The FDA announced in November 2010 that the Darvon, Darvocet, and their generic medication wree being withdrawn from the U.S. market. The painkillers were linked to serious heart risks that could result in sudden death.
The FDA received reports of the problems as early as 1978. Consumer groups began calling for the ban of the drug in 2006. The drugs were withdrawn in Europe in June 2009, but stayed on the market here. Finally the FDA removed the drug this past November.




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 8 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 i Washington DC and informed them 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,
