Metformin belongs to the class of medications called oral hypoglycemics, which are medications that lower blood sugar. It is used to control blood glucose (blood sugar) for people with type 2 diabetes. It is used when diet, exercise, and weight reduction have not been found to lower blood glucose well enough on their own.
Metformin works by reducing the amount of glucose made by the liver and by making it easier for glucose to enter into the tissues of the body. Metformin has been found to be especially useful in delaying problems associated with diabetes for overweight people with diabetes.
