Uses

This medication is used to treat certain bowel disorders (ulcerative colitis, Crohn's disease). In these conditions, the body's defense system (immune system) attacks healthy tissues in the gut, causing symptoms such as abdominal pain, blood in the stool, and diarrhea. Vedolizumab belongs to a class of drugs known as monoclonal antibodies. It works by blocking the actions of a certain natural substance (integrin) in the body. This helps to decrease swelling (inflammation) in the gut, which lessens symptoms and may slow or stop damage from these bowel disorders.

How To Use

Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start using vedolizumab and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

If you are using this medication at home, learn all preparation and usage instructions from your health care professional.
