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.
Available only by prescription, Darvon
® (
propoxyphene hydrochloride) is a medication used for pain relief. It comes in capsule form and is taken every four hours as needed to relieve mild-to-moderate pain. No more than six capsules should be taken in a 24-hour period. As a narcotic and
controlled substance, Darvon has a high potential for abuse and addiction. Abuse, however, can be difficult to distinguish from just a simple physical dependence on the medication.
As with any medicine, side effects are possible. In clinical studies, some of the most common side effects seen with Darvon included drowsiness, dizziness, and nausea. This drug is not suitable for everyone. Before taking Darvon, tell your healthcare provider if you are taking any other medications or have a history of drug or alcohol dependence.
