Methadone detoxification is a course of action which must be supervised by addiction professionals within a drug rehabilitation 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 typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox must only be done under strict supervision at a drug rehabilitation program which has experience in dealing with this type of detox, and where the person can receive further rehabilitation services to deal with all addiction issues.
