Please note: The information on this page is provided for informational purposes only. As of 2011, Simmons Hanly Conroy is no longer accepting cases involving Darvocet.

Darvon and Darvocet are the brand versions of the prescription pain medication propoxyphene. The medication was previously used to treat mild pain because of its local anesthetic effects on the body. The manufacturer of the drug is Xanodyne Pharmaceuticals Inc.

When clinical data found the drug puts patients at an increased risk for serious, life-threatening heart rhythm abnormalities, the FDA sought market withdrawal. Studies revealed that even when taken at recommended doses, propoxyphene causes significant alterations to the heart’s electrical activity. These changes are visible on an electrocardiogram (ECG) and can increase the risk for serious abnormal heart rhythms linked to dangerous adverse effects, including sudden death.

The manufacturer of Darvon and Darvocet has recalled the medications from the U.S. market at the request of the U.S. Food and Drug Administration.
