Metformin
Metformin is a diabetes drug that lowers blood glucose (or blood sugar levels) by decreasing the amount of glucose your liver releases into the blood stream. It also increases the sensitivity of your body's cells to insulin, so more glucose is taken into cells with the same amount of insulin in the blood stream. Metformin is generally the first medicine prescribed for diabetes, if your blood glucose level is not controlled by changes in lifestyle. It is a useful treatment if you are overweight, as weight gain as a side-effect is less common.
