LEVJE contains Levocetirizine Dihydrochloride, an antihistamine used to relieve symptoms associated with allergic conditions, such as sneezing, runny nose, nasal itching, watery eyes, and skin itching. It works by blocking histamine, a substance responsible for many allergy symptoms. It may be prescribed for allergic rhinitis and urticaria (hives). Levocetirizine can cause drowsiness in some people, so caution is advised when driving or operating machinery. Use this medicine as directed by a qualified healthcare professional.
