Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehabilitation facility who realize how difficult and challenging 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 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 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 further treatment services to deal with all addiction issues.
