Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehabilitation facility who realize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and individuals frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate 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 rehabilitation services to handle all addiction issues.
