cetirizine

Cetirizine is an antihistamine medication used to relieve allergy symptoms such as sneezing, runny nose, itchy or watery eyes, and itching caused by hay fever or other allergies. It works by blocking the effects of histamine, a substance your body releases during allergic reactions, thereby reducing discomfort. Cetirizine is typically taken once daily and is available over-the-counter. It usually causes drowsiness less often than older antihistamines, making it a convenient option for allergy relief. However, some people may still experience dizziness or dry mouth, so it's important to follow dosing instructions and consult a healthcare professional if needed.
