Methadone detoxification is a course of action which should be overseen by substance abuse professionals within a drug rehab facility who realize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification should 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 address all addiction issues.
