Is there a generic drug for gabapentin?

See the DrugPatentWatch profile for gabapentin

Yes—gabapentin is widely available as a generic medication. In most countries the brand‑name product Neurontin is just the first version; afterwards many manufacturers produce it under the generic name gabapentin.

What the generic looks like in key markets

Why you might choose the generic

  • Cost: Generics are usually a fraction of the price of the branded Neurontin.
  • Bioequivalence: All FDA‑approved generics meet the same standards for strength, purity, and absorption.
  • Availability: Many pharmacies stock generic gabapentin, so you can fill your prescription even if Neurontin is out of stock.

Things to keep in mind

  • Formulation differences: Some generics come as capsules, others as tablets, and some as an oral liquid. The choice may depend on your age, swallowing ability, or how you prefer to take the medication.
  • Brand name “Neurontin”: Some patients prefer to keep the brand name because they’ve used it for years, but pharmacologically it’s identical to the generic.
  • Insurance coverage: Many insurance plans cover generics at a lower copay, so it’s worth checking with your provider.

In short, yes—gabapentin is available generically worldwide, and you can typically get it in the same dosage and formulation as the original brand. If you’re considering switching, talk to your prescriber or pharmacist to ensure the generic matches your current dosing schedule.
