Methadone detoxification is a course of action which should be supervised by drug addiction professionals within a drug rehab facility who recognize how difficult and challenging methadone detoxification can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox 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.
