Xanodyne Pharmaceuticals Inc. – the maker of Darvon and Darvocet, the brand version of the prescription pain medication propoxyphene – has agreed to withdraw the medication from the U.S. market at the request of the U.S. Food and Drug Administration, the FDA said on Friday.
The FDA sought the action after new clinical data showed the drug puts patients at risk of potentially serious or even fatal heart rhythm abnormalities.
