An overdose of metformin may cause lactic acidosis. Get emergency medical help if you have any of these symptoms of lactic acidosis: weakness, increasing sleepiness, slow heart rate, cold feeling, muscle pain, shortness of breath, stomach pain, feeling light-headed, and fainting.
What should I avoid while taking metformin (Riomet)?

- trimethoprim (Proloprim, Primsol, Bactrim, Cotrim, Septra); or

You may be more likely to have hyperglycemia (high blood sugar) if you take metformin with other drugs that can raise blood sugar, such as:
- diuretics (water pills);
- steroids (prednisone and others);
- heart or blood pressure medication (Cartia, Cardizem, Covera, Isoptin, Verelan, and others);

- thyroid medicine (Synthroid and others);
