Zyrtec Oral: Uses, Side Effects, Interactions, Pictures, Warnings & Dosing


Cetirizine is an antihistamine used to relieve allergy symptoms such as watery eyes, runny nose, itching eyes/nose, sneezing, hives, and itching. It works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction.Cetirizine does not prevent hives or prevent/treat a serious allergic reaction (such as anaphylaxis). If your doctor has prescribed epinephrine to treat allergic reactions, always carry your epinephrine injector with you. Do not use cetirizine in place of your epinephrine.

How to use Zyrtec

If you are taking the over-the-counter product to self-treat, read all directions on the product package before taking this medication. If you have any questions, consult your pharmacist. If your doctor has prescribed this medication, take it as directed, usually once daily.

If you are using the chewable tablets, chew each tablet well and swallow. If you are using the rapidly-dissolving tablet, allow the tablet to dissolve on the tongue and then swallow, with or without water. If you are using the liquid form of this medication, measure the dose carefully using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

The dosage is based on your age, medical condition, and response to treatment. Do not increase your dose or take this medication more often than directed.

Tell your doctor if your allergy symptoms do not improve, if your hives do not improve after 3 days of treatment, or if your hives last more than 6 weeks. Get medical help right away if your condition worsens or if you think you have a serious medical problem (such as a very serious allergic reaction/anaphylaxis).

Side Effects

Drowsiness, tiredness, and dry mouth may occur. Stomach pain may also occur, especially in children. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

If your doctor has prescribed this medication, remember that your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: difficulty urinating, weakness.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

9 Zyrtec Side Effects To Know Before Taking Allergy Medicine

If you're stocking up on OTC allergy medicine right now, you're not alone. The changing of seasons tends to bring on not-so-fun allergy symptoms, and daily meds can help so enjoying time outside is NBD, like the popular one Zyrtec.

Zyrtec claims to be the "#1 Allergist Recommended Brand Among OTC Oral Antihistamines" so it probably seems like a safe bet in the pharmacy aisle, and you'd be right about that. “Zyrtec blocks histamines to stop allergic reactions,” says Virginia Boomershine, ambulatory clinical pharmacy regional senior manager for Banner Pharmacy Services. Histamines are substances that cause all those send-you-to-misery-town allergy symptoms.

Zyrtec, in particular, treats those like runny nose, sneezing, itchy, watery eyes, and itching of the nose or throat. You're supposed to take one tablet per day and it starts working within one hour of consumption. (Yaaaaasss.)

And because it can magically make you feel better, you may be tempted to keep a regular stash of Zyrtec on hand. So, here's what you should know about Zyrtec, potential side effects (more on those in a minute!), who it's right for, and more.

Is it safe to take Zyrtec every day?

Yep. "When taken in the recommended doses, antihistamines can be taken daily. This is especially true with Zyrtec, since it doesn't show decreasing effectiveness if used daily," says Sima Patel, MD, an allergist at New York Allergy & Sinus Centers.

Zyrtec and other allergy medicines currently on the market are known as second-generation antihistamines, and have fewer and less severe side effects than the "first generation" of allergy medications did. So though you might experience some side effects while on allergy medicine, they shouldn't persist once you've stopped taking it.

Still, it's probably worth holding off on medication that you don't need, says Dr. Patel. So if you aren't having allergy symptoms or they get milder during a certain time of the year, that's probably a good time to take a Zyrtec break. "We always want the least amount of medication to control symptoms. However, starting allergy medications two weeks prior to your symptomatic season is best to help prevent symptoms," Dr. Patel says.

Mild side effects may be totally normal, but if you're experiencing severe side effects, or persistent ones that just won't go away, it's best to talk to your doctor before you continue regular use of Zyrtec to see if its right for you.

Is it better to take Zyrtec in the morning or at night?

It depends on whether you experience any side effects, says Robert Eitches, MD, an allergist at Tower Allergy. If your problems are only during the day time and you aren't really prone to side effects, then go ahead and take it during the day.

But if you experience side effects like drowsiness, Dr. Eitches recommends taking your dose at night before bed. "That way you wake up in the morning relatively clearer, too," he says. If it makes you sleepy, the side effect will have likely worn off by the time you wake up, and since the medication can provide relief for 24 hours, you'll still experience relief during the day.

Is there anyone who should not take Zyrtec?

Zyrtec is safe for most people, but there are some populations that should stay away from it. Children under 2, anyone with a history of allergic reaction to Zyrtec or hydroxyzine/piperazine derivatives, and people with severe renal impairment are all people who probably shouldn't take Zyrtec, says Dr. Patel. For people with these conditions, Zyrtec can cause adverse health effects.

If you are pregnant and breastfeeding, Dr. Patel recommends speaking to your doctor before using it, since some women have experienced side effects. Dr. Eitches suggests taking it with caution if you're on other medications or take some kind of sleeping aid to help you go to bed.

When in doubt, it's best to go to your doctor with any questions before you take Zyrtec as an allergy medicine.

All things considered though, you’re likely to be fine when using Zyrtec, as side effects aren’t terribly common, Boomershine notes. Still, it's best to be aware of potential Zyrtec side effects—especially if you're planning on popping the stuff on the reg over the next few months.

9 Zyrtec Side Effects To Be Aware Of



If you've ever slept 14 hours after popping a Benadryl, you're well aware that some allergy meds can seriously knock you out. That's not as common with Zyrtec, but 11 to 14 percent of people do report feeling sleepy after taking it, making it the most common side effect reported, says Boomershine.

Since the effects of Zyrtec last 24 hours, drowsiness can hit at any time. Avoid alcohol and be careful about driving if the med hits you with the sleepies, per the Zyrtec site.


Dry Mouth

It’s annoying to feel as if you’ve inhaled a mouthful of sand. Less than 10 percent of Zyrtec poppers will wind up with a dry mouth, says Boomershine. When you have an allergic response, your tissues secrete more fluid (hello runny nose, watery eyes), and antihistamines dry you up. She says that drinking water will help, as will switching to an alcohol-free mouthwash if you’re using one that has alcohol in it, as that ingredient also dries you out.



Dizziness can be a rare potential side effect and may disappear after your body adjusts to the medication, per The Mayo Clinic. Give it time, but always check in with your doctor if you’re concerned. And, just like drowsiness, hold off on driving if you’re getting dizzy spells.



This is one of those side effects that may or may not be attributable to Zyrtec, especially since the causes of head pain are so multifactorial. If possible, take a break from the med and see if it helps, says Boomershine. If so, you can always chat with a pharmacist to see if there’s a different allergy med that may be better for you.



Truth: Just about every med you take can come with the side effect of nausea. It will likely always be listed. “When doing clinical trials, the drug manufacturer has to write down every side effect everyone says happened to them. In terms of Zyrtec, experiencing nausea on the medication happens as commonly as taking a placebo,” she says. So it may be the Zyrtec, it may not be. Taking it with food is always a good way to avoid potential nausea.



While Zyrtec may make adults sleepy, it can turn kids into little insomniacs, says Boomershine. Having them take the long-acting med earlier in the day won’t help either since it lasts all day. Talk to their pediatrician about making a switch.


Difficulty breathing or swallowing

It’s rare, according to the National Institutes of Health, but keep it on your radar anyway. While you may be taking Zyrtec to prevent allergy symptoms, it’s possible to have a potentially deadly allergic reaction called anaphylaxis from the medication itself. (FYI: This is a risk will all medications, not just Zyrtec.) If you experience this, call 911 immediately.


Sore throat/cough

If you experience a sore throat while taking Zyrtec, it's likely because your mucus membranes become drier causing the tissues in your mouth to also feel a little drier and lead to a sore throat, says Dr. Eitches. Coughing can be an instinct response to try to moisten the mouth, he explains.

To combat this, stay hydrated. But if this side effect becomes too severe, Dr. Eitches suggests switching to a different antihistamine.



Constipation is a very rare side effect that happens due to a drug's anticholinergic effect, which means the drug blocks neurotransmitters which affect how the body functions. In this case, certain receptors that help gut motility are blocked. This side effect was much more common with older, first generation antihistamines such as Benadryl, says Dr. Patel, but Zyrtec is a second-generation antihistamine with less side effects.

If this does happen to you though, Dr. Eitches recommends trying a different antihistamine, adding fiber to your diet, and staying well-hydrated.

Cetirizine dihydrochloride 10 mg.

Excipients: methyl parahydroxybenzoate, propyl parahydroxybenzoate, glycerol, propylene glycol, sodium saccharinate dihydrate, sodium acetate trihydrate, glacial acetic acid, purified water.

Pharmacological effect

Cetirizine is a hydroxyzine metabolite, belongs to the group of competitive histamine antagonists, blocks histamine H1 receptors.

In addition to the antihistamine effect, cetirizine prevents the development and alleviates the course of allergic reactions: at a dose of 10 mg 1 or 2 times / day, it inhibits the late phase of eosinophil aggregation in the skin and conjunctiva of atopic patients. After oral administration, the antiallergic effect of cetirizine lasts for 24 hours.

Clinical efficacy and safety

Studies in healthy volunteers have shown that cetirizine at doses of 5 or 10 mg significantly inhibits the rash and redness response to high concentrations of histamine in the skin, but no correlation with efficacy has been established.

In a 6-week, placebo-controlled study of 186 patients with allergic rhinitis and concomitant mild to moderate asthma, cetirizine 10 mg once daily was shown to reduce symptoms of rhinitis and not affect lung function. nine0003

The results of this study confirm the safety of the use of cetirizine in patients with allergies and mild to moderate bronchial asthma.

In a placebo-controlled study, cetirizine 60 mg daily for 7 days did not cause clinically significant QT interval prolongation.

The use of cetirizine at the recommended dose has been shown to improve the quality of life of patients with year-round and seasonal allergic rhinitis. nine0003


In a 35-day study in patients aged 5-12 years, there was no evidence of resistance to the antihistamine effect of cetirizine. The normal skin reaction to histamine was restored within 3 days after discontinuation of the drug with repeated use.

A 7-day, placebo-controlled study of cetirizine syrup in 42 patients aged 6 to 11 months demonstrated safety of the drug. Cetirizine was administered at a dose of 0.25 mg/kg 2 times a day, which corresponded approximately to 4.5 mg per day (dose range was from 3.4 to 6.2 mg per day). nine0003

Use in children aged 6 to 12 months is possible only on prescription and under strict medical supervision.


Pharmacokinetic parameters of cetirizine when used in doses of 5 to 60 mg change linearly.


Cmax in blood plasma is achieved after 1±0.5 h and is 300 ng/ml. Various pharmacokinetic parameters such as Cmax and AUC are homogeneous. Eating does not affect the complete absorption of cetirizine, although its rate decreases. nine0003

The bioavailability of various dosage forms of cetirizine (solution, capsules, tablets) is comparable.


Plasma protein binding is approximately 93±0.3%. Vd is 0.5 l/kg. Cetirizine does not affect the binding of warfarin to proteins.

When administered orally at a daily dose of 10 mg for 10 days, no accumulation of cetirizine was observed.


Cetirizine does not undergo extensive primary metabolism. nine0003


T1 / 2 is approximately 10 hours. Approximately 2/3 of the dose taken is excreted in the urine unchanged.

Pharmacokinetics in special clinical situations

Elderly patients. In 16 elderly patients, with a single dose of the drug at a dose of 10 mg, T1 / 2 was 50% higher, and the clearance was 40% lower compared to younger patients. Decreased clearance of cetirizine in elderly patients is likely due to a decrease in renal function in this category of patients. nine0003

Patients with renal insufficiency. In patients with mild renal insufficiency (CC> 40 ml / min), pharmacokinetic parameters are similar to those in healthy volunteers with normal renal function. In patients with moderate renal insufficiency and in patients on hemodialysis (QC

Patients with hepatic insufficiency. In patients with chronic liver diseases (hepatocellular, cholestatic and biliary cirrhosis), with a single dose of the drug at a dose of 10 or 20 mg, T1 / 2 increases by about 50%, and clearance decreases by 40% compared with healthy volunteers. Dose adjustment is necessary only if a patient with hepatic impairment also has concomitant renal impairment. nine0003

Children. In children aged 6 to 12 years, T1 / 2 is 6 hours, at the age of 2 to 6 years - 5 hours, at the age of 6 months to 2 years it is reduced to 3.1 hours. symptoms of year-round (persistent) and seasonal (intermittent) allergic rhinitis and allergic conjunctivitis (itching, sneezing, nasal congestion, rhinorrhea, lacrimation, conjunctival hyperemia).

Symptoms of chronic idiopathic urticaria.


Hypersensitivity to cetirizine, hydroxyzine or piperazine derivatives, as well as to other components of the drug.

End stage renal disease (CC

Children under 6 months of age (due to limited efficacy and safety data).



Chronic renal insufficiency (CC>10 ml / min, dosing regimen adjustment required). nine0003

Epilepsy and increased convulsive readiness.

Patients with predisposing factors for urinary retention (spinal cord injury, prostatic hyperplasia).

Elderly patients (with age-related decrease in GFR).

Children under 1 year of age.

Breastfeeding period.

Use in pregnancy and lactation


Prospective data analysis of more than 700 pregnancy outcomes revealed no cases of malformations, fetal and neonatal toxicity with a clear causal relationship. nine0003

Animal studies have not revealed any direct or indirect adverse effects of cetirizine on the developing fetus (including in the postnatal period), pregnancy and postnatal development. Adequate and strictly controlled clinical studies on the safety of the drug during pregnancy have not been conducted, so Zodak should not be used during pregnancy.


Cetirizine is excreted in breast milk in an amount of 25% to 90% concentration of the drug in plasma, depending on the time after administration. During breastfeeding, use after consulting a doctor if the intended benefit to the mother outweighs the potential risk to the child.


Available data on the effects on human fertility are limited, but no adverse effects on fertility have been identified.

Dosage and administration

Inside, drip into a spoon or dissolve in water. The amount of water to dissolve the drug should correspond to the amount of liquid that the patient (especially the child) is able to swallow. The solution should be taken immediately after preparation. nine0003

Adults 10 mg (20 drops) once daily.

Elderly patients. There is no need to reduce the dose in elderly patients if renal function is not impaired.

Patients with renal insufficiency. Since cetirizine is excreted from the body mainly by the kidneys, if alternative treatment is not possible in patients with renal insufficiency, the dosage regimen of the drug should be adjusted depending on renal function (CC value).

Side effects

From the side of the hematopoietic system: very rarely - thrombocytopenia.

From the immune system: rarely - hypersensitivity reactions, very rarely - anaphylactic shock.

Mental disorders: infrequently - agitation, rarely - aggression, confusion, depression, hallucinations, sleep disturbance, very rarely - tic, frequency unknown - suicidal ideation.

From the nervous system: infrequently - paresthesia, rarely - convulsions, very rarely - taste perversion, dyskinesia, dystonia, fainting, tremor, frequency unknown - memory impairment, incl. amnesia. nine0003

On the part of the organ of vision: very rarely - disturbance of accommodation, blurred vision, nystagmus.

From the side of the organ of hearing: the frequency is unknown - vertigo, deafness.

From the side of the cardiovascular system: rarely - tachycardia, the frequency is unknown - vasculitis.

From the digestive system: infrequently - diarrhea, rarely - changes in liver function tests (increased activity of transaminases, alkaline phosphatase, GGT and bilirubin), the frequency is unknown - increased appetite.

From the skin and subcutaneous tissues: infrequently - skin rash, pruritus, rarely - urticaria, very rarely - angioedema, persistent drug erythema.

From the urinary system: very rarely - dysuria, enuresis, the frequency is unknown - urinary retention.

From the musculoskeletal system: the frequency is unknown - arthralgia.

General disorders: infrequently - asthenia, malaise, rarely - peripheral edema, weight gain.

Description of selected adverse reactions

Cases of pruritus (including intense pruritus) and/or urticaria have been reported following discontinuation of cetirizine.


The clinical picture observed in overdose of cetirizine was due to its effect on the central nervous system.

Symptoms: after a single dose of cetirizine at a dose of 50 mg, the following clinical picture was observed - confusion, dizziness, drowsiness, lethargy, stupor, weakness, anxiety, irritability, sedation, fatigue, malaise, headache, mydriasis, itching, tachycardia, tremor, urinary retention, dry mouth, diarrhea, constipation. nine0003

Treatment: gastric lavage or induction of vomiting should be carried out immediately after taking the drug. The appointment of activated charcoal, symptomatic and supportive therapy is recommended. The specific antidote is unknown. Hemodialysis is ineffective.

Interaction with other drugs

No clinically significant interaction of cetirizine with other drugs has been established.

Based on the results of drug interaction studies with cetirizine, in particular, interaction studies with pseudoephedrine or theophylline at a dose of 400 mg / day, no clinically significant interaction has been established. nine0003

Simultaneous use of cetirizine with ethanol and drugs that depress the central nervous system may further reduce concentration and reaction time, although cetirizine does not enhance the effect of ethanol (at its blood concentration of 0.5 g / l).

Special instructions

cetirizine may increase the risk of urinary retention. nine0003

Caution is advised when using cetirizine concomitantly with alcohol, although no clinically significant interaction with ethanol has been observed at therapeutic doses (at a blood ethanol concentration of 0.5 g/l).

Caution should be exercised in patients with epilepsy and increased convulsive readiness.

A three-day "wash-out" period is recommended before allergological testing because histamine H1 receptor blockers inhibit the development of allergic skin reactions. nine0003

Pediatric use

Due to potential CNS depressant effects, caution should be exercised when prescribing Zodak to children under 1 year of age with the following risk factors for sudden infant death syndrome, such as (but not limited to):

sibling sleep apnea or sudden infant death syndrome,

maternal drug or smoking abuse during pregnancy,

young age of the mother (19 years and younger),

excessive smoking of the babysitter (1 pack of cigarettes per day or more),

children who regularly fall asleep face down and who are not laid on their backs,

preterm ( less than 37 weeks' gestational age) or underweight (below 10th percentile of gestational age) infants,

when co-administered with CNS depressant drugs.

The preparation contains excipients methylparabenzene and propylparabenzene, which can cause allergic reactions, incl. slow type. nine0003

Influence on the ability to drive vehicles and mechanisms

An objective assessment of the ability to drive vehicles and work with mechanisms did not reliably reveal any adverse events when using Zodak in recommended doses. However, for patients with manifestations of drowsiness while taking the drug during the period of treatment, it is advisable to refrain from driving, engaging in potentially hazardous activities or operating mechanisms that require increased concentration and speed of psychomotor reactions. nine0003

Storage conditions

Store under normal conditions, out of the reach of children.

Allergic rhinitis is a disease accompanied by itching in the nasal cavity, endless watery discharge from the nose, paroxysmal sneezing and absolute nasal congestion. And such symptoms appear with the beginning of flowering plants. It's all about the reaction of the body to irritating factors from the outside. In the case of allergic rhinitis, this is plant pollen.

During this period, people suffering from this disease are helped by antihistamines. One of them is Zyrtec. We asked pharmacist Kristina Khokhrina to tell us more about it, and this is what she told us: what it is used for, what is included in the composition of the product, in what dosage it is used and whether it is suitable for children. We also provided a small list of similar antihistamines and found differences between Zirtek and Zodak, Citrine and Erius. nine0003 All products Zirtek

Zirtek: what

Zirtek is used for for allergies. The main indications for the use of Zirtek:

  • allergic rhinitis
  • allergic conjunctivitis
  • symptoms of chronic urticaria

The drug acts on the skin one hour after ingestion. Maximum efficiency is achieved within 2-12 hours. The effect gradually decreases, but persists for a day.

Zyrtec active ingredient

Zyrtec: Composition

Zyrtec is available in two forms: drops and tablets. Let's talk about the composition of both drugs. The active substance in both forms is the same, only the auxiliary components change, since they determine the form of the drug.

Zyrtec drops: glycerol, propylene glycol, sodium saccharinate, methylparabenzene, propylparabenzene, sodium acetate, glacial acetic acid, purified water.

Zyrtec tablets: microcrystalline cellulose, lactose monohydrate, colloidal silicon dioxide, magnesium stearate, hypromellose, titanium dioxide, macrogol. nine0003

Zyrtec: dosage

The dosage of Zyrtec is determined by the amount of active ingredient per 1 ml drops or 1 tablet. In both cases, cetirizine is contained in a dosage of 10 mg.

The drug is prescribed for adults and children from 6 months. For each age, a certain dose is established. The manufacturer recommends taking Zirtek in the evening, as the symptoms of allergic diseases are most pronounced at night. It is taken with or without food and can be taken with water as needed. nine0003

Adults are advised to take 20 drops or 1 tablet once a day, which corresponds to a dosage of the substance 10 mg. Reception Zirtek in drops can be single in the evening or divided into 2 doses. For example, 10 drops in the morning and evening.

Zyrtec side effects

Zyrtec may rarely cause the following side effects:

  • general fatigue
  • dizziness
  • headache nine0322
  • abdominal pain
  • dry mouth
  • nausea
  • drowsiness

Children may additionally develop diarrhea. When taking medication, pay attention to your condition. If any changes appear, described or not described in the instructions, or if allergy symptoms increase, consult a doctor.

Zyrtec drops for children

Zyrtec should only be used in children from 6 to 12 months of age on prescription and under the supervision of a physician. The drug is prescribed depending on age: nine0003

  • 6 to 12 months: Take 5 drops (2.5 mg) once a day
  • 1 to 6 years: Take 5 drops (2.5 mg) twice a day in the morning and evening, or 10 drops (5 mg) once a day in the evening
  • 6 to 12 years: Take 20 drops (10 mg) once daily
  • over 12 years old: take 20 drops (10 mg) once a day

Zyrtec may be used during pregnancy only after consulting a physician if the expected benefit to the mother outweighs the potential risk to the fetus. The same applies to use during lactation, since cetirizine passes into the mother's breast milk. nine0003

Zyrtec: analogues

Zyrtec is one of the representatives of the group of antihistamines. Its analogues contain the same active ingredient: cetirizine:

  • Cetirizine
  • Zincette
  • Zodak
  • Cetrin
  • Sensor
  • Soloneks

Preparations with a different composition, such as Erius, can also be analogues of Zirtek. Let's compare Zodak with some of the remedies from this list.

Zirtek or Zodak: which is better

The drugs have the same active ingredient, which defines them as antiallergic drugs. Indications for use, dosage of the active substance, side effects and other characteristics of Zirtek and Zodak are the same. nine0003

The preparations are as similar as possible and even have the same forms of release: drops and tablets. The only difference is the manufacturers. Zyrtec is made in Switzerland, and Zodak is made in Russia, which is reflected in the price of the funds. Therefore, when choosing what is better to buy: Zodak or Zirtek, be guided by your preference, since the drugs are identical in terms of effectiveness.

Zyrtec or Cetrin: which is better
