Health Research Group Petitions to Phase Out the Sale of the Painkiller Propoxyphene (DARVON, DARVOCET, and Generic Versions)
June 2006
On Feb. 28, 2006, the Health Research Group petitioned the Food and Drug Administration (FDA) to immediately begin phasing out the sale of the dangerous painkiller propoxyphene (DARVON). The reason for the petition is that propoxyphene has been associated with over 10,000 confirmed deaths and 2,110 reported accidental deaths in the U.S. from 1981 through 1999. There are many generic versions of propoxyphene on the market, as well as a number of products that combine propoxyphene with acetaminophen (TYLENOL). These products are sold as DARVOCET and are also widely sold as generic drugs. A phased withdrawal, instead of an immediate ban, is necessary because of the addicting properties of the drug and the need to switch patients to other painkillers.
