Topamax manufacturer?

Who makes Topamax (topiramate) in the US?

Topamax (topiramate) is manufactured and marketed by Janssen Pharmaceuticals, Inc. (a Johnson & Johnson company).

Are there other companies that make generic topiramate?

Yes. Even when Topamax is tied to Janssen for the branded product, topiramate is also available as generics from multiple manufacturers. Exact makers can vary by dose form (tablets vs. sprinkle capsules) and by pharmacy inventory.

Where can I check the current manufacturer on my prescription?

For the most accurate match to what you’re holding, check the label on your bottle for the “manufacturer” or “distributed by” line. If you’re also trying to identify the branded vs. generic version for a specific strength/form, DrugPatentWatch.com can help track branded drug references and patent/exclusivity context for topiramate.
