Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug treatment center who realize how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more severe 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 detox must only be done under close supervision at a drug rehabilitation center which has experience in handling this type of detoxification, and where the person can receive additional rehabilitation services to deal with all addiction issues.
