Darvocet – sold under that name as well as the brand name Darvon and the generic propoxyphene – was voluntarily removed from the United States marketplace in late November of 2010. Darvocet – a well-known prescription pain medication manufactured by Xanodyne Pharmaceuticals, Inc. – has been around for more than 50 years. During that time, it has been prescribed to tens of millions of patients suffering from acute or chronic pain.Consumer watchdog groups like Public Citizen applaud the federal Food and Drug Administration (FDA)’s finally recommending that Darvocet be taken off the market. They fear, however, that the action may have come too late. Public Citizen and similar organizations have been promoting awareness of the drug’s toxic effects on the body since 1978, but the FDA refused to take action. Studies around the world have shown detrimental effects of the drug that far outweigh its benefits. Those same studies led regulators in the United Kingdom to take the medication off the market in 2005; the European Union followed suit in 2009.The FDA has been investigating complaints of heart-related damage linked to propoxyphene medications like Darvocet for years, but insisted on running their own research study before they would recommend a withdrawal. Not surprisingly, the FDA’s study proved that the drug causes a significantly increased risk of heart damage, heart arrhythmia and sudden death even when taken as prescribed.Since Darvocet and other propoxyphene medicines were on the market for over half a century, potentially thousands of injuries or deaths can be linked to their use. If you or a loved one took a propoxyphene medicine like Darvocet or Darvon and suffered heart damage, seek the advice of a skilled defective products attorney in your area to learn more about your legal rights, responsibilities and options.
