I read the precautions for GLUCOPHAGE and it mentioned something about lactic acidosis. Specifically it says:


"Metformin can rarely cause a condition called lactic acidosis,which can be fatal. Seek immediate medical attention if you develop any of the following symptoms of lactic acidosis: unusual tiredness (fatigue) or severe drowsiness, muscle pain, breathing trouble or rapid breathing, unusually slow or irregular heartbeat. Lactic acidosis is more likely to occur in patients who: have heart failure, kidney or liver problems; are elderly; use alcohol excessively; are seriously dehydrated (lack body fluids); will undergo x-ray procedures that require an injectable contrast drug; will have surgery ; develop a serious infection, heart attack or stroke; are over 80 years of age and have not had kidney and liver tests."

I found this kind of vague. What is it that METFORMIN does that causes LACTIC ACIDOSIS and how is it fatal?
