Zyrtec prevents sneezing, runny nose, itching and watering of the eyes

Drug Uses

Zyrtec is an antihistamine. Antihistamines prevent sneezing, runny nose, itching and watering of the eyes, and other allergic symptoms. Zyrtec is used to treat allergies, hives (urticaria), and other allergic inflammatory conditions.

How Taken

Zyrtec comes as a tablet to take it orally. It usually is taken once a day. It may be taken regularly or when allergy symptoms flare up. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Zyrtec exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Warnings/Precautions

Zyrtec is in the FDA pregnancy category B. This means that it is unlikely to harm an unborn baby. Do not take Zyrtec without first talking to your doctor if you are pregnant. Zyrtec passes into breast milk and may affect a nursing baby. Do not take Zyrtec without first talking to your doctor if you are breast-feeding a baby.
