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