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