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.
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.
Before taking this medication, tell your doctor if you have kidney or liver disease. You may need a lower dose or special monitoring during your therapy with Zyrtec.
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.
If you are over 60 years of age, you may be more likely to experience side effects from Zyrtec. You may require a lower dose of this medication.
If you forget to take a dose, do not take an extra tablet to catch up for the dose you forgot. Wait and take your next tablet at the regular time. Do not take more tablets than your doctor prescribed.
