Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab center who recognize how difficult and challenging 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 relieve 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 rehabilitation facility which has experience in dealing with this type of detox, and where the person can receive additional treatment services to handle all addiction issues.
