Cetirizine dihydrochloride is the active substance in Tezastin. Tezastin is an antiallergic medicine.
In adults and children aged 6 years and older, Tezastin 10 mg film-coated tablets are indicated:
- for the treatment of nasal and ocular symptoms of seasonal and perennial allergic rhinitis.
- for the treatment of urticaria.
2. What you should know before taking Tezastin
Do not take Tezastin:
- if you have severe kidney disease requiring dialysis;
- if you are allergic to cetirizine dihydrochloride or to any of the other ingredients of this medicine (listed in section 6), to hydroxyzine, or to piperazine derivatives (active substances of other closely related medicines).
Warnings and precautions
Talk to your doctor or pharmacist before taking Tezastin.
If you are a patient with renal impairment, consult your doctor; if necessary, you should take a lower dose. Your doctor will determine the new dose.
Consult your doctor if you have problems urinating (in conditions such as spinal cord injury or bladder or prostate problems).
If you are an epileptic patient or at risk of seizures, you should consult your doctor.
No clinically significant interactions have been observed between alcohol (at blood levels of 0.5 per mille (g/l), corresponding to one glass of wine) and cetirizine used at recommended doses. However, there are no available data on the safety of concomitant use of higher doses of cetirizine and alcohol. Therefore, as with all antihistamines, it is recommended to avoid taking Tezastin together with alcohol.
If you need to undergo an allergy test, ask your doctor whether you should stop taking Tezastin a few days before the test. This medicine may alter the results of allergy testing.
Children
Do not give this medicine to children under 6 years of age, as the tablet formulation does not allow for the necessary dose adjustments.

Tezastin should be avoided during pregnancy. Accidental use of the medicine by a pregnant woman does not produce harmful effects on the fetus; however, the medicine should be taken only if necessary and under medical advice.
Cetirizine passes into breast milk. A risk of adverse effects in breastfed infants cannot be excluded. Therefore, you should not take Tezastin while breastfeeding unless you have consulted your doctor.
