Sulfasalazine is used for the treatment of ulcerative colitis in adults and children age six and up. It is believed to work by inhibiting the action of certain chemicals in the colon that cause inflammation. As a result, symptoms of ulcerative colitis are diminished. Off-label sulfasalazine uses may include the treatment of Crohn's disease and rheumatoid arthritis.
