  9. Humira (adalimumab) • in October 2005 by the U.S. FDA for the treatment of psoriatic arthritis. It is also approved for treating rheumatoid arthritis • blocks tumor necrosis factor-alpha (TNFalpha), • Patients give themselves an injection under the skin every other week • Patients should be screened for latent (hidden) tuberculosis (TB) before taking Humira
