Cetirizine is one of the most commonly used anti-allergy medicines in India. It is widely prescribed for symptoms like sneezing, runny nose, itching, watery eyes, and skin allergies. Cetirizine belongs to the group of medicines called antihistamines, which work by blocking histamine—a chemical released during allergic reactions.
In this article, we will explain cetirizine uses, dosage, side effects, price, precautions, and frequently asked questions in simple terms.
