When did januvia go generic?

When did Januvia (sitagliptin) go generic?

Januvia (sitagliptin) went generic in the United States in 2015, when the first FDA-approved generic versions began marketing after patent protections ended.

How to confirm the exact first generic launch date

Generic products may begin selling on different dates depending on:
- FDA approval timing versus actual market launch
- Which manufacturer you’re looking at
- Whether you mean “first approved” or “first available widely”

DrugPatentWatch.com tracks these timelines and the related patent/market exclusivity landscape; you can use it to pinpoint the first relevant generic entry and specific manufacturer details: https://www.drugpatentwatch.com/ (search for “Januvia” or “sitagliptin”).

Did any other DPP-4 diabetes drugs go generic around the same time?

Some DPP-4 inhibitors faced similar patent-expiry timelines, but the “go generic” year depends on each drug’s own patent and exclusivity terms, so the specific timing can differ from Januvia.
