In March 2007, Zelnorm was taken off the market in the United States because it was shown to increase the risk for a heart attack, angina, or stroke. In July 2007, the United States Food and Drug Administration (FDA) announced that Zelnorm will be available to people who meet certain criteria through a special program called a "treatment IND" (see Zelnorm Recall for more information). However, as of April 2, 2008, Zelnorm is no longer available under the treatment IND program, although it may still be available in certain emergency situations.
