Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehabilitation facility who understand 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 ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox should only be done under close supervision at a drug rehab facility which has practical experience in dealing with this type of detoxification, and where the individual can receive additional rehabilitation services to address all addiction issues.
