Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab facility who understand how challenging and difficult methadone detoxification can be. Methadone detoxification is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users typically 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 should only be done under close supervision at a drug rehab facility which has experience in dealing with this type of detoxification, and where the person can receive further treatment services to handle all addiction issues.
