Available in the form of a tablet, pentazocine/naloxone is prescribed for use in people who have moderate-to-severe pain. This medicine is a type of controlled substance, meaning it is highly regulated and has a potential for abuse. It is usually taken every three or four hours. Although most people tolerate this pain reliever well, side effects are possible and include headaches, sweating, and constipation.
What Is Pentazocine/Naloxone?
Pentazocine/naloxone (Talwin® Nx) is a prescription medication approved to treat moderate-to-severe pain. It contains a combination of two active ingredients: pentazocine (Talwin®), a potent pain reliever, and naloxone (Narcan®), which is added to help deter misuse of pentazocine/naloxone by injection.
Pentazocine/naloxone is considered a schedule IV controlled substance because it has the potential for abuse or addiction. As a controlled substance, the possession and use of the drug are highly regulated. Schedule IV substances are considered to have less abuse potential than schedule II drugs, such as morphine, or schedule III drugs, such as hydrocodone/APAP.
