Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab program who realize how challenging and difficult methadone detoxification 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 relieve symptoms. This is why methadone detox must only be done under strict 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.
