What is infliximab?
Infliximab is also used to treat ulcerative colitis or Crohn's disease in adults and children at least 6 years old.
Infliximab is often used when other medicines have not been effective.

Infusion reactions may also occur within 1 or 2 hours after injection.

What is the most important information I should know about infliximab?
Infliximab affects your immune system. You may get infections more easily, even serious or fatal infections. Before you start using infliximab, your doctor may perform tests to make sure you do not have certain infections.
Call your doctor if you have a fever, tiredness, flu symptoms, cough, or skin sores.
What should I discuss with my healthcare provider before receiving infliximab?
You should not be treated with infliximab if you are allergic to it.
Tell your doctor if you have ever had tuberculosis (TB) or if anyone in your household has tuberculosis. Also tell your doctor if you have recently traveled. Tuberculosis and some fungal infections are more common in certain parts of the world, and you may have been exposed during travel.
Tell your doctor if you have ever had:
- an active infection (fever, cough, flu symptoms, open sores or skin wounds);
- heart failure or other heart problems;
- a weak immune system;
- liver failure, hepatitis B, or other liver problems;
- chronic obstructive pulmonary disease (COPD);
- heart problems;
- 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.
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 breastfeed 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.
This medicine must be given slowly, and the infusion can take at least 2 hours to complete.
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.
Serious infections may be more likely in older adults.
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 this medicine and for several months after you stop.
What happens if I miss a dose?
Call your doctor for instructions if you miss an appointment for your infliximab injection.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while receiving infliximab?
Avoid activities that may increase your risk of bleeding injury.
Do not receive a "live" vaccine while using infliximab, or you could develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), and zoster (shingles).
What other drugs will affect infliximab?
Tell your doctor about all your other medicines, especially:
- any "biologic" medications to treat your condition--adalimumab, certolizumab, etanercept, golimumab, natalizumab, rituximab, and others; or
- any other medicines to treat Crohn's disease, ulcerative colitis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, or psoriasis.
This list is not complete. Other drugs may affect infliximab, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
