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