Data regarding prevalence of Pentazocine use is sparse and intervention strategies aimed at it are meager. In view of the fact that Pentazocine has significant abuse potential contrary to what was earlier thought, along with the actuality that people who use injectable Pentazocine are at risk of various complications as HIV, this domain needs more attention. This review examines the extent of the problem of Pentazocine use with consequent effects on the overall health of the people. It is based on nationally representative large scale survey(s) and other reliable documented data on Pentazocine abuse. Possible strategies and future lines of actions have been delineated. Data suggests Pentazocine use from 0.1% to 21.8% in different parts of the country. Various reports have also linked it with unique health complications. Its use has been reported mostly among subjects seeking treatment, with recent reports suggesting increasing use at street level. The strategies to document the extent of injection drug use applied in most cases might not be adequate. There is a need for further research and monitoring to document the burden of the problem. Indirect methods to estimate the extent of problem may need to be implemented and regulatory mechanisms for prescription drug use may need to be strengthened.
