Humira® (adalimumab)

Rheumatoid arthritis (RA)is a disease of the immune system. In RA, the immune system attacks the body's own healthy cells, mistaking them for cells that don't belong. This causes inflammation in the lining and connective tissues of the joints. RA may come on suddenly or appear slowly over time. Its symptoms may include pain, swelling, stiffness in the joints, and fatigue associated with the above symptoms.

Psoriatic arthritis is a condition related to the joints characterized by inflammatory arthritis in combination with skin that is dry, scaly, thick and inflamed. While the exact cause of psoriatic arthritis has not been determined, it is believed that certain changes in the immune system are important. The immune system normally protects your body against foreign invaders such as bacteria, fungi and viruses. But with psoriatic arthritis, the immune system loses its ability to tell the difference between these foreign invaders and the body's normal cells and begins to attack the body's cells also. This causes inflammation in the lining and connective tissues of the joints, as well as scaling, redness and inflammation on the skin.

Ankylosing Spondylitis (AS) is a chronic inflammatory disorder that can often be progressive. AS involves pain and inflammation primarily of the spine and sacroiliac joints (area where your spine meets your pelvis).
