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.
There is only one strength of Darvon® (propoxyphene hydrochloride) available -- 65-mg capsules. Typically, the recommended Darvon dosage for treating mild-to-moderate pain is one capsule taken every four hours as needed.
Although there is only one Darvon strength, the exact amount of your dosage will depend on various factors, such as if you are taking any other medications and how you respond to Darvon initially. For example, if your kidney or liver function is not optimal, your healthcare provider may decide to prescribe a lower Darvon dosage.
