Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug treatment facility who realize how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and individuals typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the person can receive additional treatment services to handle all addiction issues.
