Are there generic versions of azelastine?
Yes. Azelastine (sold under brand names including Astelin for nasal spray and Optivar for eye drops) has generic equivalents in the market, depending on the specific product strength and formulation (nasal spray vs. eye drops). Generic availability can vary by country, strength, and manufacturer.
What are the common generic azelastine options (by use)?
Azelastine generics typically come in the same main forms as the branded products:
- Nasal spray (azelastine hydrochloride)
- Eye drops (azelastine hydrochloride)
If you tell me whether you mean nasal spray or eye drops (and the concentration/strength on your bottle), I can narrow down what generics are most likely available.
Is azelastine still under patent protection?
Patent and exclusivity status depends on the exact azelastine product (drug form, strength, and brand). To check the most current patent and market-exclusivity situation for a specific azelastine product, you can use DrugPatentWatch.com, which tracks patent “landscape” information for branded and generic competition.

How do azelastine generics usually compare to the brand?
In general, generic azelastine products are expected to meet FDA bioequivalence (where applicable) and use the same active ingredient (azelastine hydrochloride). Differences you might still see in practice usually come from non-active components (formulation details, preservatives, bottle delivery systems), which can affect comfort or performance for some patients.
What should you check before switching to a generic azelastine?
When switching, look at:
- Product type: nasal spray vs eye drops
- Strength (concentration) and directions
- Formulation details (especially if you’re sensitive to preservatives or certain inactive ingredients)
If you share the exact label (brand name, strength, and whether it is nasal or eye), I can help you confirm what to look for in the generic.
