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 can lower blood cells that help your body fight infections. Serious and sometimes fatal infections may occur. Call your doctor right away if you have signs of infection such as 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).
To make sure infliximab is safe for you, tell your doctor if you have:
severe heart failure, or other heart problems;
an active or recent infection, fever, cough, flu symptoms, open sores or skin wounds;
a history of seizures;
a history of cancer;
a weak immune system;
numbness or tingling anywhere in your body;
a disease that affects the nerves or muscles, such as multiple sclerosis or Guillain-Barré syndrome;
if you have recently been vaccinated 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.
Some people using infliximab have developed a rare fast-growing type of lymphoma (cancer). This condition affects the liver, spleen, and bone marrow, and it can be fatal. This has occurred mainly in male teenagers and young men using infliximab with other medicines to treat Crohn's disease or ulcerative colitis.
However, people with autoimmune disorders (including rheumatoid arthritis, Crohn's disease, ankylosing spondylitis, and psoriasis) may have a higher risk of lymphoma. Talk to your doctor about your individual risk.
Using infliximab may increase your risk of developing other types of cancer, including skin cancer. Ask your doctor about your specific risk.
Tell your doctor if you are pregnant or plan to become pregnant. 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.
It is not known whether infliximab passes into breast milk. 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 (TB) or other infections.
Infliximab is injected into a vein through an IV. 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 can lower blood cells that help your body fight infections and help your blood to clot. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Your blood may need to be tested often, and you may need frequent TB tests.
If you need surgery, tell the surgeon ahead of time that you are using infliximab.
If you have ever had hepatitis B, infliximab can cause this condition to come back or get worse. You will need frequent blood tests to check your liver function during treatment and for several months after you stop using this medicine.
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), zoster (shingles), and nasal flu (influenza) vaccine.
Infliximab side effects
Some side effects may occur during the injection. Tell your caregiver right away if you feel dizzy, nauseated, light-headed, itchy or tingly, swollen, short of breath, or have a headache, fever, chills, muscle or joint pain, pain or tightness in your throat, chest pain, or trouble swallowing during the injection. Infusion reactions may also occur within 1 or 2 hours after injection.
Serious and sometimes fatal infections may occur during treatment with infliximab. Call your doctor right away if you have signs of infection such as: fever, extreme tiredness, flu symptoms, cough, or skin symptoms (pain, warmth, or redness).
Call your doctor at once if you have:
skin changes, new growths on the skin;
pale skin, easy bruising or bleeding;
liver problems--upper stomach pain, tiredness, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);

What other drugs will affect infliximab?
