Xyzar Levocetirizine 5mg Tablets are an antihistamine used to relieve allergy symptoms such as runny nose, sneezing, itching, and watery eyes, as well as itching and swelling caused by hives. Levocetirizine, the active ingredient, works by blocking histamine, a substance in the body that triggers allergic reactions. These tablets are non-sedating, meaning they provide relief without causing drowsiness, making them ideal for daytime use. Xyzar is effective in treating both seasonal and year-round allergies and helps improve overall comfort for those with allergic conditions.
