Histamine is a chemical mediator released during allergic reactions, leading to symptoms such as itching, swelling, and increased mucus production. By binding to H1 receptors, levocetirizine prevents histamine from exerting its effects, thereby alleviating allergy symptoms. The medication is available in various formulations, including 5 mg tablets, which are commonly prescribed for adults and children above 6 years of age.
