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.

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.

Metformin is sometimes used together with insulin or other medications, but it is not for treating type 1 diabetes. You should not use metformin if you have severe kidney disease, metabolic acidosis, or diabetic ketoacidosis (call your doctor for treatment). If you need to have any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking metformin. Though extremely rare, you may develop lactic acidosis, a dangerous build-up of lactic acid in your blood.
