FDA Recommends Against the Continued Use of Propoxyphene (Darvon, Darvocet, and Others)

On November 19, 2010, the U.S. Food and Drug Administration (FDA) announced that it intends to withdraw the pain medicine propoxyphene from the United States market, because this drug may cause serious toxicity to the heart. The FDA is basing this decision on new study information that shows propoxyphene can cause significant changes to the electrical activity of the heart, even when the drug is used at therapeutic doses. These changes, which can be seen on an electrocardiogram (ECG), can increase the risk for serious abnormal heart rhythms.

At this time, Xanodyne Pharmaceuticals Inc., which makes Darvon and Darvocet, the brand version of propoxyphene, has agreed to withdraw the medication from the U.S. market. The FDA has notified the generic manufacturers and requested that they voluntarily remove their propoxyphene products as well.

Propoxyphene is an opioid pain reliever used to treat mild to moderate pain. It is sold under various names as a single-ingredient product (Darvon) and as part of a combination product with acetaminophen (Darvocet). Propoxyphene is also known by such names as Dolene, Propacet 100, Wygesic, Trycet, Genagesic, E-Lor, and Balacet.

To answer some of the questions and concerns about this decision, the FDA has published a web page titled "Questions and Answers: FDA recommends against the continued use of propoxyphene." To view the FDA's Question and Answer web page, please visit: more information here
