Key takeaways
Azelastine nasal spray, available as both Astepro Allergy (over-the-counter) and a prescription version, is an antihistamine used to treat nasal symptoms due to allergies, such as a runny or stuffy nose. Both versions work by blocking histamine to relieve these symptoms. However, there are some differences between the two. Astepro Allergy is available over-the-counter in a 0.15% strength and is suitable for adults and children 6 years and older. The prescription version comes in both 0.1% and 0.15% strengths and can also treat non-allergic nasal symptoms. The prescription version is available as a lower-cost generic, while Astepro Allergy is branded. Both forms can cause side effects like a bitter taste and nasal discomfort, but the prescription version has a higher incidence of side effects like headaches and sleepiness. Additionally, the prescription version may require more frequent dosing, typically twice a day, compared to the once or twice daily dosing of Astepro Allergy.
