About pioglitazone

Pioglitazone is a medicine used to treat type 2 diabetes.

Type 2 diabetes is a condition where the body does not make enough insulin, or the insulin that it makes does not work properly. This can cause high blood sugar levels (hyperglycaemia).

Pioglitazone helps to control your blood sugar levels by helping your body make better use of the insulin it produces.

Pioglitazone is only available on prescription. It comes as tablets.

It also comes as tablets containing a mixture of pioglitazone and another diabetes medicine called metformin. This is known by the brand name Competact.
