Methadone detoxification is a course of action which must be overseen by substance abuse 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 frequently 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 treatment facility which has experience in handling this type of detoxification, and where the individual can receive further rehabilitation services to deal with all addiction issues.
