Metformin is sold under a number of different brand names. As a diabetes treatment, Metformin has been marketed extensively.

This page details some Metformin brands, all of which fall under the non-sulfonylureas class of diabetes drugs.

The most common Metformin brand name is Glucophage, but there are many other less common Metformin brands.

To make it easier for people with diabetes to understand the different brands of Metformin, we have profiled some of the most common ones below.

Actoplus Met

Actoplus Met is a combination of two oral diabetes medications (pioglitazone HCl and metformin HCl).

This treatment is designed for people with type 2 diabetes. ACTOplus met includes an extended-release form of Metformin, alongside diabetes drug Actos (pioglitazone).

This brand of metformin is designed to improve glyceamic control simply and conveniently.

Whilst Metformin reduces the amount of glucose producted in the liver, Actos directly targets insulin resistance


Apo-Metformin is another brand of Metformin that comes under the medication calls of oral hypoglycaemics.

Like other Metformin brands, Apo-Metformin functions to reduce the amount of glucose made by the liver.

FORTAMET Extended-Release Tablets

FORTAMET is a once-daily 1000 mg extended-release metformin tablet for people with type 2 diabetes.

FORTAMET is for use by adults aged 17 years or older, and can be used either as a monotherapy or as a combination therapy.

Like all Metformin, Fortamet should be used alongside diet and exercise to lower blood sugar levels and maintain control.


Riomet (also called metformin hydrochloride oral solution) is a unique brand of metformin. It is the first and only type of liquid metformin available. Like all metformin, Riomet is used in conjunction with diet and exercise to lower blood glucose levels amongst people with type 2 diabetes. 5mL is the equivalent of 500mg tablets of metformin.


Glumetza is another form of metformin. Like most metformin, glumetza is contraindicated amongst patients with diabetic ketoacidosis, metabolic acidosis and renal dysfunction. Glumetza is an extended release tablet used as an oral antihyperglycaemic drug.


Obimet is often the first choice of metformin brands for people with diabetes and obesity. Obimet lowers hypoglycaemia risks and comes in blister packs of ten tablets, usually either 500mg or 1000mg. Obimet is sometimes prescribed as an initial therapy, or may be delivered alongside a sulphonylurea.


Like all of the metformin brands, the active ingredient of dianben is metformin hydrochloride. Dianben comes in 850mg tablets that are classed as oral anti-diabetics.

This drug is usually prescribed to overweight patients who cannot achieve adequate control using diet and exercise Dianben 850mg is either used as a monotherapy or in conjunction with other drugs or insulin.


Diabex is prescribed to people with diabetes aged 10 years or older to improve blood sugar levels.

Diabex, unlike some other metformin brands, is also used to treat anovulatory infertility caused by polycystic ovary syndrome.

Diabex is prescribed in 500mg or 1000 mg extended release formulations.
