Methadone detoxification is a course of action which must be overseen by substance abuse professionals within a drug rehab facility who realize how challenging and difficult methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals often revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehabilitation program which has practical experience in dealing with this type of detox, and where the individual can receive additional recovery services to handle all addiction issues.
