Davocet & Darvon Pulled From Market After Study Correlates Use With Deadly Heart Problems


On November 19, 2010 the FDA ordered the popular painkillers Darvocet & Darvon to be pulled from the market.

The decision to pull Darvocet & Darvon came after exhaustive studies and feedback from panels assembled by the FDA to evaluate the drugs safety. The results followed careful evaluation of advisory panel findings and data from scientific studies that concluded that the drugs should be pulled from the market because of the strong correlation to QT internal abnormalities in the heart.

Specifically, electrocardiography data demonstrated that even healthy patients developed abnormal heart rhythms after using Darvocet and Darvon (propoxyphene) as intended with the dosages recommended by the manufacturer.

Though these drugs were approved for treatment of pain more than 50 years ago, there has been widespread requests to have the drugs removed from the market as more painkillers have become available that have minimal side-effects.

The legal rights of for those who were injured or killed

Given the extensive history of use of Darvocet and Darvon, it is extremely likely that the manufacturer Xanodyne Pharmaceuticals, Inc. had knowledge of the dangers of the heart problems associated with these drugs– yet never warned the public or took action to remove them from the market prior to this recent FDA action.

If you have a loved one who suffered an injury or death following the use of Darvocet or Darvon, you may have legal rights for damages against the drug manufacturer.  Currently, we are evaluating cases involving the following complications:

  • Irregular heart rhythms
  • Bradycardia
  • Stroke
  • Techycardia
  • Heart attack
  • Heart failure
  • Blockage in the heart
  • Death

Though Darvocet and Darvon lawsuits are in the early stages, you may wish to talk with a drug lawyer to discuss your potential legal rights.

As always, we offer you the opportunity to speak to a lawyer for a free evaluation of your circumstance. (800) 926-7565

  1. Dr Ulf Jonasson says:

    Dear Sirs,
    We want to add to this text that we have studied the painkilling substance propoxyphene (DXP) since 1993. Now FDA says that ONE NEW STUDY made them stop Darvon. We have informed FDA about our research since 1999-2000, they know about our 9-10 scientific articles about the substance, we also wrote two doctorial dissertations (2000 and 2001) in Sweden.
    We are actually the Whistleblowers about the painkilling substance Propoxyphene in the whole world and informed Public Citizen in 2002 and 2003. I personally met with Dr Larry Sasich at Public Citizen in Washington DC and informed the about our research.
    Our research was behind the decision in UK, Sweden and The European Union (EU) to stop the drug. Go to this link, http://qjmed.oxfordjournals.org/content/98/3/159.2.full

Justia Lawyer Rating for Jonathan Rosenfeld

Client Reviews

Jonathan did a great job helping my family navigate through a lengthy lawsuit involving my grandmother's death in a nursing home. Through every step of the case, Jonathan kept my family informed of the progression of the case. Although our case eventually settled at a mediation, I really was impressed at how well prepared Jonathan was to take the case to trial. Lisa
After I read Jonathan’s Nursing Home Blog, I decided to hire him to look into my wife’s treatment at a local nursing home. Jonathan did a great job explaining the process and the laws that apply to nursing homes. I immediately felt at ease and was glad to have him on my side. Though the lawsuit process was at times frustrating, Jonathan reassured me, particularly at my deposition. I really felt like Jonathan cared about my wife’s best interests, and I think that came across to the lawyers for the nursing home. Eric
