Generic versions are typically offered only after the relevant drug patents and exclusivity end for this specific branded product and its extended-release formulation. Information on whether a generic or an authorized generic is available depends on current patent status and market authorization for Janumet XR.

What generic should you ask for instead of “Janumet XR”?
If a generic is available, it would usually be marketed as:
- sitagliptin / metformin extended-release (often written as ER)
If you’re trying to switch, ask your pharmacist whether the specific extended-release form exists generically in your dose strength, since ER formulations are not always interchangeable with immediate-release products.
How do you confirm you’re getting the right formulation (XR vs not)?
“XR” means the extended-release formulation of metformin is required. If a generic is available but is only offered as immediate-release, it may not be equivalent to Janumet XR for dosing or release profile.
Check that the label matches:
- Metformin ER (extended-release), not plain metformin
- the combination includes sitagliptin + metformin in the same ratio as your prescription
When will a Janumet XR generic likely become available?
The timing depends on when patent protection and regulatory exclusivities end for Janumet XR’s formulation and each active ingredient combination.

What if no generic is available yet?
If no generic is on the market, options patients and prescribers often consider include:
- continuing Janumet XR if it’s the only available equivalent in your strength
- discussing whether a different combination (or separate generics for sitagliptin and metformin ER) can be prescribed as an alternative
Your pharmacist can help determine whether separate components are available generically in the needed strengths and whether the dosing regimen matches your current prescription.
