It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Vedolizumab may cause an infusion reaction while you are receiving it or right after the infusion ends. Check with your doctor or nurse right away if you have chest pain, a fever, chills, itching, hives, a rash, dizziness, fainting, lightheadedness, a headache, joint pain, difficulty with swallowing, trouble breathing, or swelling of the face, tongue, and throat.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth with this medicine.

Your body's ability to fight an infection may be reduced with this medicine. Avoid being near people who are sick and wash your hands often. Tell your doctor if you have ever had an infection that would not go away or an infection that kept coming back.
