How They Interact
Cimetidine interferes with the body's ability to get rid of metformin through the kidneys, which can cause the drug to build up to unsafe levels.
FDA Label Information
Drugs that Reduce Metformin Clearance Clinical Impact: The risk of lactic acidosis may increase due to concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) which increase systemic exposure to metformin Intervention Consider the benefits and risks of concomitant use.
