What Is Humira?

Humira (adalimumab) is an injectable medication used to treat Crohn's disease, plaque psoriasis, ulcerative colitis, and certain types of arthritis. It also treats uveitis and a skin condition known as hidradenitis suppurativa. Humira is available in prefilled syringes, prefilled pens, and vials.

Adalimumab is a type of monoclonal antibody. It inhibits the activity of tumor necrosis factor (TNF) molecule.

TNF molecules are produced by the immune system and aid in the fight against germs. These molecules cause swelling when your body fights germs. TNF molecules are sometimes produced in excess by the body. Excess molecules cause pain and damage, as well as inflammatory diseases.

Humira binds to and inhibits TNF molecules. Adalimumab reduces swelling and pain by blocking TNF molecules. It alleviates symptoms as well as the damage caused by inflammatory conditions.
