Darvocet is a combination of acetaminophen (Tylenol) and propoxyphene designed to relieve mild to moderate pain. Propoxyphene binds to the pain receptors in the brain so that the sensation of pain is reduced. Acetaminophen halts the production of prostaglandins which otherwise cause pain. It is formulated as a tablet taken every 4 hours by mouth. Since propoxyphene can be habit forming, care must be taken to follow the doctor's instructions when taking Darvocet. Do not take a larger dose, or take it more frequently, or take it for longer than the doctor has prescribed.
