Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehabilitation program who recognize 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 individuals frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the individual can receive further rehabilitation services to deal with all addiction issues.
