Bayer AG has begun the process of settling medical injury lawsuits regarding its Magnevist contrast agent; Magnevist contains gadolinium.
The company is one among several, including General Electric Company and Tyco International Limited, being sued over complaints that the gadolinium-containing contrast agent was responsible for causing a potentially fatal organ hardening disease, called Nephrogenic Systemic Fibrosis (NSF). Since May 2007, the U.S. Food and Drug Administration (FDA) has required that gadolinium-containing contrast agents carry a black box warning.
