Is isosorbide mononitrate available as a generic?
Yes. Isosorbide mononitrate is widely available as a generic medicine in many markets because the active ingredient’s key patent protections are long expired. Generic versions are sold under the chemical name “isosorbide mononitrate” by multiple manufacturers.
What should you look for when buying generic isosorbide mononitrate?
Generic isosorbide mononitrate products should match the branded drug in key ways, but the exact look and dosing options can differ by manufacturer. Pay attention to:
- Strength (for example, common tablet strengths vary by product line)
- Dosage form (immediate-release vs extended-release, depending on what you were prescribed)
- How often you take it (driven by the formulation and your prescription)
Is there a specific brand you mean?
In many countries, “isosorbide mononitrate” is the generic name, while brands differ. If you tell me the brand name you saw (or the country you’re in), I can help you narrow down which generic equivalents typically correspond to that product.

Any safety or switching issues with generics?
With nitrate medicines like isosorbide mononitrate, switching usually shouldn’t be a problem when you keep the same strength and the same release type (extended-release vs immediate-release). The main practical risks with changing brands are taking the wrong formulation or the wrong dosing frequency. If you share the exact product label (strength + IR/ER), I can help you verify whether two options look equivalent.
