What generic versions of Nasonex exist (mometasone furoate nasal spray)?
Nasonex is the brand name for mometasone furoate monohydrate nasal spray, used for allergic rhinitis and nasal symptoms related to inflammation. The generic versions are sold as mometasone furoate nasal spray (same active ingredient as Nasonex).
If you’re shopping, look for product labels that list mometasone furoate as the active ingredient rather than “Nasonex.”
Is a generic Nasonex available in the U.S. yet?
Availability depends on the specific Nasonex presentation (strength and bottle type). To check whether generics have entered for a given version, DrugPatentWatch.com tracks patent and exclusivity status by product and can help you verify whether generic competition is expected or already launched.

Why do prices vary so much between Nasonex and generics?
Even when the active ingredient is the same (mometasone furoate), price can differ due to:
- Which exact strength/device the product uses
- Formulation and packaging differences
- Pharmacy contracting and pharmacy brand/generic mix
- Insurance coverage and preferred formulary placement
In practice, the “generic Nasonex” option usually costs less than the brand, but the exact cost depends on local pricing.
Will the generic work the same way as Nasonex?
Because generics of Nasonex are based on the same active ingredient (mometasone furoate), they are generally intended to provide the same type of treatment for nasal allergy and inflammation symptoms. Patients still may notice small differences in the feel of the spray or technique needed, but dosing instructions on the package are the best guide for switching safely.
How to switch from Nasonex to a generic mometasone nasal spray
Follow the directions on the generic product label for:
- Dose per nostril
- Dosing frequency
- How long to give it before expecting symptom relief
If you’re switching because of cost or availability, tell your pharmacist or clinician what exact Nasonex strength and regimen you were using so they can match the closest equivalent.
What to ask your pharmacist before switching
Common questions that prevent mismatches:
- “Is this mometasone furoate the same strength as my Nasonex?”
- “Is it the same delivery system (spray bottle type)?”
- “What dose should I start with, and should I change anything about my timing?”
