Phenformin and lactic acidosis
Abstract
Thirty-eight patients who presented with diabetes and a changed state of consciousness satisfied the criteria for lactic acidosis. Sixteen patients were non-ketotic, and 15 of these were receiving phenformin on admission. In all but one of these 15 patients, however, additional renal or cardiovascular abnormalities, or both, could be identified, which supported a multifactorial aetiology for lactic acidosis. Advanced age and cardiovascular and renal disease are absolute contraindications to the use of phenformin in diabetics.
