Cetirizine is a second-generation antihistamine used to treat allergic conditions such as hay fever, urticaria, and allergic rhinitis. It works by blocking histamine H1 receptors without causing significant drowsiness, a common side effect of first-generation antihistamines. It has a rapid onset of action and a long duration, often allowing once-daily dosing. It is well-tolerated and suitable for both adults and children.
