What is the most important information I should know about adalimumab (Humira)?

Some people using adalimumab 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 teenagers and young adults using adalimumab or similar medicines to treat Crohn's disease or ulcerative colitis.

Call your doctor at once if you have any of the following symptoms: fever, night sweats, itching, loss of appetite, weight loss, tiredness, feeling full after eating only a small amount, pain in your upper stomach that may spread to your shoulder, nausea, easy bruising or bleeding, pale skin, feeling light-headed, rapid heart rate, dark urine, clay-colored stools, or jaundice (yellowing of the skin or eyes).

Adalimumab can lower blood cells that help your body fight infections and help your blood to clot. Your blood may need to be tested often. Avoid being near people who are sick or have infections. Avoid activities that may increase your risk of bleeding injury. Serious and sometimes fatal infections may occur during treatment with adalimumab. Tell your doctor at once if you develop signs of infection.

Do not receive a "live" vaccine while you are being treated with adalimumab.
