In November 2010, the United States Food and Drug Administration (FDA) withdrew all medications that contain propoxyphene from the market. It has been determined that the risks of propoxyphene outweigh the possible benefits. In particular, the FDA was concerned about the drug's ability to cause serious changes in the heart rhythm, even at normal doses. Pharmacies will no longer sell this medication, and people who take it should stop and ask their healthcare provider for a more suitable pain medication.
Who Makes This Medication?
Brand-name Darvon is made by Xanodyne Pharmaceuticals, Inc. Generic versions are made by various manufacturers.
Darvon is classified as a centrally acting narcotic pain reliever. "Centrally acting" means that it works in the central nervous system (the brain and spinal cord), rather than directly at the site of the pain. Darvon is not considered as "strong" as most other narcotic pain relievers and is particularly dangerous in the case of overdoses. As a result, Darvon is not usually a "first-choice" pain medication in most situations.
