Features

• Darvon contains only propoxyphene. Darvocet is a combination of propoxyphene and acetaminophen, which is the primary ingredient in some over-the-counter pain relievers, such as Tylenol. Both are prescribed for mild to moderate pain.
  
  

Function

• As a non-narcotic that raises the pain threshold, the inclusion of acetaminophen with propoxyphene (Darvocet) can offer more pain relief than propoxyphene alone (Darvon).
  
  

History

• From its approval in 1957, Darvon was the trade name for dispensing propoxyphene. In 1972, the FDA approved the propoxyphene/acetaminophen combination in one pill.
  
  

Habit-Forming

• As a narcotic similar to the synthetic methadone, propoxyphene is addictive and will cause withdrawal symptoms if not taken in accordance with instructions.
  
  

Warning

• The use of either Darvon or Darvocet in combination with alcohol, sedatives, or anti-depressants can have dangerous consequences. Breathing can be depressed so much as to cause death.
