Interactions: Cationic drugs eliminated by renal tubular secretion (eg, amiloride, digoxin, morphine, procainamide, quinidine, quinine, ranitidine, triamterene, trimethoprim, vancomycin); may increase metformin levels; monitor. Increased risk of lactic acidosis with topiramate, other carbonic anhydrase inhibitors (eg, zonisamide, acetazolamide, dichlorphenamide). Diuretics, steroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, sympathomimetics, nicotinic acid, CCBs, and isoniazid may cause hyperglycemia.

Avoid excessive alcohol. Concomitant drugs that may affect renal function or metformin disposition; monitor and adjust dose. Antagonized by UGT inducers (eg, rifampin, phenytoin, phenobarbital, ritonavir): see Adults. Concomitant digoxin: monitor. Concomitant insulin or insulin secretagogue: consider a lower dose of insulin/insulin secretagogue to reduce risk of hypoglycemia. May cause false (+) urine glucose tests or unreliable measurements of 1, 5-AG assay; use alternative methods to monitor glycemic control.
