Methadone detoxification is a course of action which should be overseen by substance abuse professionals within a drug rehab program who recognize how difficult and challenging methadone detox can be. Methadone detoxification is regarded to be far more severe 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 detoxification must only be done under close supervision at a drug rehab facility which has experience in handling this type of detox, and where the person can receive further treatment services to deal with all addiction issues.
