The Food and Drug Administration said Wednesday it is asking manufacturers of certain contrast agents used in patients undergoing magnetic resonance imaging, or MRI scans, to place a black-box warning on the agents' packaging.
The FDA said the warning, which would apply to five gadolinium-based contrast agents, including ones made by General Electric Co.'s health-care unit and a unit of Bayer AG, would state that patients with severe kidney insufficiency are at risk for developing a debilitating, and a potentially fatal, disease known as nephrogenic systemic fibrosis, or NSF. |
