Methadone and Suboxone have been used successfully to treat narcotic addiction for many years in the United States. Both medications are used in the long-term maintenance treatment of narcotic dependency. Methadone and Suboxone are opioids as are heroin, hydrocodone, fentanyl, and other narcotic pain medications. The medicines bind to the same places in the brain as other opiates. In opioid misuse treatment, they prevent cravings and allow people to transition back from a life of addiction to relative normalcy and safety.
