Darvocet-N Propoxyphene is in a group of drugs called narcotic pain relievers. Acetaminophen is a less potent pain reliever and a fever reducer that increases the effects of propoxyphene. The combination of acetaminophen and propoxyphene is used to relieve mild to moderate pain with or without fever.
Propoxyphene may be habit-forming and should be used only by the person it was prescribed for. Keep the medication in a secure place where others cannot get to it. Do not use Darvocet if you have taken an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) in the last 14 days. Serious, life threatening side effects can occur if you use Darvocet before the MAO inhibitor has cleared from your body.
