Where this comes from

Abstract

Convention holds that the use of metformin is contraindicated in many patients secondary to concerns about lactic acidosis. However, current evidence suggests that metformin-associated lactic acidosis is at most idiosyncratic. Awareness of the current evidence should permit broader use of this valuable medication.
