Corticosteroid medications mimic the effects of the hormones that the adrenal glands on top of the kidneys produce, explains Mayo Clinic. They help suppress inflammation and the immune system, making them useful for treating conditions related to swelling and autoimmune disorders. Oral corticosteroid medications are often prescribed to treat rheumatoid arthritis and lupus, while inhaled preparations of these drugs may be prescribed for asthma. Topical creams containing corticosteroids may be used to heal skin conditions, and injections of these drugs are useful to reducing the pain and inflammation of tendinitis.
Dr. Shiel: Fortunately, the rounding of the face, which occurs because of cortisone medications, is often times reversible. This usually occurs because of a re-distribution of fatty tissue and enlargement of fat in and around the face so that what is commonly referred to as a "moon face" can occur with prolonged cortisone use. This often times is a temporary phenomenon. There are a limited number of patients who unfortunately, this is not reverse in, but most often does reverse over time after the medicines are discontinued.
