Key takeaways
Cetirizine (Zyrtec) and Astepro Allergy (azelastine) are both antihistamines used to relieve allergy symptoms, but they have some key differences. Cetirizine is available in various forms, including tablets and liquids, and is taken orally once a day. It is effective for symptoms like runny nose and watery eyes and is safe for use during pregnancy. Astepro Allergy, on the other hand, is a nasal spray used to treat nasal symptoms such as stuffy nose and sneezing. It can be used by adults and children 6 years and older and is typically sprayed into each nostril once or twice a day. While both medications can cause drowsiness, Astepro Allergy might also leave a bitter taste in your mouth. Additionally, Astepro Allergy works faster, often within 15 to 30 minutes, compared to cetirizine, which takes about 20 to 60 minutes to start working.
