Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehab program who realize how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and users often 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 experience in dealing with this type of detoxification, and where the person can receive further recovery services to deal with all addiction issues.
