Can Glucophage interact with other medications or foods?

Glucophage (metformin) may interact with other medications, so it is important to tell your doctor about any medications or supplements you are taking before you take Glucophage. This is especially true if you are taking any of the following medications:
  • beta-blockers
  • calcium channel blockers
  • thyroid medications
  • birth control pills
  • corticosteroids
  • sulfonylureas
  • sympathomimetics
  • diuretics
  • insulin
  • amiloride
  • cimetidine
  • phenytoin
  • isoniazid
  • vancomycin
  • quinidine
  • ranitidine
  • nicotinic acid
  • triamterene
  • morphine
  • digoxin
  • trimethoprim
  • quinine
  • procainamide
Drinking alcohol while taking Glucophage may also increase the risk for serious side effects. Other medications and substances may also interact with Glucophage, so do not stop, start, or change any medications or supplements without first talking to your doctor.
