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 approved for the treatment of mild-to-moderate pain. It comes in capsule form and is generally taken every four hours as needed for pain relief. While most people have no problems during treatment, there are some important risks with Darvon you should be aware of.
For example, Darvon is considered a desirable drug of abuse because it is a narcotic medication. People with a history of drug or alcohol abuse may need to take a different pain medication.
Side effects are also possible with this medicine. Common ones include nausea, drowsiness, and dizziness. In rare cases, potentially serious side effects, such as allergic reactions, seizures, or hallucinations, can occur.
