Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehabilitation program who recognize how difficult and challenging methadone detoxification 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 ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehab facility which has practical experience in dealing with this type of detox, and where the individual can receive additional treatment services to handle all addiction issues.
