What are “metformin names” (brand and generic names)?
Metformin is the generic name for a diabetes medicine. “Metformin names” usually refers to the different brand names and formulations sold in different countries, plus the common way it’s written on prescriptions (including whether it’s immediate-release or extended-release).
Common metformin brand names people look for
In many markets, metformin is sold under well-known brand names such as Glucophage and Glucophage XR, and under local brands that vary by country.
Do different metformin versions have different names (IR vs XR)?
Yes. Prescriptions often specify the formulation:
- Immediate-release metformin is often labeled without an “XR” suffix.
- Extended-release metformin is commonly labeled “XR” (or similar country-specific wording).
Because brand naming varies by manufacturer and country, the safest way to match the “metformin name” you saw is to check the exact label text and whether it says immediate-release or extended-release.
How to identify which metformin you have from the label
Look for the active ingredient line (it should say “metformin” with a specific formulation like immediate-release/extended-release) and the dosage (for example, 500 mg, 850 mg, or 1000 mg). That will distinguish it even when the brand name changes.
Want the metformin names for your country?
If you tell me your country (or the exact brand name(s) you saw on the box), I can map them to the generic metformin and identify whether it’s immediate-release or extended-release.
