Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation facility who understand how challenging and difficult methadone detox can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and individuals 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 detox 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.
