Why is this medication prescribed?
Vedolizumab injection is used to relieve the symptoms of certain autoimmune disorders (conditions in which the immune system attacks healthy parts of the body and causes pain, swelling, and damage) of the gastrointestinal tract including:
- Crohn’s disease (a condition in which the body attacks the lining of the digestive tract, causing pain, diarrhea, weight loss, and fever) that has not improved when treated with other medications.
- Ulcerative colitis (condition that causes swelling and sores in the lining of the large intestine) that has not improved when treated with other medications.
Vedolizumab injection is in a class of medications called integrin receptor antagonists. It works by blocking the action of certain cells in the body that cause inflammation.
How should this medicine be used?
Vedolizumab injection comes as a powder to be mixed with sterile water and injected intravenously (into a vein) over 30 minutes by a doctor or nurse. It is usually given in a doctor’s office once every 2 to 8 weeks, more often in the beginning of your treatment and less often as your treatment continues.
Vedolizumab injection may cause serious allergic reactions during an infusion and for several hours afterward. A doctor or nurse will monitor you during this time to be sure you are not having a serious reaction to the medication. You may be given other medications to treat reactions to vedolizumab injection. Tell your doctor or nurse immediately if you experience any of the following symptoms during or after your infusion: rash; itching; swelling of the face, eyes, mouth, throat, tongue, or lips; difficulty breathing or swallowing; wheezing, flushing; dizziness; feeling hot; or a fast or racing heartbeat.
Vedolizumab injection may help control your symptoms, but it will not cure your condition. Your doctor will watch you carefully to see how well vedolizumab injection works for you. If your condition has not improved after 14 weeks, your doctor may stop treating you with vedolizumab injection. It is important to tell your doctor how you are feeling during your treatment.
Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with vedolizumab injection and each time you receive the medication. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer’s website to obtain the Medication Guide.
