What is Metformin?

Metformin is a medication which is licensed to treat diabetes and polycystic ovary systems. 

Metformin may be prescribed to diabetics to help them control blood sugar levels. Metformin can help the body use insulin better thereby helping with diabetes management.

Metformin is prescribed as a first line treatment for people with Type 2 diabetes. It may be combined with other medication depending on the patient’s needs.  

Diabetics have problems with the function of insulin in the body. Diabetics either struggle to make enough, or properly use insulin. Insulin is the hormone involved in controlling your blood glucose levels. 

Metformin improves insulin sensitivity, this means it works by helping your body use insulin better which can help with diabetes management.

Metformin is sold and a generic medication, or under brand names such as Glucophage.
