What is Entyvio?

Entyvio (vedolizumab) reduces the effects of a substance in the body that can cause inflammation.

Entyvio is used in adults with moderate to severe ulcerative colitis (UC), or moderate to severe Crohn's disease.

Entyvio treats active disease and may help keep UC or Crohn's symptoms under control long term. Vedolizumab may also reduce the need for steroid medicines in helping to control symptoms long term.

Entyvio is usually given after other medicines have been tried without success.

Important information

You should not use Entyvio if you are allergic to vedolizumab.

Do not receive a "live" vaccine while using Entyvio.

Call your doctor right away if you have any change in your mental state, decreased vision, or problems with speech or walking.

Before taking this medicine

To make sure Entyvio is safe for you, tell your doctor if you have:

  • an active or recent infection;

  • tuberculosis (or if you have close contact with someone who has tuberculosis);

  • signs of infection such as fever, cough, or flu symptoms;

  • open sores or skin wounds;

  • weak immune system (caused by disease or by using certain medicine); or

  • if you are scheduled to receive any vaccines.

You should be up to date with all needed vaccinations before receiving Entyvio.

FDA pregnancy category B. Entyvio is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.

If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of Entyvio on the baby.

It is not known whether vedolizumab passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

Do not give Entyvio to anyone under 18 years old without medical advice.

How is Entyvio given?

Before you start treatment with Entyvio, your doctor may perform tests to make sure you do not have tuberculosis or other infections.

Entyvio is injected into a vein through an IV. A healthcare provider will give you this injection.

Entyvio must be given slowly, and the IV infusion can take about 30 minutes to complete.

You will be watched closely for a short time after receiving your dose, to make sure you do not have an allergic reaction to the medication.

Entyvio is usually given on a schedule that starts the day of your first injection. Your next injections will be given at 2 weeks and 6 weeks after the first injection. Then you will receive an injection every 8 weeks (or every 2 months) thereafter.

It may take up to several weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve after 14 weeks of treatment.

What happens if I miss a dose?

Call your doctor for instructions if you miss an appointment for your Entyvio injection.

What happens if I overdose?

Since this medicine is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

What should I avoid while receiving Entyvio?

Do not receive a "live" vaccine while using Entyvio, and avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.

You may receive "killed-virus" vaccines such as a flu shot, polio vaccine, rabies vaccine, or hepatitis A vaccine. Ask your doctor before receiving any vaccine while you are being treated with Entyvio.

Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.
