Darvocet (acetaminophen and propoxyphene) was withdrawn from the U.S. market in November 2010.

Darvocet contains a combination of propoxyphene and acetaminophen. 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.

Darvocet is used to relieve mild to moderate pain with or without fever.
