Levocetirizine

Levocetirizine is a prescription antihistamine used to help relieve allergy symptoms. It works by blocking histamine, a natural substance in the body that can trigger sneezing, runny nose, watery eyes, and itching.

It is commonly used for seasonal and year-round allergies and may also help with hives. It can cause drowsiness in some people, so avoid alcohol and be careful when driving or using machinery until you know how it affects you. Follow your prescriber’s directions, especially if you have kidney problems or take other medicines that may cause sleepiness.
