What is Cetirizine

Cetirizine is the active metabolite of hydroxyzine, a piperazine H1-receptor antagonist (H1-blocker). Cetirizine differs from the parent compound by having greater affinity for the H1-receptor.

Cetirizine is commercially available as oral, ophthalmic, and injectable formulations. The ophthalmic solution is indicated to treat ocular pruritus associated with allergic conjunctivitis.

Oral cetirizine is approved for allergic rhinitis and chronic idiopathic urticaria.

In addition, oral cetirizine has been used off-label in pediatric patients for symptomatic treatment of atopic dermatitis.

Cetirizine intravenous injection is used to treat acute urticaria in adults and children 6 months of age and older.

At recommended doses, cetirizine may cause a higher incidence of somnolence than the non-sedating antihistamines (e.g., loratadine), although to a much lesser degree than first-generation (sedating) antihistamines.

Like loratadine, the cardiovascular safety of cetirizine has been demonstrated in drug-interaction studies, elevated-dose studies, and clinical trials.
