Gabapentin is available both as a brand‑name drug (most commonly Neurontin®) and in a wide range of generic versions. Here’s a quick snapshot of the key manufacturers that produce it:
| Brand/Generic | Original/Brand‑name Manufacturer | Common Generic Manufacturers |
|---------------|----------------------------------|------------------------------|
| Neurontin® | Pfizer (original patent holder) | – |
| Generic gabapentin | – | Teva Pharmaceuticals, Mylan (now part of Viatris), Sandoz (Bayer), Cipla, Sun Pharma, Dr. Reddy’s, Aurobindo Pharma, GSK (through its generics arm), Amneal, and many other specialty and regional companies |
How to identify the manufacturer on your medication
- Brand name: Look for “Neurontin” on the label—this is Pfizer’s product.
- Generic name: The label will read “gabapentin.” Below the dosage, you’ll usually see a manufacturer’s name or an imprint (e.g., “Teva,” “Mylan,” “Cipla”). In the U.S., the FDA’s Drug Enforcement Administration (DEA) also tracks manufacturer information, which you can look up using the drug’s National Drug Code (NDC).
Why so many manufacturers?
Gabapentin is a generic, off‑patent drug (the original patent expired in the 1990s). Once a drug becomes generic, many pharmaceutical companies are free to manufacture and sell it, provided they meet regulatory standards (e.g., FDA approval in the U.S., EMA approval in Europe). This competition keeps prices lower and makes the medication widely accessible.
Checking the specific manufacturer
If you need to know exactly who made the specific bottle you’re taking—whether for insurance, side‑effect concerns, or regulatory reasons—use one of these approaches:
1. Check the bottle: The manufacturer’s name is printed near the drug name and NDC.
2. Use the NDC: Enter the 10‑digit NDC in the FDA’s NDC search tool (https://www.fda.gov/drugs/drug-approvals-and-databases/national-drug-code-database).
3. Ask your pharmacist: Pharmacists can pull the exact manufacturer from the pharmacy’s dispensing record.

Bottom line: While Pfizer originally made Neurontin, the generic version of gabapentin is now produced by a large number of reputable pharmaceutical companies worldwide. The specific manufacturer can be found on your medication label or by checking the NDC.
