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.
As a centrally acting narcotic pain reliever, Darvon works in the central nervous system (the brain and spinal cord), rather than directly at the site of the pain. The effects of Darvon are not considered as "strong" as those of most other narcotic pain relievers. Because it is a weaker painkiller and can be potentially lethal in the case of an overdose, Darvon is not usually a "first choice" pain medication in most situations.
Darvon's effects can also cause psychological and physical dependence. This medication is a narcotic drug and is classified as a
controlled substance. Although there are strict rules and regulations regarding its sale and use, this is a commonly abused drug.
