Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehabilitation program who recognize how difficult and challenging methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox should only be done under close supervision at a drug rehabilitation facility which has practical experience in handling this type of detoxification, and where the person can receive further treatment services to handle all addiction issues.
