Metformin is a commonly used treatment modality in type 2 diabetes mellitus, with a well documented side effect of lactic acidosis. In the intensive care setting lactate and p H levels are regularly used as a useful predictor of poor prognosis. In this article we highlight how high lactate levels are not an accurate predictor of mortality in deliberate metformin overdose.

These figures would normally correspond with a mortality of more than 80%; however, with appropriate management this patient’s condition improved. We provide evidence that the decision to treat severe lactic acidosis in deliberate metformin overdose should not be based on arterial lactate and p H levels, as would be the case in other overdoses. buy xenical new zealand Rarely, too much metformin can build up in the body and cause a serious (sometimes fatal) condition called lactic acidosis.
