Methadone detoxification is a process which should be supervised by addiction professionals within a drug rehab program who recognize how difficult and challenging methadone detox can be. Methadone detox is known 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 relieve symptoms. This is why methadone detoxification should only be done under strict supervision at a drug rehabilitation facility which has practical experience in dealing with this type of detox, and where the person can receive further treatment services to deal with all addiction issues.
