What is infliximab?
Infliximab reduces the effects of a substance in the body that can cause inflammation.
Infliximab is used to treat rheumatoid arthritis, psoriatic arthritis, ulcerative colitis, Crohn's disease, and ankylosing spondylitis. Infliximab is also used to treat severe or disabling plaque psoriasis.
Infliximab is often used when other medicines have not been effective.
Infliximab may also be used for purposes not listed in this medication guide.
Using infliximab may increase your risk of developing certain types of cancer, including a rare fast-growing type of lymphoma that can be fatal. Ask your doctor about your specific risk.
Infliximab affects your immune system. You may get infections more easily, even serious or fatal infections. Call your doctor if you have a fever, tiredness, flu symptoms, cough, or skin pain.
Before taking this medicine
You should not be treated with infliximab if you are allergic to it.
Tell your doctor if you have ever had tuberculosis, if anyone in your household has tuberculosis, or if you have recently traveled to an area where certain infections are common (Ohio River Valley, Mississippi River Valley, and the Southwest).
Tell your doctor if you have ever had:
heart failure or other heart problems;
an active infection (fever, cough, flu symptoms, open sores or skin wounds);
liver failure, hepatitis B, or other liver problems;
a weak immune system;
numbness or tingling anywhere in your body;
a nerve-muscle disorder, such as multiple sclerosis or Guillain-Barré syndrome;
phototherapy for psoriasis;
vaccination with BCG (Bacille Calmette-Guérin); or
if you are scheduled to receive any vaccines.
Make sure your child is current on all vaccines before he or she starts treatment with infliximab.
Infliximab may cause a rare type of lymphoma (cancer) of the liver, spleen, and bone marrow that can be fatal. This has occurred mainly in teenagers and young men with Crohn's disease or ulcerative colitis. However, anyone with an inflammatory autoimmune disorder may have a higher risk of lymphoma. Talk with your doctor about your own risk.
Infliximab may cause other types of cancer, such as skin cancer or cancer of the cervix. Ask your doctor about this risk.
If you use infliximab while you are pregnant, make sure any doctor caring for your new baby knows that you used the medicine during pregnancy. Being exposed to infliximab in the womb could affect your baby's vaccination schedule during the first 6 months of life.
You should not breast-feed while you are receiving infliximab.
Infliximab is not for use in children younger than 6 years old.
How is infliximab given?
Before you start treatment with infliximab, your doctor may perform tests to make sure you do not have tuberculosis or other infections.
Infliximab is given as an infusion into a vein. A healthcare provider will give you this injection.
You may be watched closely after receiving infliximab, to make sure the medicine has not caused any serious side effects.
Infliximab affects your immune system. You may get infections more easily, even serious or fatal infections. Your doctor will need to examine you on a regular basis, and you may need frequent TB tests.
If you need surgery, tell the surgeon ahead of time that you are using infliximab.
If you've ever had hepatitis B, using infliximab can cause this virus to become active or get worse. You may need frequent liver function tests while using infliximab and for several months after you stop.
