Cetrine is an antihistamine used to treat symptoms of allergic reactions, such as runny nose, stuffy nose, red eyes, itching, and hives. It may also help with insect bites, atopic dermatitis, and other allergic conditions. Cetrine works by blocking the action of histamine, which is a substance that causes allergy symptoms. It is usually available in tablet form.
Cetrine is an antihistamine for systemic use for the symptomatic treatment of allergic rhinitis (including perennial allergic rhinitis) and urticaria.

The drug can be taken regardless of food intake.
Recommended doses:
Patients with intermittent allergic rhinitis (symptoms present for less than 4 days per week or less than 4 weeks per year) should be treated according to the course of the disease and the history: treatment can be stopped if the symptoms disappear and can be resumed if the symptoms recur. In case of persistent allergic rhinitis (symptoms present for more than 4 days per week or more than 4 weeks per year), the patient can be offered continuous therapy during the period of contact with allergens. There is clinical experience with levocetirizine for a treatment period of at least 6 months. In chronic diseases (chronic allergic rhinitis, chronic urticaria), the duration of treatment is up to 1 year (data are available from clinical studies using the racemate).
If necessary, the use of levocetirizine during pregnancy may be considered.
Caution should be exercised when prescribing levocetirizine to breastfeeding women.
The use of levocetirizine in children under 2 years of age is not recommended due to limited data in this age group.
The drug should be used in children over 2 years of age.
Patients who intend to drive, engage in potentially hazardous activities, or operate machinery should take into account their reaction to the drug.
Symptoms: Symptoms of overdose may include drowsiness in adults and initial agitation and increased irritability followed by drowsiness in children.
Treatment. There is no specific antidote for levocetirizine. In case of symptoms of overdose, symptomatic and supportive therapy is recommended. Gastric lavage should be considered shortly after ingestion. Hemodialysis is not effective in removing levocetirizine from the body.
Interaction studies (including studies with CYP3A4 inducers) have not been conducted with levocetirizine. Studies with cetirizine (racemate) have shown that concomitant use with antipyrine, azithromycin, cimetidine, diazepam, erythromycin, glipizide, ketoconazole or pseudoephedrine does not cause clinically significant adverse interactions. With concomitant use with theophylline (400 mg daily), a small decrease (by 16%) in the total clearance of levocetirizine was observed (theophylline distribution was not changed). In a study of multiple doses of ritonavir (600 mg twice daily) and cetirizine (10 mg daily), the extent of cetirizine exposure increased by approximately 40%, while the distribution of ritonavir was slightly changed (-11%) with concomitant use of cetirizine.
Eating does not affect the extent of absorption of the drug, but reduces the rate of its absorption.
Concomitant use of cetirizine or levocetirizine and alcohol or other central nervous system depressants in susceptible patients may cause additional impairment of alertness and ability to perform work.
Store in original packaging at a temperature not exceeding 30 ° C. Keep out of the reach of children.
