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. Read the Patient Information Leaflet if available from your pharmacist before you start taking metformin and each time you get a refill. buy cialis lowest price Metformin is a biguanide used to treat type 2 diabetes mellitus and most commonly prescribed oral hypoglycemic agent. Metformin is now also used to treat polycystic ovary syndrome and some malignancies. Despite a good safety profile in a majority of patients with diabetes, the risk of metformin-associated lactic acidosis is genuine when safety guidelines are ignored. Overdoses with metformin are rare, but may result in serious consequences. Case reports and small case series of serious toxicity from metformin overdosage can be found in the medical literature, often with the portrayal of extracorporeal methods for the management of the subsequent severe lactic acidosis. Lactic acidosis can defined as a metabolic acidosis with a blood p H less than 7.35 and a serum lactate more than 2 mmol per liter. It can occur either with therapeutic metformin dosing (which is rare) or in overdose situations. Cialis review forum Effects of a metformin overdose will vary depending on a number of factors, including how much metformin was taken and whether it was taken with any other medicines, alcohol, and/or drugs.

Acute metformin overdose: Examining serum p H lactate Levels and metformin concentrations in survivors versus nonsurvivors: A systematic review of the literature. Annals of Emerg Med 2009; 54: 818-23 Metformin, a blood-glucose-lowering drug widely used for treatment of type 2 diabetes, is associated with risk of potentially fatal metabolic (lactic) acidosis. This can occur not only following overdose but also at therapeutic dose in patients with pre-existing renal or liver disease. Results of arterial blood gas analysis reflect metabolic acidosis (reduced blood p H, reduced bicarbonate compensatory increase in ) and increased plasma lactate. Is it possible, as might be intuitively expected, to predict survival in such cases from the severity of the acidosis and/or severity of the hyperlactatemia? Investigators conducted a systematic review of the literature and identified 22 well-documented case histories of metformin overdose, five of which had a fatal outcome. For each of these cases, investigators abstracted lowest (nadir) p H, highest (peak) plasma lactate concentration and highest (peak) plasma metformin concentration. The median nadir p H among non-survivors was 6.71 (interquartile IQ range 6.71-6.73), this compared with median p H 7.30 (IQ range 7.22-7.36) for survivors.
