BackgroundBiguanides pose a significant risk of morbidity, mortality and permanent sequelae secondary to prolonged periods of hypoglycaemia.ObjectivesTo investigate the treatment of massive metformin overdose associated with lactic acidosis.Case ReportWe present the case of a 30-year-old woman, who attempted to commit suicide by ingesting an 85-g massive metformin overdose associated with severe lactic acidosis, which we treated by performing prolonged haemodialysis with bicarbonate and plasma exchange.ConclusionFor the maximum elimination of metformin, extended haemodialysis is required and the treatment of the accompanying metabolic acidosis with bicarbonate is important for the effectiveness of the treatment. Patients benefit much more from the treatment of combined haemodialysis with plasma exchange.
