What Is Metformin ER 750mg?
Metformin ER is an extended-release form of metformin, a biguanide medication that helps lower blood sugar in adults with type 2 diabetes. It works by reducing the amount of glucose your liver produces, decreasing glucose absorption in the intestines, and improving your body's sensitivity to insulin. The extended-release tablet dissolves slowly, allowing once-daily dosing and often causing fewer stomach-related side effects than immediate-release metformin. It is used together with diet and exercise, and may be taken alone or with other diabetes medications.
