What is Darvocet?
- Darvocet is a drug that combines propoxyphene and acetaminophen. Propoxyphene belongs to the class of drugs known as narcotic pain relievers. Acetaminophen is a non-opioid pain reliever that enhances the effects of propoxyphene.
- Darvocet helps treat mild to moderate pain that is associated with or without fever. Darvocet is no longer available in the United States. There may be generic versions available. You can order Darvocet online or from a local pharmacy store.
Propoxyphene can be habit-forming. Keep Darvocet in a safe place where others will not be able to access it. Do not take an MAO inhibitor in the last 14 days, such as isocarboxazid (Marplan), furazolidone (Furoxone), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate), do not take Darvocet.
