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