These fast-acting anti-inflammatory drugs are used to treat acute (sudden onset and/or short duration) flare-ups. Because of their known side effects, doctors like to either avoid them completely or prescribe them for a short time. Corticosteroids can be given orally, rectally or intravenously. Examples of corticosteroids are prednisone, prednisolone, or methylprednisolone. Budesonide is a slightly different type of steroid, as very little gets absorbed into the body, so side effects are much less frequent.
