Metformin HCl 500 mg is a commonly prescribed medication for controlling Type 2 Diabetes. It works by reducing the amount of glucose produced by the liver and improving the body's sensitivity to insulin, which helps lower blood sugar levels. Unlike some other diabetes medications, Metformin does not increase insulin production, thus reducing the risk of low blood sugar (hypoglycemia). It is typically taken with meals to minimize gastrointestinal side effects. Metformin is often the first-line treatment for Type 2 Diabetes and may be used in combination with other medications or insulin for better blood sugar control.
