Metformin (Glucophage) for polycystic ovary syndrome
You may need to stop taking metformin temporarily before major surgery or other medical procedures, such as X-rays that use contrast dyes. Talk to your doctor about this before your surgery or procedure.
The effect of metformin may be increased if you also take cimetidine (Tagamet). Before taking metformin, talk with your doctor about any other medicines you are taking.
