Zyrtec and its drug substance Cetirizine Hydrochloride

Zyrtec is the trade name for Cetirizine Hydrochloride. The drug is available in various dosages of 5 mg and 10 mg suitable for different ages and patient preferences.

The main therapeutic effects of Cetirizine Hydrochloride are achieved by blocking or reducing the activity of histamine. This natural substance is responsible for the manifestation of allergic reactions in the human body.

The clinical effectiveness of Zyrtec has been confirmed by numerous studies. This new generation medicine:

  • Minimizes or eliminates allergy symptoms;
  • Helps in the first phase or when an allergy attack has already begun;
  • Provides an anti-inflammatory effect.

Indications for use

Zyrtec may be prescribed in accordance with its licensed indications to people over 6 years of age, suffering from:

  • Chronic (lasting more than 6 weeks) urticaria;
  • Allergic rhinitis of any type (perennial, occupational or seasonal).

Treatment regimens and dosages

Zyrtec is for oral use only.

  • Typical dosage regimen: A 10 mg tablet approximately every 24 hours;
  • Dosage for patients over 6 years of age: A 5 mg tablet twice a day;
  • Dosage regimen for mild symptoms: A 5 mg tablet approximately every 24 hours.

Recommendations for use

To get the most out of the treatment, follow these guidelines:

  • Don't miss taking pills, one dose of 10 mg is enough for 24 hours;
  • Take regular doses at the same time every day;
  • Zyrtec can be taken at any time of the day;
  • If you have a sedative effect (such as weakness), take the tablets in the evening;
  • Don't chew or crush tablets before taking them.

Patients with moderate or severe renal impairment may be given a dose of Zyrtec 5 mg every 24 or 48 hours.

Missed Dose

Take the missed tablet as soon as you remember, skip the dose if it is almost time for the next dose.


Don't take Zyrtec without consulting a doctor, if you have or have had the following:

  • Glaucoma;
  • Emphysema;
  • Respiratory problems;
  • Impaired liver or kidney function;
  • Problems with urination.

Be careful if you drive a car until you know how the medicine affects you.

Usually, Zyrtec tablets are not recommended for children under 6 years of age, as this dosage form (tablets) does not allow to adjust the dose.

Use of Zyrtec during pregnancy

  • Dryness in the throat or mouth;
  • Itchy, sore throat;

Important specificity! Zyrtec has a lower risk of pronounced sedative effects (such as fatigue and drowsiness) compared to first-generation H1 antihistamines (for example, Clemastine).

    I took Zyrtec for 3 allergy seasons. The first and second years were great, the drug was the solution to all my problems. In the last year, I relaxed a little and did not take pills every day. Because of this, I had a runny nose and itching in the eyes. I increased the dose to 20 mg per day and immediately got nausea, which worsened within 1.5 hours. My verdict: it is a great product but you should take it RIGHT.

    Runny nose and red eyes are not even my number one problem, it's strange how differently allergies affect people. Allergies make me very tired and give me a lot of headaches. I give Zyrtec 5 stars because of all the allergy medications it works best.

    As for me, it suits me not only by its action, but also by price. I buy only Zyrtec and so far I am satisfied with everything. The drug works great, saves both with seasonal allergies and in emergency cases. On the plus side, it doesn't cause drowsiness.
