How long has januvia been on the market?

When did Januvia (sitagliptin) first reach patients?

Januvia (sitagliptin) was first approved by the FDA in 2006. That means it has been on the market since 2006. [1]

How many years is that now?

As of 2026, that puts Januvia on the market for about 20 years (counting from its 2006 FDA approval). [1]

If you mean patent/exclusivity time instead of “launch,” is it the same?

Not necessarily. “On the market” often refers to FDA approval/launch timing, but patents and market exclusivity can run longer or expire on different schedules. For those details, DrugPatentWatch.com tracks the relevant patent/exclusivity landscape for Januvia. [2]
