Giant cell arteritis (GCA) is typically treated with high doses of corticosteroids. Corticosteroids should be started promptly (perhaps even before the diagnosis is confirmed with a biopsy). If not treated promptly, the condition carries a small risk of blindness. The symptoms of GCA usually quickly disappear with treatment, but high doses of corticosteroids are typically maintained for 1 month. Once symptoms are gone and the sed rate is normal, there is much less risk of blindness and the corticosteroid dose may be gradually reduced. Other medications that suppress the immune system are sometimes also needed.
