AUDIENCE: Radiology, Nephrology, Dermatology
ISSUE: FDA is requiring changes in the professional labeling for gadolinium-based contrast agents (GBCAs) to minimize the risk of nephrogenic systemic fibrosis (NSF), a rare, but serious, condition associated with the use of GBCAs in certain patients with kidney dysfunction. NSF has not been reported in patients with normal kidney function. Patients at greatest risk for developing NSF after receiving GBCAs are those with impaired elimination of the drug, including patients with acute kidney injury or chronic, severe kidney disease.
BACKGROUND: GBCAs are intravenous drugs used in diagnostic imaging procedures to enhance the quality of magnetic resonance imaging or magnetic resonance angiography.
RECOMMENDATION: Healthcare professionals should screen patients prior to administration of a GBCA to identify those with acute kidney injury or chronic, severe, kidney disease. See the Drug Safety Communication for the complete list of recommendations to healthcare professionals and patients.
