Glucophage 1000 mg (Merck) contains metformin. It works mainly by helping lower the amount of glucose (sugar) in your blood.

How it works

• Liver: reduces the amount of glucose the liver releases into the bloodstream.
• Muscles and other tissues: helps the body respond better to insulin, so glucose can move from the blood into cells more effectively.
• Intestines: it may also slightly reduce the absorption of glucose from food.
