Zyrtec (Cetirizine)

Zyrtec (cetirizine) is an antihistamine medication used to treat allergy symptoms such as sneezing, runny nose, itchy or watery eyes, and itching caused by hay fever, allergies, or hives. It works by blocking histamine, a substance in the body that triggers allergic reactions. Zyrtec is usually taken once daily and starts working within an hour, providing relief for 24 hours. It’s generally well-tolerated, but some people may experience side effects like dry mouth, fatigue, or dizziness. Always use as directed and consult a healthcare provider if you have any concerns or underlying health conditions.
