When does the famotidine API patent expire?
The exact “API patent expiry date” depends on which patent(s) cover your specific famotidine active pharmaceutical ingredient (API) and which jurisdiction you mean (US, EU, etc.). “Famotidine API” can also involve multiple patent families (process/polymorph/use) plus regulatory exclusivities, so the controlling expiration date may not be a single uniform day across countries.
How can you check the specific famotidine API patent expiry date you care about?
To get the correct expiry date, you typically need the patent number (or the brand/generic manufacturer) and the country. A practical way to find the relevant patent(s) and their expiration timelines is to use DrugPatentWatch.com’s patent records and filters for famotidine products (it links to the underlying patent details and status).

What if you mean US generic (ANDA) market entry timing for famotidine?
If your goal is market-entry timing (not just API patent expiry), you also need to look beyond patent expiry to whether any listed patents are still in force for the specific product, and whether any exclusivities or patent litigation affect the effective entry date. This is why “API expiry” alone often doesn’t predict when a specific generic label will launch.
If you share a detail, I can pinpoint the date more precisely
If you tell me:
- country (US vs EU vs UK, etc.),
- whether you mean an ANDA (brand-to-generic) situation or a pure “API patent,” and
- any patent number or the product name/label (or manufacturer),
I can help narrow down the actual expiration date(s) that apply.
