Effects of Darvocet

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.
Darvocet® (propoxyphene/acetaminophen) is a prescription medication approved to treat mild-to-moderate pain, with or without a fever. It contains two active ingredients: propoxyphene (a narcotic) and acetaminophen (a pain reliever and fever reducer commonly found in over-the-counter drugs).
Propoxyphene is classified as a mild, centrally acting, narcotic pain reliever. "Centrally acting" means that it works in the central nervous system (the brain and spinal cord). Propoxyphene is chemically related to methadone. The other active ingredient, acetaminophen, is commonly found in non-prescription medications such as Tylenol®. Adding acetaminophen to propoxyphene boosts the effects of Darvocet for relieving pain and also provides fever-reducing properties.
