When it comes to ulcerative colitis, there are different options for treatment. Many different kinds of drugs are available. The treatment your doctor prescribes for you often depends on the severity of your symptoms.

Two drugs you may hear about are prednisone and prednisolone. (A third drug, methylprednisolone, is stronger than both and should not be confused with prednisolone.) Here’s the rundown on what these drugs are and how they can help treat ulcerative colitis, including how they’re alike and how they’re different.

Prednisone and prednisolone both belong to a class of drugs called glucocorticoids. Glucocorticoids reduce inflammation throughout your body. They do this by interfering with the way certain chemicals in your body cause inflammation.

These drugs can work in different parts of your body, including your colon. Your colon is the last section of your large intestine, just before your rectum. By reducing the inflammation there, these drugs help reduce the damage that colitis does to your colon.

Neither of these drugs cures colitis, but both can help control it and improve your quality of life. These drugs relieve common symptoms such as:

  • stomach cramps and pain
  • weight loss
  • diarrhea
  • fatigue
