Zyrtec vs. Astelin Drug Summary
Zyrtec
Zyrtec (cetirizine) is a second-generation oral antihistamine that blocks histamine to relieve sneezing, itching, and hives. It comes as tablets, chewables, capsules, or syrup and is taken once a day, with dosing sometimes adjusted for kidney or liver function.
Astelin
Astelin (azelastine) is an antihistamine delivered as a nasal spray that works directly in the nasal passages to reduce sneezing, congestion, and runny nose. It's used twice daily, with one or two sprays per nostril depending on symptom severity.
