Sammanfattning
Metformin is eliminated through glomerular filtration and tubular secretion in the kidneys. New guidelines recommend use of metformin down to a GFR of 30 mL/min under the condition that the dose is adjusted. As the risk of inducing lactic acidosis is very low in connection with administration of iodine contrast media, new recommendations in Sweden say that metformin must be stopped only when GFR is below 45 mL/min. Determination of metformin levels in serum is useful to guide therapeutic dose when GFR is low but also to confirm that lactic acidosis is caused by metformin.
