Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation program who realize how difficult and challenging 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 often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox must only be done under strict supervision at a drug rehabilitation facility which has practical experience in handling this type of detox, and where the person can receive additional rehabilitation services to deal with all addiction issues.
