Generic Zyrtec

–

Cetirizine is an antihistamine used to treat allergies. It blocks histamine, a chemical responsible for allergy symptoms like sneezing, itching, and watery eyes. Unlike first-generation antihistamines, cetirizine causes less drowsiness and provides long-lasting relief for up to 24 hours. It is available in tablets, syrup, and chewable forms, making it convenient for both adults and children.
