Does gabapentin have a generic version?
Yes. Gabapentin is available as a generic medicine. It is sold under the generic name “gabapentin,” and many brands exist for the same active ingredient. (Source: FDA Orange Book listing for gabapentin products) [1]
How can I tell if my gabapentin is generic?
You can check the label or pharmacy information:
- If the active ingredient listed is “gabapentin,” it’s generic (even if a brand name is printed for the product).
- If it’s “gabapentin” with no brand-specific active ingredient, it’s the generic drug.

Are there different generic versions (different manufacturers)?
Yes. Multiple companies market generic gabapentin, which can differ by manufacturer, formulation, or dosage strength, but they share the same active ingredient. (Source: FDA Orange Book listings) [1]
Is any of it not interchangeable?
Generic availability does not automatically mean every product is identical in use. Some forms (such as extended-release vs. immediate-release) are different products even if both use gabapentin. Your prescriber or pharmacist can confirm which version you have. (Source: FDA Orange Book classifications by product) [1]
