Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab facility who recognize how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users often 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 must only be done under close supervision at a drug treatment facility which has practical experience in handling this type of detox, and where the individual can receive further rehabilitation services to address all addiction issues.
