Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug treatment program who recognize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehabilitation facility which has experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to deal with all addiction issues.
