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