What is cetirizine?
Cetirizine is a non-sedating antihistamine that is commonly used to alleviate allergy symptoms. It belongs to a class of drugs called second-generation antihistamines, which are known for their effectiveness in reducing symptoms such as itching, sneezing, and runny nose. Cetirizine works by blocking the action of histamine, a chemical that is released by the body during an allergic reaction. By doing so, it helps to alleviate the discomfort and irritation caused by allergies. Unlike older antihistamines, cetirizine is less likely to cause drowsiness, making it a preferred choice for many individuals.

When you take cetirizine, it prevents histamine from binding to its receptors, which helps to alleviate the discomfort and irritation caused by allergies. Unlike older antihistamines, cetirizine is less likely to cause drowsiness, making it a preferred choice for many individuals. It is important to note that cetirizine does not cure allergies, but it can provide effective relief from their symptoms.
