About Cetirizine+dextromethorphan+phenylephrine
Cetirizine+dextromethorphan+phenylephrine is a medicine used to relieve symptoms of the common cold, allergies, and upper respiratory tract infections. It helps ease a dry cough, clear a blocked nose, and reduce allergy symptoms like a runny nose, sneezing, and watery eyes. This combination medication provides temporary relief so you can rest and recover comfortably.
For best results, take it exactly as directed by your doctor, usually spaced evenly throughout the day while symptoms last.

However, if you experience serious side effects like a fast heartbeat, severe dizziness, or difficulty urinating, stop taking the medicine and consult your doctor immediately.
Talk to your doctor before starting it if you have liver damage, kidney issues, diabetes, thyroid disease, or an enlarged prostate.

Avoid drinking alcohol while taking it because it can increase drowsiness and impair your alertness. Let your doctor know if you are taking any other sedatives, blood pressure medicines, or antidepressants to prevent harmful drug interactions. If you are pregnant, breastfeeding, or an older adult, consult your doctor or pharmacist before using this medicine to ensure it is safe for you.

Cetirizine+dextromethorphan+phenylephrine contains a combination of three medicines: Cetirizine (an antihistamine/antiallergic), Dextromethorphan (a cough suppressant), and Phenylephrine (a nasal decongestant).

It helps relieve cold or allergy symptoms such as sneezing, a runny nose, watery eyes, itching, swelling, or congestion.
