Metformin is an oral drug which lowers blood sugar levels by decreasing the amount of sugar produced in the liver and increasing the sensitivity of muscle cells to insulin. However, metformin use had been thought in the past to predispose patients with Type 2 diabetes, especially those with underlying kidney problems, to increased risk of kidney failure or serious cases of lactic acidosis. Because of this potential risk, the ACR and the Food and Drug Administration (FDA) issued strict guidelines in 2013 about the use of metformin when contrast is used in medical imaging. These guidelines came about because such contrast can damage the kidneys in some cases, a condition called contrast-induced nephropathy. The 2013 guidelines recommended that metformin be stopped 48 hours post-procedure, and that it should not be taken again until doctors see the kidney is not injured. In 2015, these restrictions were removed from the guidelines, according to a article. This is partly because most radiologists simply weren’t following the 2013 guidelines, and partly because the rate of contrast-induced nephropathy in metformin users has been found to be incredibly low.
