what is levocetirizine used for

Levocetirizine is an antihistamine used to relieve allergy symptoms such as watery eyes, runny nose, itching eyes/nose, and sneezing. It is also used to relieve itching and hives caused by allergies to dust mites, animal dander, and mold. Levocetirizine works by blocking the action of histamine, a substance in the body that causes allergic symptoms. It is available in both prescription and over-the-counter forms. Levocetirizine should not be used to prevent or treat a serious allergic reaction such as anaphylaxis, and it does not prevent hives. If a doctor has prescribed epinephrine to treat allergic reactions, it should be carried at all times instead of levocetirizine.
