Antihistamine/Decongestant Combination (About this – PubMed Health)
Uses of This Medicine
Cetirizine and pseudoephedrine is a combination of an antihistamine and a decongestant used to treat the symptoms of seasonal or yearly allergies. Antihistamines work by preventing the effects of a substance called histamine, which is produced by the body. Histamine can cause itching, sneezing, runny nose, and watery eyes. Decongestants produce a narrowing of blood vessels. This leads to clearing of nasal congestion, but it may also cause an increase in blood pressure in patients who have high blood pressure.
This medicine is available without a prescription.
Do not give any over-the-counter (OTC) cough and cold medicine to a baby or child under 4 years of age. Using these medicines in very young children might cause serious or possibly life-threatening side effects .
