(SILVER SPRING, Md.) -- The painkiller known by the brand names Darvon and Darvocet has been on the market since the 1950s, but now, it is being pulled from the market. Under pressure from critics who say hundreds die every year from heart problems caused by the drug, manufacturer Xanodyne has agreed to withdraw it from U.S. markets.
The Food and Drug Administration says the new concerns about Darvon and Darvocet follow new clinical data linking the drugs -- both technically known as propoxyphene -- to potentially fatal heart rhythm abnormalities. The agency says the clinical data, combined with new epidemiological research and other information, mean the risks now outweigh the benefits of Darvon and Darvocet.
Doctors are being advised to stop prescribing the medication. People who are taking it are advised to contact their doctors immediately.
