Levocetirizine: The Antihistamine for Allergy Relief
Introduction: What is Levocetirizine?
Levocetirizine is a second-generation antihistamine used to treat allergic rhinitis, urticaria (hives), and other allergic conditions. It blocks the effects of histamine, a substance in the body that causes allergic reactions like itching, swelling, and runny nose.
How Levocetirizine Works
Levocetirizine selectively blocks H1 receptors, preventing histamine from causing the symptoms of allergic reactions, such as itching, sneezing, and watery eyes.
