Glucophage is a brand name for a medication that contains the active ingredient metformin. Metformin is an oral medication commonly used to manage and control high blood sugar levels in people with type 2 diabetes. It is part of a class of drugs called biguanides.

Metformin works by decreasing the amount of sugar produced by the liver and increasing the sensitivity of muscle cells to insulin, which helps the body use blood sugar more effectively. This can help lower and stabilize blood glucose levels in individuals with type 2 diabetes.
