to rest, not to be treated.
Do you have a stomach ache, nausea, vomiting, diarrhea? It is imperative that we collect sorbents and preparations for oral rehydration in the first-aid kit (we take only one preparation). Do not burden yourself, you can always buy in addition. From sorbents, we give preference to enterosgel, smecta, polysorb. For rehydration, rehydron, humana electrolyte, biogenic ORS are suitable, we solder slowly, gradually, dosed, 1 tsp every 5 minutes. We follow a dairy-free diet.Drink abundant, at the rate of 20-30 ml. per kg of weight. If the child does not retain water, vomiting continues, we call an ambulance, infusion therapy is needed, there is a risk of dehydration. This is a medical emergency.
Stopped vomiting, but loose unstable stool remains – take enetrofuril, enterol . I would also advise you to take enzymes (creon or microzyme), probiotics (normobact, bakset, florc. Linex …) They are in the form of drops, sachets, capsules. When packaging probiotics, check the storage conditions on the packaging. Many drugs require temperatures up to 15 degrees Celsius.
This can be put in the trunk. But with you on the plane or in the car you need to take dramina (air-sea) . Dramina can be used from the age of 3. At the same time, breast milk can be given to an infant during takeoff and landing, the eldest can be sucked in lozenges, in case of ear pains, Otipax can be dripped into the nose, and vasoconstrictor drops can be applied to the nose. Just distract the child, talk calmly, confidently.
So we come to the topic of drops.Be sure to put in the first-aid kit vasoconstrictor drops in the nose (nasivin, otrivin, tizin …), drops in the ears (otipax, anauran …), eye drops (sodium sulfacyl, vizin, tobradex …). There was a situation when a child developed a clinic of contact conjunctivitis from a long stay in the pool, the sea in 1 day. Family abroad, day off, the nearest pharmacy is a long way to go, the doctor will be there only in the evening. I had to work as a pediatrician.
And now the most important thing – antiseptics .Miramistin. Chlorhexidine. Can be used externally and on mucous membranes. I really love hydrogen peroxide, but, according to some sources, storage conditions are limited – in a dark place, at temperatures up to 15 degrees Celsius. Although the retail network drew attention to the fact that it is allowed to store at room temperature.
Of course, in the first aid kit alcohol wipes, cotton pads, bandage . Earlier, in my student years, iodine and brilliant green, fukarcin were popular. And later they began to be produced in the form of pencils.I’m not very comfortable. Didn’t catch on. But non-alcohol-containing betadine, methylene blue work with a bang. It is convenient to put several tablets of furacillin, and take up little space, dissolved in water – a ready-made antiseptic.
What if the child has a closed injury? First aid – cold to the impact site . The main thing is not to get confused. There is a way out of any situation. If you are on the street, run into the stall, in any freezer there is ice, a cold bottle of drink. And then – traumel, arnica, heparin ointment.If there is an open injury, stop the bleeding. If capillary bleeding is sufficient finger pressure, treat with an antiseptic. In other cases, an emergency call. Do not take responsibility for yourself, do not rely on chance. If the open wound is deep, it is better to sew it up in the first 2 hours, otherwise then tissue edema develops and the risk of secondary infection.
Dear mothers, on vacation, in no case should you shift responsibility for your child to animators, instructors.Dosed exposure to the sun, in the water, diet, sleep regimen are observed by parents. We are going not only to rest, but also to heal the children, so they must return strong and healthy. And now the most important thing is the care products. Sunscreens of a high degree of protection (40 and higher) are mandatory, we give preference to hypoallergenic ones. It is better to check them at home, we take only reliable means. It is unacceptable to be in the sun without a headdress, and it is better to take panamas that cover the ears and neck.And the child should be in a light, loose shirt.
Means for burns based on panthenol, dexapanthenol. Of course, for me, as a doctor, it is not comme il faut to turn to folk medicine, but for sunburns, externally ordinary fermented milk products help outwardly – fat-free yogurt, kefir, whey. All oils and sour cream are excluded. A lipid film is created under them and the risk of secondary infection. Drinking plenty of fluids and hydration are needed.
If you have chronic diseases, take medications that you regularly take with you + additionally with a 1 week reserve.Situations are different. And health is more expensive. And put some of it not in your luggage, but in your travel bag. Suddenly the luggage will go to another hotel by mistake. Of course, if the child often obstructs, you need to take an inhaler with you – a nebulizer, nebulas with pulmicort (budesonide), berodual or ventolin, salbutamol.
I am not suggesting that parents take antibiotics. Cough medicines. We are going to rest. This is the installation. The rest can be purchased as planned. And you shouldn’t run a pharmacy that needs to be updated periodically, throw away expired drugs.
If you are going to the forest, maybe you should get vaccination against tick-borne encephalitis , take broad-spectrum antibiotic , based on amoxicillin with clavulanic acid, if an unpleasant encounter with a tick occurs. In doing so, observe all safety precautions.
If you are traveling to the mountains, you also need visin-based eye drops sunscreen products.

Happy holidays, positive emotions!

Zodak: spring without allergies or hibernation?

A review on urticaria states that many antihistamines are effective in treating the problem completely and none of the drugs (including cetirizine or levocetirizine) are superior in effectiveness.Cetirizine and levocetirizine at normal doses do not work immediately, but cure can be accelerated by taking 20 mg of levocetirizine. However, this conclusion is based on few studies or even descriptions of individual clinical cases. No withdrawal syndrome was observed with the drugs compared with the placebo group.

Chronic cough in children, according to a 2008 review, is unlikely to resolve with cetirizine (if it does, it will take about two weeks), and the risk of side effects outweighs the expected benefit.

Finally, two reviews look at the efficacy of antihistamines for eczema, and the results are summarized in a question and answer format. Despite the fact that antihistamines are often prescribed for eczema, their effectiveness and safety (both individually and in combination with topical agents – ointments, creams, lotions) have not been proven.

Indicator.Ru recommends: the drug will help, but not everyone

Like many antihistamines for allergies, Zodak (aka Zyrtec), as well as drugs with levocetirizine, relieve the symptoms of rhinitis, hay fever, urticaria and other unpleasant misfortunes. both seasonal and chronic.They will not save you from some diseases (for example, eczema). For a chronic (presumably allergic) cough in children, cetirizine is most likely not useful, as with antiretroviral drug allergies. For urticaria, drugs will help in large doses for short-term use, and with medium periods of use – in the usual dosage (10 mg per day for Zodak, 5 mg for levocetirizine).

However, firstly, they will not cure you forever, and secondly, almost half of the patients will not feel any relief (for levocetirizine drugs, this figure is slightly less).The first problem is common to all antihistamines, the second is also common. In addition, many studies are funded by manufacturers who are interested in promoting and selling. Do they publish negative data? Are the incidence of side effects being underestimated? It is impossible to answer these questions with certainty.

But it is not so scary if the drug does not treat allergies (treating allergies is difficult, long and generally not always possible), since it relieves symptoms and does not complicate life.Taking antihistamines (for example Suprastin), patients often complain of drowsiness, fatigue, weakness and nausea, because such drugs lower blood pressure and can distort the sleep and wake cycles. But in comparison with the first generation antihistamines, the representatives of the second (to which Zodak belongs) have fewer side effects. In addition, Zodak does not penetrate the blood-brain barrier in large quantities, so its effect on the nervous system will not be significant.

Another disadvantage of antihistamines is a possible withdrawal syndrome.When the body gets used to the fact that the work of histamine is constantly suppressed, it may not immediately react if such an effect has abruptly disappeared. Therefore, if you take the drug for a long time, you need to slowly reduce the dosage at the end, so as not to be left with a (stuffy) nose and in tears after the end of the course.

Ask an allergist a question – Questions and answers

Hello Julia!

It is always difficult to answer unfamiliar, non-native patients, because there is no common language, so I will try not to disappoint you:

1) Lactase deficiency – a condition not related to food allergies, is well compensated by a decrease in the proportion of milk sugar (lactose) in the daily diet of a person. Accordingly, unpleasant symptoms (gas, colic, “like constipation” despite the fact that the stool is liquid, frothy, green, with a sharp sour odor) disappear in babies when milk is replaced with complementary foods or when the enzyme lactase is added to each portion of milk.Many adults also have problems with lactose and lactase deficiency, finding an intuitive way out – “dislike” for unleavened milk, cream, ice cream, etc. , while they can usually afford dairy products.

2) If by the age of 3 years the baby has not only symptoms from the gastrointestinal tract (see item 1), but also some manifestations of “allergy to milk and beef-veal-venison”, then probably we are talking about dermatitis or allergic rhinitis or asthma or anaphylaxis (they can be combined or replace each other) and an allergy to milk proteins (not sugar).Here, the reaction mechanism is immune, sometimes it is associated with specific IgE (and this option is the most unpleasant, dangerous, not inclined to pass with age), sometimes it is not (due to non-IgE mechanisms, for example, cellular mechanisms of allergy). Conclusion: you need an allergy examination and discussion of the results with a doctor who knows and leads your child. The cherished “certificate that the kindergarten requires” can be the result of such a visit to the doctor.

3) The most informative and accurate answer to the question of whether the IgE mechanism of allergy really lies behind the symptoms is answered by ImmunoCAP or Immulite to cow’s and goat’s milk, casein, beef and soy – f 2.f300. f78. f 27. f14 (this is the survey code). I hope that such testing is available in your city.

4) Treatment of dermatitis. rhinitis. asthma is not limited to a single recommendation to “eliminate the culprit and the cross-products.” Therefore, it makes sense to find a doctor who will tell, advise, teach and inspire you to do more for the health of your son or daughter. Let the little person have a big support group!

Zyrtec (Cetirizine): detailed instructions for use

Expert opinion of the medical board of Polismed

We have collected frequently asked questions and prepared answers to them

Which form of release is more effective?

A friend advised me to drink Zyrtec for allergies, but I would like to know which is more effective – pills or drops?

Reply of the Medical Board

I would like to note right away that it is best to treat any allergic disease not “by acquaintance”, but by a specialist.Ideally, it would be worth visiting an allergist, but a regular therapist can also prescribe the necessary medication. The advantage of an official visit to a doctor is that, in addition to an examination that will allow you to establish the cause of the allergy, when prescribing the drug, he will tell you how to take it, how long to treat it, and which form of release – drops or tablets of Zirtek – will suit you more.

What is the right way to give to a child?

The grandson fell ill with chickenpox, Zyrtek was appointed as a doctor for itching, and friends fought the itch with Fenistil, I would like to clarify which is better for the child – Fenistil or Zyrtek, or maybe Suprastin is suitable? How many drops of Zirtek can be given to children with chickenpox, and at what age?

Reply of the Medical Board

If we talk about the benefits of the drugs you mentioned, and about which drug to choose for children, including those up to one year old, then Zyrtec is the undoubted leader in this regard.This is a third generation drug that has a minimal number of side effects, mainly, it has practically no sedation. Therefore, it should be changed to fenistil, and even more so to Suprastin, only if he does not help the child at all.

For children, the dosage of Cetrin is determined by their age: children from 6 months to a year are prescribed 5 drops once a day, from a year to 2 – you can take 5 drops twice a day, from 2 to 6 years, it is better to 10 drops per a day once or divided into two doses.Zyrtec is not recommended for a newborn, since its safety has not been studied.

Can be used during pregnancy / lactation?

During my first pregnancy, especially in the 3rd trimester, I suffered from itchy skin. Now I am pregnant for the second time, 1 trimester, I am very afraid that itching will appear again. Can I take Zyrtec to eliminate it?

Reply of the Medical Board

In the official instructions to Zyrtek, it is said that the drug is not recommended for use during pregnancy and breastfeeding.We know that some pregnant women used Zyrtec, but we cannot recommend it for use. You should consult an allergist doctor to find out the cause of this skin itching, most likely it is associated with a change in eating habits during pregnancy.

How to take it right?

I have seasonal allergies and have to take antihistamines regularly in the spring. How many days should I take Zyrtec after the allergic plants have faded? How long does the plate with pills last after opening – can I finish it next year?

Reply of the Medical Board

The therapeutic effect of the course intake of Zirtek persists after the cancellation of at least 3 days.However, the fact that the plants that cause allergies have stopped blooming does not at all guarantee that there are no allergens left in the air. Therefore, you can take Zyrtec for another 1-2 weeks.

In terms of expiration dates, the pill blister can be stored until the expiration date, which is 5 years, so it is possible that you can “finish off” the rest of the drug for the next year.

Which is better – Zyrtec or analogues?

The allergist prescribed Zyrtek, and when we came to the pharmacy, it turned out that there was no medicine.The pharmacist began to offer analogues of this drug – Erius and Zodak. However, we do not know which of all this is better: Zodak, Cetrin or Erius. In addition, they are all quite expensive, maybe it is better to buy Claritin instead of Zirtek?

Reply of the Medical Board

In all the drugs you listed, except for Claritin, the active ingredient is cetirizine, so there is no fundamental difference in their action. Claritin belongs to the second generation antihistamines, although in terms of effectiveness it is not much inferior to the other drugs you mentioned.

Which one is better of all these drugs (Tsetrin, Zodak, or Erius) cannot be said for sure: one drug helps someone better, another helps someone better. A general recommendation when buying these products: try to take original products, not generics of Indian or Chinese origin.

Description of the drug
Antihistamines are used to relieve or prevent symptoms hay fever and other types of allergies.They work by preventing the action of a chemical called histamine, which is synthesized by the body. Histamine can cause itching, sneezing, runny nose, and watery eyes. In some people, histamine causes bronchial constriction and breathing difficulties.
Certain antihistamines are also used to prevent motion sickness, nausea, vomiting, and dizziness. In the case of Parkinson’s disease , Diphenhydramine can be used to reduce stiffness and tremors. Diphenhydramine syrup is also used to relieve coughs caused by the common cold or hay fever . In addition, since some antihistamines can cause drowsiness as a side effect, some of them can be used as sleeping pills.
Hydroxyzine is used in the treatment of neurological and mental illness as it helps control anxiety. It can also be used to control anxiety and sleepiness before surgery.
Certain antihistamines are used to treat chronic urticaria, which looks like a persistent rash of blisters.
Antihistamines may also be used to treat other conditions, if recommended by a physician.
Antihistamines are available both prescription and over-the-counter.
Do not give OTC cold medicines to children under 4 years of age. Using these drugs at this age can lead to serious and even life-threatening side effects.
Once a drug is approved for a specific medical purpose, experience may show that it is also useful for other health problems. Although such cases are not included in the instructions for the medication, some antihistamines are used, for certain patients, in the following situations:
Stimulating appetite in children and adults ( cyproheptadine )
In asthma , together with other anti-asthma drugs, before or during contact with substances that cause a reaction, in order to prevent or reduce bronchospasm – shortness of breath or shortness of breath ( cetirizine and loratadine )
Treatment of vascular headache ( cyproheptadine )

What you need to know before use?
When deciding whether to take a drug, the risks and benefits of the drug must be weighed.This decision is made not only by you, but also by the doctor. Consider the following factors for this drug:

Allergic reactions
Tell your doctor if you have had any form of allergic reaction to this drug or any other drugs. Also, be sure to report any other allergies, including to foods, dyes, preservatives, or animals. Before taking over-the-counter drugs, read the instructions and the ingredients list carefully.

Prescribing the drug to children
The younger the patient, the higher the risk of serious complications such as seizures, the highest risk is in children under one year old.In general, the effect of antihistamines in children is stronger. Children are also more likely to have nightmares, unusual agitation, nervousness, fatigue, or irritability.
Do not give any over-the-counter cough or cold medicine to children under 4 years of age. In young children, these drugs can cause severe and even life-threatening side effects.

Prescribing the drug to the elderly
Elderly people are more sensitive to the effect of antihistamines.More often, they experience partial clouding of consciousness, difficulty or pain when urinating, dizziness, drowsiness, light-headedness, dryness of the mucous membranes of the mouth, nose and throat. The elderly are also more likely to have nightmares, unusual agitation, nervousness, fatigue, or irritability.
Pregnancy
During the first months of pregnancy, it is not recommended to take hydroxyzine , since it has been shown in animal experiments that in doses many times higher than the usual dose, it causes malformations.Be sure to discuss this point with your doctor.
The effect of desloratadine and fexofenadine on pregnant women has not been studied. But animal studies have demonstrated that these drugs cause malformations or other problems at doses higher than the usual dose for humans. Before taking these drugs, be sure to tell your doctor that you are pregnant or may become pregnant in the near future.
The effect of azatadine, brompheniramine, cetirizine , chlorpheniramine, clemastine , cyproheptadine , dexchlorpheniramine, dimensionhydrinate , diphenhydramine , doxiline were studied.In animal studies, these drugs have not caused birth defects or other problems associated with pregnancy.

Breastfeeding
Small amounts of antihistamines pass into breast milk. Because infants are more likely to develop side effects (such as unusual agitation or irritability), taking antihistamines while breastfeeding is not recommended. In addition, because antihistamines reduce the secretion of various glands, it is believed that they decrease the production of breast milk in some patients.It is not yet known whether cetirizine , desloratadine , or loratadine have such an effect.

Interaction with other medicinal products
Antihistamines should not be taken simultaneously with some medications, in some other cases, simultaneous administration is possible, even if they may interact. In such cases, the doctor may change the dose or take other precautions. If you are taking antihistamines, be sure to tell your doctor if you are taking any of the following drugs.The most important points are listed below, this list is not exhaustive.

Taking antihistamines with these drugs is not recommended. The doctor may refuse the appointment of a drug or to choose another, more suitable:

Missed medication
If you miss a medication, take it as quickly as possible.If it’s almost time for a new appointment, skip the late appointment and return to your regular appointment schedule. Don’t double your dose.

Storage
Store the medication in a closed container at room temperature, in a place protected from overheating, moisture and direct sunlight. Do not freeze the medicine.
Keep out of reach of children.
Do not store an expired or no longer required medicine.

Precautions
Before having an allergy test, tell your doctor that you are taking these drugs, as they may affect test results.
If you take antihistamines regularly, tell your doctor if you are taking aspirin as much (for example, to treat arthritis or rheumatism). Signs of aspirin overdose (such as ringing in the ears) may not show up due to antihistamines.
Antihistamines may increase the effects of alcohol and other substances that depress the brain and cause drowsiness. These include sedatives, tranquilizers, sleeping pills, prescription pain relievers and drugs, barbiturates, anticonvulsants, muscle relaxants and anesthetics, including dental ones.Talk to your doctor before taking any of these medications.
Antihistamines cause drowsiness and slow reactions in some people. Even if you take them before bed, you may feel sleepy or slow to react upon waking. Some antihistamines cause more sleepiness than others. Drowsiness is less common with cetirizine, rarely desloratadine and loratadine. Before you get behind the wheel of a car, use various devices and mechanisms, or do anything else that requires attention, determine if your drug is causing drowsiness in you personally.
Antihistamines may cause dry mouth, nose, and throat. Some drugs cause dryness more often than others. For temporary relief from dryness, use sugarless candy or chewing gum, ice cubes, or artificial saliva. If dryness persists for more than 2 weeks, check with your doctor or dentist. Prolonged dryness can cause dental disease, including tooth decay, gum disease, and fungal infections.
Dimenhydrinate, diphenhydramine and hydroxyzine reduce nausea and vomiting, so they can mask symptoms of other drug overdose or appendicitis, making it difficult to diagnose these conditions.If you have other symptoms of appendicitis, such as pain in the stomach or lower abdomen, cramping, or tenderness, be sure to tell your doctor that you are taking these drugs. If you think you might be overdose, tell your doctor which antihistamines you are taking.
If you are already taking sedatives or tranquilizers, do not start taking diphenhydramine or doxylamine to improve sleep without consulting your doctor.
