Colazal^® (balsalazide disodium) is used to treat ulcerative colitis -- a type of inflammatory bowel disease -- in adults and children ages five and older. The drug is thought to work by decreasing the production of certain chemicals that lead to inflammation and symptoms such as rectal bleeding. Colazal comes in capsule form, and is usually taken three times a day.

 

Side effects of Colazal can include abdominal pain (or stomach pain), gas, and a fever. Among the conditions that you should tell your healthcare provider about prior to taking Colazal are pyloric stenosis (a narrowing of the outlet of the stomach), kidney disease, and any allergies you may have (including allergies to food, dyes, or preservatives).
