Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehab facility who realize how difficult and challenging methadone detox can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals 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 detox must only be done under strict supervision at a drug rehabilitation facility which has practical experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to handle all addiction issues.
