Methadone detoxification is a course of action which must be overseen by addiction professionals within a drug treatment facility who realize how challenging and difficult methadone detox can be. Methadone detoxification 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 relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the person can receive additional rehabilitation services to deal with all addiction issues.
