Methadone detoxification is a course of action which should be overseen by substance abuse professionals within a drug rehab program who realize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and individuals frequently 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 close supervision at a drug rehabilitation facility which has experience in dealing with this type of detox, and where the person can receive additional rehabilitation services to deal with all addiction issues.
