Taking TYSABRI

1 infusion each month (every 28 days)

With TYSABRI, trained healthcare professionals administer your relapsing MS infusion* every 28 days. The actual infusion takes about an hour. You’re then asked to stay for another hour just to make sure you’re not having an infusion-related reaction that may need medical attention.

*Infusion given through a needle placed in your vein (IV infusion).

It’s important to:

dress comfortably and drink plenty of water on TYSABRI infusion day. And remember, the infusion center may be a great place to meet others who are choosing to fight their relapsing MS.

Here are some activities you can do while getting your TYSABRI infusion:

Read books or magazines

Play games

Catch up on sleep

Work on your laptop

Listen to
music

Chat with others

The TOUCH Prescribing Program is in your corner

Because TYSABRI may increase your risk of developing progressive multifocal leukoencephalopathy (PML), you can receive it only through the TOUCH® Prescribing Program.

Infusion centers, doctors’ offices, and hospitals authorized by the TOUCH program are staffed by nurses who are committed to your safety. In addition to educating you on the potential risks of TYSABRI, they are there to answer any infusion questions you may have and ask you a series of questions before each infusion to make sure TYSABRI is still right for you.

Talk to the nurse before each TYSABRI infusion. Ask questions and share any new or ongoing medical conditions such as:
  • Any new or worsening problems that have lasted several days
  • If you’ve had hives, itching, or trouble breathing during or after an infusion
  • If you’ve had a fever or infection
  • If you are taking any other medications, including prescription and nonprescription medicines, vitamins, and herbal supplements

How TYSABRI may work

What is TYSABRI?

TYSABRI is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. TYSABRI increases the risk of progressive multifocal leukoencephalopathy (PML). When starting and continuing treatment with TYSABRI, it is important to discuss with your doctor whether the expected benefit of TYSABRI is enough to outweigh this risk. 

It is not known if TYSABRI is safe and effective in children under 18 years of age.

IMPORTANT SAFETY INFORMATION

What is the most important information I should know about TYSABRI?

TYSABRI increases your risk of getting a rare brain infection—called progressive multifocal leukoencephalopathy (PML)—that usually leads to death or severe disability.

  • There is no known treatment, prevention, or cure for PML
  • You should not take certain medicines that weaken your immune system at the same time you are taking TYSABRI. Even if you use TYSABRI alone to treat your MS, you can still get PML
  • Your risk of getting PML is higher if you:
    • have been infected by the John Cunningham Virus (JCV). JCV is a common virus that can cause PML in people who have weakened immune systems, such as people taking TYSABRI. Before or while you receive TYSABRI, your doctor may do a blood test to check if you have been infected by JCV
    • have received TYSABRI for a long time, especially for longer than 2 years
    • have received certain medicines that can weaken your immune system before you start receiving TYSABRI
  • Your risk of getting PML is greatest if you have all 3 risk factors listed above. There may be other risk factors that have not yet been identified
  • Patients who are anti-JCV antibody negative are still at risk for the development of PML due to the potential for a new JCV infection or a false negative test result. Therefore, patients with a negative test result should be retested periodically
  • While you receive TYSABRI, and for 6 months after you stop receiving TYSABRI, it is important that you call your doctor right away if you have any new or worsening medical problems (such as problems with your thinking, eyesight, balance, or strength; weakness on 1 side of your body; and using your arms and legs) that have lasted several days. Tell all of your doctors that you are getting treatment with TYSABRI
  • Because of your risk of getting PML while you receive TYSABRI, TYSABRI is available only through a restricted distribution program called the TOUCH® Prescribing Program

Who should not receive TYSABRI?

Do not receive TYSABRI if you have PML or are allergic to natalizumab or any of the ingredients in TYSABRI.

What should I tell my doctor before receiving each dose of TYSABRI?

Before receiving TYSABRI, it is important to tell your doctor:

  • If you have a medical condition that can weaken your immune system, such as HIV infection or AIDS, leukemia or lymphoma, organ transplant, or others, or if you have any new or worsening medical problems that have lasted several days
  • If you are pregnant or plan to become pregnant or if you are breastfeeding or plan to breastfeed. It is not known if TYSABRI can harm your unborn baby or if the TYSABRI that passes into your breast milk can harm your baby
  • About all of the medicines and supplements you take, especially medicines that can weaken your immune system. If you are not sure, ask your doctor

What are the possible side effects of TYSABRI?

TYSABRI can cause serious side effects. If you have any of the symptoms listed below, call your doctor right away:

  • Herpes infections. Increased risk of infection of the brain or the covering of your brain and spinal cord (encephalitis or meningitis) caused by herpes viruses that may lead to death. Symptoms include sudden fever, severe headache, or confusion. Infection of the eye caused by herpes viruses leading to blindness in some patients has occurred. Call your doctor if you have changes in vision, redness, or eye pain
  • Liver damage. Symptoms include yellowing of the skin and eyes (jaundice), unusual darkening of the urine, nausea, feeling tired or weak, or vomiting
  • Allergic reactions (e.g., hives, itching, trouble breathing, chest pain, dizziness, wheezing, chills, rash, nausea, flushing of skin, low blood pressure), including serious allergic reactions (e.g., anaphylaxis). Serious allergic reactions usually happen within 2 hours of the start of the infusion, but they can happen any time after receiving TYSABRI
  • Weakened immune system. TYSABRI may increase your risk of getting an unusual or serious infection
  • Low platelet counts. TYSABRI may cause the number of platelets in your blood to be reduced. Symptoms include easy bruising, small scattered red spots on your skin that are red, pink or purple, heavier menstrual periods than are normal, bleeding from your gums or nose that is new or takes longer than usual to stop, bleeding from a cut that is hard to stop

The most common side effects of TYSABRI are:

  • Headache, urinary tract infection, lung infection, pain in your arms and legs, vaginitis, stomach-area pain, feeling tired, joint pain, depression, diarrhea, rash, nose and throat infections, and nausea. If you experience any side effect that bothers you or does not go away, tell your doctor

These are not all of the possible side effects of TYSABRI. For more information, ask your doctor. To report side effects to FDA, please call 1-800-FDA-1088.
