Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation 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 users typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehabilitation program which has practical experience in dealing with this type of detox, and where the person can receive further rehabilitation services to address all addiction issues.
