Introduction to Cetirizine

Cetirizine is a popular antihistamine widely used to treat symptoms associated with allergies and hay fever. As a second-generation antihistamine, cetirizine causes less drowsiness compared to first-generation antihistamines, making it an appealing choice for those needing day-time symptom relief.

How Does Cetirizine Work?

Cetirizine blocks the effects of histamine, a chemical produced by the immune system during an allergic reaction. By reducing the impact of histamine, it helps control symptoms such as itching, swelling, and rashes.
