Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation program who realize how difficult and challenging methadone detox can be. Methadone detox 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 alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehabilitation center which has practical experience in handling this type of detoxification, and where the individual can receive further rehabilitation services to handle all addiction issues.
