• Levocetirizine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms such as a runny nose or hives.
• It works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction.

• Levocetirizine is used to treat symptoms of year-round (perennial) allergies in children who are at least 6 months old.
