Metformin other names?

What other names does metformin go by?

Metformin’s generic name is often shortened or written with different spellings across countries and labels. Common “other names” you’ll see include:
- Metformin
- Metformin hydrochloride (metformin HCl)
- Metformin ER (extended-release) or XR (extended-release form)

Brand names and what to look for on a prescription

Metformin is marketed under multiple brand names that can vary by country. If you tell me your country (or share the exact label text), I can narrow it to the specific brand(s) used where you live.

How to identify metformin vs. similar drugs

If you’re checking a label, “metformin” is the key active ingredient. Other diabetes medicines will have different generic names (for example, “glimepiride” or “pioglitazone”), even if they’re used for similar conditions.

If you mean “metformin” in a specific medication form

Metformin also appears in different formulations that may affect the name you see:
- Immediate-release tablets (often just “metformin”)
- Extended-release tablets (often written as “metformin ER” or “metformin XR”)

Can metformin be combined with other medicines?

Yes. Some products combine metformin with another diabetes drug, so the name may look like “metformin + [other generic]” on the package (for example, a combination tablet). The exact combination depends on the country and product.
