Subuxone was FDA approved in 2002 for the treatment of opiate addiction
The Food and Drug Administration (FDA) announced the approval of Subutex (buprenorphine hydrochloride) and Suboxone tablets (buprenorphine hydrochloride and naloxone hydrochloride) for the treatment of opiate dependence. Subutex and Suboxone treat opiate addiction by preventing symptoms of withdrawal from heroin and other opiates.''
Just this year a sub-lingual form of Suboxone was FDA approved - again for opiate addiction. Physicians do need to get approval to prescribe this drug.
Judging from responses on the internet, some people, are, however, being prescribed this drug to control pain. It does appear to be licensed to treat pain in Europe.
