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.
Darvon® (propoxyphene hydrochloride) is a drug used to treat mild-to-moderate pain. Sold as capsules (pills), Darvon is only available in one strength -- 65 mg. At one point, there was a 32-mg capsule, but this particular strength is no longer available.
This narcotic medication is taken by mouth, usually every four hours as needed for pain. However, do not take more than 6 capsules in a 24-hour period. Be careful not to exceed this maximum recommended daily dose, as this could lead to potentially lethal overdose symptoms.
