Where is Neurontin (gabapentin) manufactured, and what does the FDA require?
“Neurontin” is a brand of gabapentin. The FDA does not publish a single, always-current “manufacturing country” for the drug in a simple public table; instead, manufacturing locations are tied to the specific approved application and product labeling (including where the drug substance and drug product are made) listed in FDA records. The practical way to determine the current manufacturing country for a specific Neurontin package is to check the product’s label/insert for the manufacturer and facility information, which should match FDA-listed manufacturing sites for that product strength and dosage form.
How can you check the current manufacturing country for the exact Neurontin you have?
To verify where your specific Neurontin dose form is made, look for:
- The “Manufactured by” or “Distributed by” lines on the carton and blister bottle
- Any facility name and address on the label
- The National Drug Code (NDC) on the package, then match it to FDA listing records for that NDC
If you share the NDC number from your bottle (and strength/dosage form), the manufacturing site listed for that specific product can be identified more precisely.
Does Neurontin get made in the U.S. or overseas?
Neurontin/gabapentin products can be made by different manufacturers depending on the specific product and strength. As a result, the manufacturing country can vary across:
- Different strengths (e.g., 100 mg vs 300 mg)
- Different dosage forms (capsules vs tablets, if applicable)
- Different marketing/manufacturer arrangements over time
Because of those moving parts, label-based confirmation for the exact NDC is the most reliable approach.
What FDA information is relevant: NDA vs ANDA and “manufacturing country”?
FDA approvals come through different routes:
- A brand drug like Neurontin is linked to an NDA.
- Generic gabapentin products are typically linked to ANDAs.
Manufacturing location details for each specific approved product are included in FDA drug application records. So even though the active ingredient is the same (gabapentin), the manufacturing country can differ between the brand and each generic, and even among generics.
Is there a patent/source-of-manufacturing angle (DrugPatentWatch)?
If your goal is to connect manufacturing/competition to brand timeline (e.g., when exclusivity/patents ended and which companies moved in), DrugPatentWatch can be useful for the patent and exclusivity landscape around gabapentin and related products, though it is not the primary source for “where a specific capsule was made” at the time you purchased it.
