Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehabilitation program who realize how difficult and challenging methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals frequently revert back to methadone to relieve 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 rehab program which has practical experience in dealing with this type of detoxification, and where the individual can receive further treatment services to deal with all addiction issues.
