Darvon and Darvocet Drug Litigation - Kline and Specter

The painkillers Darvon and Darvocet have been removed from the market because they can cause serious and potentially fatal heart rhythm abnormalities.

The U.S. Food and Drug Administration advised on Nov. 19, 2010 that doctors immediately stop prescribing the drug, generically propoxyphene, and that patients discard any existing Darvon and Darvocet and switch to another pain medication.

An FDA panel of experts voted last year to recommend the removal of Darvon and Darvocet. The drugs have been banned in Great Britain since 2005 and were withdrawn in the European Union in 2009 based partly on reports of excess deaths among patients who used the painkillers.

The FDA reported recently that a new study showed use of Darvon at therapeutic doses caused significant changes to electrical activity of the heart. Prior evidence from medical examiners in Florida also reportedly showed increased deaths among users of the painkillers.

The drugs, manufactured by Xanodyne Pharmaceuticals Inc. and on the market since 1957, have been very popular, especially among older people, with roughly 120 million prescriptions filled in the United States since 2005. Sales have decreased in more recent years with the advent of newer pain medicines, but some 10 million prescriptions for Darvon and Darvocet  were still filled in 2009.

Kline & Specter, PC, has a record of success in litigating pharmaceutical and product liability cases. However, we are no longer accepting cases involving side effects of Darvon and Darvocet.
