What is Darvocet and how is it used

Structurally, it's a relative of the synthetic narcotic, methadone. It's prescribed in two forms- propoxyphene hydrochloride and propoxyphene napsylate -for relief of mild to moderate pain.

Aside from slight differences-the napsylate (or N-form) of propoxyphene is more slowly absorbed in the body and so has a longer duration of action-the two drugs are identical. Both are found in a number of prescription pain medications, including:

• Darvon and Darvon-N (propoxyphene only)
• Darvon with A.S.A., Darvon-N with A.S.A. (with aspirin)
• Darvocet, Darvocet-N, Wygesic (with acetaminophen)
• Darvon Compound, Darvon Compound-65 (with aspirin and caffeine)

Darvocet when abused is taken orally, chewed, crushed (then snorted like cocaine), or crushed (then dissolved in water and injected like heroin).
