Takes metformin everyday. Gets leg cramps, started taking quinidine. Saw in previous notes that there may be risks, what kind of results such we look for?
Yes, a theoretical drug interaction exists. The addition of quinidine could result in higher blood levels of Metformin than before. This could lead to symptoms of lactic acidosis (nausea and weakness) because lactic acid builds up in your blood stream.
If you are prescribed quinidine your metformin dose may need to be reduced and your blood glucose measured carefully. You should report any unusual symptoms to your doctor.
