Proper control of diabetes may also lessen your risk of a heart attack or stroke. This medication is also used in people with type 2 diabetes and heart disease to lower the risk of going to the hospital for heart failure.

It also increases the removal of sugar by your kidneys, decreases how much sugar is made in your liver, and decreases how much sugar your body takes in through your stomach and intestines.Taken as directed by physician
