Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehabilitation 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 often revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab facility which has practical experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to deal with all addiction issues.
