Dear Healthcare Professional,

The manufacturers of gadolinium-based contrast agents would like to inform you of important revisions to the prescribing information for the products listed in alphabetical order above. Gadolinium-based contrast agents are approved by the U.S. Food and Drug Administration (FDA) for use in magnetic resonance imaging (MRI).

Post-marketing reports show that the use of these agents increases the risk of the development of a serious medical condition called Nephrogenic Systemic Fibrosis (NSF), in patients with acute or chronic severe renal insufficiency (glomerular filtration rate <30mL/min/1.73m2) and patients with renal dysfunction due to the hepatorenal syndrome or in the perioperative liver transplantation period.

NSF leads to excessive formation of connective tissue in the skin and internal organs. NSF is progressive and may be debilitating or fatal. As of today, the FDA has received reports of over 250 cases of NSF after administration of gadolinium-based contrast agents.

As a result of these NSF cases, the package inserts of all gadolinium-based contrast agents have been revised to include the following Boxed Warning and update to the WARNINGS section.
