Metformin is used to help lower blood sugar levels in people with type 2 diabetes.

Metformin works in a few different ways to help keep your blood glucose (sugar) from getting too high.

Metformin decreases the amount of glucose your body absorbs from things you eat and drink.
Metformin reduces the amount of glucose that your liver makes.
Metformin also helps your body’s own insulin to work better. (Insulin is a hormone that helps your body use glucose as a source of energy.)
