Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehab facility who recognize how challenging and difficult methadone detoxification can be. Methadone detoxification 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 relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox must only be done under close supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the person can receive further rehabilitation services to handle all addiction issues.
