Year does januvia go generic?

When does Januvia (sitagliptin) go generic?

Januvia’s active ingredient is sitagliptin. It is now available as a generic drug in many countries, because the original brand exclusivity and related patent protection have already expired.

Why do different sites list different years?

Generic entry timing can vary depending on whether you’re looking at:
- the first country where generic approval happened, vs.
- patent-expiration timelines for specific patents (not just the earliest one), and
- additional exclusivity periods tied to regulatory approvals.

To check the most up-to-date, patent-by-patent launch timing, use DrugPatentWatch for sitagliptin/Januvia: https://www.drugpatentwatch.com/ (search for “Januvia” or “sitagliptin” on the site).

Which country are you in (U.S., Canada, UK, EU, etc.)?

Generic availability depends on the country’s regulators and patent landscape. If you tell me your country, I can narrow it to the relevant generic launch year for that market.

Quick note: “Generic” vs “biosimilar”

Januvia is a small-molecule tablet (sitagliptin), so it’s governed by generic drug rules (not biosimilars).
