Selected Important Safety Information:

NULOJIX increases your risk of serious side effects, including post-transplant lymphoproliferative disorder (PTLD), cancers other than PTLD, progressive multifocal leukoencephalopathy (PML, a rare, serious brain infection), and other serious infections caused by bacteria (including tuberculosis [TB]), viruses, or fungi. Scroll down for detailed and additional Important Safety Information, including bolded text.


What is the most important information I should know about NULOJIX® (belatacept)?

  • NULOJIX increases your risk of serious side effects, including:

Post-transplant lymphoproliferative disorder (PTLD), a condition that can happen if certain white blood cells grow out of control because of a weakened immune system.

  • PTLD can worsen, become a type of cancer, and can lead to death
  • NULOJIX increases the risk of getting PTLD; if you get PTLD with NULOJIX, you are at especially high risk of PTLD in your brain
  • Your risk for PTLD is also higher if you:
    • have never been exposed to the Epstein-Barr virus (EBV). Your doctor will test you for EBV exposure. Do not receive NULOJIX unless you are EBV positive (you have been exposed to EBV).
    • get an infection with cytomegalovirus (CMV)
    • receive treatment for transplant rejection that lowers certain white blood cells (T cells)


Other cancers, including skin cancer due to a weakened immune system.

  • Limit the amount of time you spend in sunlight, wear protective clothing, use sunscreen with a high SPF, and avoid using tanning beds or sunlamps


Progressive multifocal leukoencephalopathy (PML), a rare, serious brain infection caused by JC virus due to a weakened immune system.

  • PML can result in death or severe disability
  • There is no known prevention, treatment, or cure for PML


Other serious infections, including tuberculosis (TB) and infections caused by bacteria, viruses, or fungi

  • These serious infections may lead to death
  • The BK virus can affect how your kidney works and cause your transplanted kidney to fail


  • Tell your doctor right away if you get any of these symptoms during treatment with NULOJIX:
  • change in mood or your usual behavior
  • confusion or problems with thinking or memory
  • change in the way you walk or talk
  • decreased strength or weakness on one side of your body
  • change in vision
  • fever, night sweats, or tiredness that does not go away
  • weight loss
  • swollen glands
  • flu, cold symptoms, or cough
  • stomach-area pain
  • vomiting or diarrhea
  • tenderness over transplanted kidney
  • change in amount of urine that you make, blood in your urine, pain, or burning upon urination
  • new skin lesion or bump, or change in size or color of a mole


  • Liver transplant patients should not receive NULOJIX due to increased risk of loss of transplanted liver and death.
