What is the difference between Zyrtec and primalan syrup?

Zyrtec (cetirizine) is an antihistamine used primarily to relieve allergy symptoms such as sneezing, runny nose, and itching. Primalan syrup (promethazine) is also an antihistamine but is often used for its sedative effects and to treat nausea or motion sickness. While both medications can address allergy symptoms, Zyrtec tends to have a more targeted approach for Allergies, whereas Primalan may cause drowsiness and is used in different contexts. Always consult a healthcare provider for specific recommendations based on individual health needs.
