Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug treatment facility who realize how difficult and challenging methadone detoxification can be. Methadone detox is known 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 ease symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehabilitation facility which has experience in handling this type of detox, and where the person can receive further rehabilitation services to handle all addiction issues.
