Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab program who recognize how difficult and challenging methadone detox can be. Methadone detoxification is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users often 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 should only be done under close supervision at a drug rehab facility which has practical experience in dealing with this type of detoxification, and where the person can receive additional recovery services to deal with all addiction issues.
