Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehab center who realize how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals frequently 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 should only be done under strict supervision at a drug rehab facility which has experience in handling this type of detox, and where the person can receive additional treatment services to handle all addiction issues.
