Methadone detoxification is a course of action which should be overseen by addiction 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 users 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 strict supervision at a drug rehabilitation facility which has experience in dealing with this type of detox, and where the person can receive further rehabilitation services to address all addiction issues.
