Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehabilitation facility who recognize how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and users 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 detoxification must only be done under close supervision at a drug rehab facility which has practical experience in handling this type of detoxification, and where the person can receive additional treatment services to address all addiction issues.
