Treatment. It is very important that no laxatives, such as castor oil, be given to a person with appendicitis. Laxatives should never be given to a person with an abdominal disorder that might be appendicitis. Any such medicines may cause the appendix to rupture, spreading bacteria through the abdomen. The patient should remain quiet. A doctor should be called immediately. The usual treatment for acute appendicitis is surgical removal of the appendix, an operation known as an appendectomy. In mild cases, the inflammation may subside by itself. Some people may have recurrent appendicitis.
