What is Humira?

Humira is a tumor necrosis factor (TNF) blocker that reduces the effects of a substance in the body that can cause inflammation.

Humira is used to treat many inflammatory conditions in adults, such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, plaque psoriasis, and a skin condition called hidradenitis suppurativa.

Humira is also used in adults and children to treat Crohn's disease, juvenile idiopathic arthritis, ulcerative colitis and uveitis.

Warnings

Humira affects your immune system. Adalimumab can lower the ability of your immune system to fight infections and you may get infections more easily. Serious infections caused by viruses, fungi or bacteria have happened in people taking this medicine. Some people have died from these infections.

Serious infections include tuberculosis (TB). Your doctor should test you for TB before starting and during treatment with Humira.

Before or during treatment with Humira, tell your doctor if you have signs of infection such as fever, chills, aches, tiredness, cough, skin sores, diarrhea, or burning when you urinate.

Before taking this medicine

You should not use Humira if you are allergic to adalimumab.

Before you start using this medicine , tell your doctor if you have signs of infection--fever, chills, sweats, muscle aches, tiredness, cough, bloody mucus, skin sores, diarrhea, burning when you urinate, or feeling constantly tired.

Humira should not be given to a child younger than 2 years old (or 6 years old if treating Crohn's disease). Children using this medicine should be current on all childhood immunizations before starting treatment.

Tell your doctor if you have ever had:

• tuberculosis (or if anyone in your household has tuberculosis);

• a chronic infection;

• cancer;

• hepatitis B (adalimumab can cause hepatitis B to come back or get worse);

• diabetes;

• heart failure;

• any numbness or tingling, or a nerve-muscle disorder such as multiple sclerosis or Guillain-Barre syndrome;

• an allergy to latex rubber;

• if you are scheduled to have major surgery; or

• if you have recently received or are scheduled to receive any vaccine.

Tell your doctor where you live and if you have recently traveled or plan to travel. You may be exposed to infections that are common to certain areas of the world.

Humira 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.

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant. Make sure any doctor caring for your newborn baby knows if you used adalimumab while you were pregnant.

It may not be safe to breastfeed a baby while you are using this medicine. Ask your doctor about any risks.
