Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug treatment program who realize how challenging and difficult 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 often revert back to methadone to alleviate 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 experience in dealing with this type of detoxification, and where the individual can receive additional rehabilitation services to deal with all addiction issues.
