Pentazocine, sold under the brand name Talwin among others, is a opioid used to treat moderate to severe pain. It may be taken by mouth or used by injection. Onset of effects begin with 30 min when taken by mouth and last for more than 3 hours. It is generally a less preferred medication.

Common side effects include dizziness, felling high, sleepiness, and nausea. Other side effects may include seizures, abuse, insufficient breathing (respiratory depression), serotonin syndrome, and adrenal insufficiency. It should not be used in people with opioid dependence as may precipitate opioid withdrawal. It is a partial agonist of the opioid receptor.

Pentazocine was patented in 1960 and approved for medical use in 1964. It is available as a generic medication. In the United States 120 tablets of 50 mg costs about 80 USD as of 2021. This amount in the United Kingdom costs the NHS about £12o. The tables come combined with naloxone to try to decrease misuse.
