Renal Insufficiency and Metformin

Because of concerns of lactic acidosis (and subsequent high risk of mortality), metformin should not be used in patients with renal failure or severe renal insufficiency. When I get lab results back showing an elevated creatine, I have made it a habit to check 1) what the last creatine was, and 2) if the patient is currently taking metformin.
