There are several types of medications that are used to help control IBD.  Aminosalicylates target colon inflammation, but are less effective at treating the small intestine. These drugs are usually used to treat mild to moderate colitis. Sulfasalazine is effective, but side effects include nausea, vomiting, diarrhea, heartburn, and headache. Corticosteroids fight inflammation, but suppress all immune response instead of focusing on the colon. These drugs (prednisone, methylprednisolone) are used for moderate to severe colitis. Side effects include weight gain, excessive facial hair growth, mood swings, high blood pressure, type 2 diabetes, osteoporosis, bone fractures, cataracts, glaucoma, and an increased risk of infection. Azathioprine and mercaptopurine act slowly, so they're usually prescribed alongside a corticosteroid. Immunomodulators, like corticosteroids, suppress immune response to calm inflammation. They're usually used only when aminosalicylates and corticosteroids have failed. Cyclosporine is a very strong medication that begins to work within one or two weeks. Since it is so strong and comes with a range of severe side effects, it is generally only prescribed until less toxic medications can take effect. Infliximab and adalimumab fight intestinal inflammation specifically.  Infliximab can cause problems in people with cancer or a history of heart disease. Antibiotics don't treat the colitis itself. If intestinal ulcers cause infection though, antibiotics will prevent further complications.  Antibiotics can treat abscesses of fistulas (abnormal connections between organs or vessels) seen in Crohn's Disease and usually occurring in the small intestine.  Tell your doctor if you develop a fever, which could indicate infection. Though it may sound "natural" or "herbal," biologic therapies take their name from the fact that they're developed from biological material — usually protein. This treatment targets the chemicals responsible for inflammation. These fairly new medications are used for moderate...
