Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation facility who recognize how difficult and challenging methadone detox can be. Methadone detox is known to be far more serious 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 ease symptoms. This is why methadone detox must only be done under strict supervision at a drug rehabilitation facility which has practical experience in handling this type of detoxification, and where the person can receive additional treatment services to deal with all addiction issues.
