Propoxyphene (Darvon®)

Propoxyphene is a synthetic opioid that is typically prescribed to treat mild to moderate pain. Propoxyphene is no longer available in the US (stopped being supplied in the US as of November 19, 2010) due to clinical data from the FDA that demonstrated that propoxyphene puts patients at risk of potential serious or even fatal heart rhythm abnormalities. People who abuse propoxyphene do so because it provides a stronger feeling of calm and euphoria.
