Metformin is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to help improve blood glucose control, along with diet and exercise, in adults with type 2 diabetes. Metformin is sometimes prescribed off-label to treat hidradenitis suppurativa (HS). Metformin is sold under brand names including Fortamet, Glucophage, Glumetza, and Riomet.
Metformin is a member of a drug class called biguanides. In cases of type 2 diabetes, metformin is believed to work by decreasing the amount of glucose produced by the liver and making the muscle tissue more sensitive to insulin. In cases of HS, metformin may help by influencing levels of insulin and other hormones and by promoting weight loss.
