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