Zyrtec (Cetirizine): Uses, Dosage, Side Effects, and More

From:

Price range: $8.64 through $25.49

Zyrtec (cetirizine hydrochloride) is an antihistamine used to relieve allergy and hay fever symptoms such as sneezing, runny nose, itchy eyes, and throat irritation. It also treats chronic hives and allergic skin itching by blocking histamine, the chemical responsible for allergic reactions. Providing up to 24-hour relief, Zyrtec is generally less sedating than older antihistamines, though mild drowsiness may occur.
