Methadone detoxification is a course of action which should be overseen by substance abuse professionals within a drug rehabilitation facility who understand how difficult and challenging methadone detoxification 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 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 dealing with this type of detox, and where the individual can receive further treatment services to deal with all addiction issues.
