How does this medication work? What will it do for me?
Vedolizumab belongs to the class of medications called biologic response modifiers. It is used for the treatment of adults with moderately to severely active ulcerative colitis or Crohn’s disease when there has been a poor response to other treatments, or these treatments are no longer effective or have unacceptable side effects.
Ulcerative colitis is a disease in which the large bowel becomes inflamed, resulting in symptoms such as abdominal pain and cramping, diarrhea, rectal pain, and rectal bleeding. Crohn’s disease is a disease where there is chronic inflammation of the gastrointestinal tract. This medication works specifically in the digestive system to reduce the activity of a protein that causes the inflammation that causes the symptoms of ulcerative colitis and Crohn’s disease.
