What is the most important information I should know about acetaminophen and propoxyphene (Darvocet-N)?

Acetaminophen and propoxyphene was withdrawn from the U.S. market in November 2010.

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 acetaminophen and propoxyphene 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 acetaminophen and propoxyphene before the MAO inhibitor has cleared from your body.
