Missouri Darvon and Darvocet Lawyers

Have You Or Someone You Love Been Injured By Darvon® Or Darvocet®?
The Roberts Law Firm, P.C. Can Help


Darvon® and Darvocet® marketed by Xanodyne Pharmaceuticals, Inc. is the chemical compound propoxyphene, an opioid pain reliever used to treat mild to moderate pain. Darvon is the brand name for propoxyphene and Darvocet is the brand name for propoxyphene mixed with acetaminophen. These pain killers were approved by the FDA in 1957, but have been plagued by safety concerns ever since. The FDA estimates that 10 million prescriptions of Darvon® and Darvocet® were written in the United States in 2009 and that 17.5 million prescriptions of the generic version were written in 2009.


Healthcare professionals were notified on November 19, 2010 that Xanodyne Pharmaceuticals, Inc. agreed to withdraw propoxyphene from the U.S. market at the request of the FDA, due to new data showing that the drug can cause serious toxicity to the heart, even when used at therapeutic doses. FDA concluded that the safety risks of propoxyphene outweigh its benefits for pain relief at recommended doses. FDA requested that the generic manufacturers of propoxyphene-containing products remove their products as well.


In addition to the increased risk of heart arrhythmias, the drug has been linked to increased risk of suicide and accidental overdoses. Some experts estimate that this dangerous drug may also be responsible for a death rate of 16 deaths for every 100,000 prescriptions. According to a statement issued by Dr. Sidney Wolfe of Public Citizen “Evidence going back more than 30 years indicates that propoxyphene is not very effective, is toxic at doses not much higher than the recommend dose,” and is “somewhat addictive”. The New York Times reported that “Propoxyphene has been shown to have very little effect on pain. Many studies showed no significant improvement by adding it to acetaminophen. Propoxyphene also has a narrow margin of safety between the recommended dose and a harmful dose or fatal overdose, according to the F.D.A. review and other experts.”


The FDA announcement of Darvon and Darvocet’s withdrawal from the market says the drug “puts patients at risk of potentially serious or even fatal heart rhythm abnormalities.” Darvon and Darvocet can interfere with the electrical functioning of the heart, causing:

  • Cardiac toxicity
  • Arrhythmia
  • Fibrillation
  • Irregular and erratic heartbeats
  • Sudden, fatal cardiac arrest
  • Sudden, fatal heart attacks

The drug is also unusually prone to cause overdoses. Darvon, Darvocet and the generic forms of propoxyphene have all left a history of fatalities behind them.
