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. We present the case of a 70-year-old Caucasian man who took a deliberate metformin overdose of unknown quantity. He had a profound lactic acidosis at presentation with a p H of 6.93 and a lactate level of more than 20mmol/L. 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. cipro gram Rarely, too much metformin can build up in the body and cause a serious (sometimes fatal) condition called lactic acidosis. Lactic acidosis is more likely if you are an older adult, if you have kidney or liver disease, dehydration, heart failure, heavy alcohol use, if you have surgery, if you have X-ray or scanning procedures that use iodinated contrast, or if you are using certain drugs. For some conditions, your doctor may tell you to stop taking this medication for a short time. Stop taking this medication and get medical help right away if you have any symptoms of lactic acidosis, such as unusual tiredness, dizziness, severe drowsiness, chills, blue/cold skin, muscle pain, fast/difficult breathing, slow/irregular heartbeat, or stomach pain with nausea/vomiting/diarrhea. Show More Metformin is used with a proper diet and exercise program and possibly with other medications to control high blood sugar. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Metformin works by helping to restore your body's proper response to the insulin you naturally produce. It also decreases the amount of sugar that your liver makes and that your stomach/intestines absorb.

Your doctor should advise you to stop taking it before you have any medical exams or diagnostic tests that might cause less urine output than usual. You may be advised to start taking the medicine again 48 hours after the exams or tests if your kidney function is tested and found to be normal. Make sure any doctor or dentist who treats you knows that you are using this medicine. You may need to stop using this medicine several days before having surgery or medical tests. The highest postmortem metformin concentrations are recorded utilizing a sensitive and specific analytical procedure. The peripheral blood metformin concentration was 240 mg/L, the liver concentration was 240 mg/kg and the gastric concentration was 1,700 mg. Additionally, an antemortem blood sample collected shortly after admission revealed a metformin concentration of 210 mg/L. These data, revealing a liver to peripheral blood ratio of 1.0, provide additional support that metformin is not subject to postmortem redistribution. Intentional self-poisonings with metformin can result in death, despite multiple medical interventions. Since being approved by the United States Food and Drug Administration in 1995, metformin, a member of the biguanide class of oral hypoglycemics, has become one of the most popular medications prescribed in the United States (1). Because of its widespread use, it is not surprising that over 7,500 cases of metformin exposures were reported to United States poison control centers in 2010 (2).
