Cetirizine

Cetirizine is an antihistamine medicine used to help relieve allergy symptoms. It works by blocking histamine, a natural substance your body releases during an allergic reaction.

It is commonly used for seasonal and year-round allergies, hives, sneezing, runny nose, itchy eyes, and itching. Follow the label or your clinician’s directions, and use extra caution if you have kidney disease, are pregnant, or take other medicines that may cause drowsiness.
