Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehabilitation program who understand how challenging and difficult methadone detox can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate 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 detoxification, and where the person can receive further treatment services to address all addiction issues.
