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