MS, RNAJN The American Journal of Nursing: March 2013 - Volume 113 - Issue 3 - p 22,23 doi: 10.1097/01.NAJ.0000427871.05603.e4 Drug Watch Abstract Author Information Tofacitinib (Xeljanz) has been approved to treat moderate-to-severe rheumatoid arthritis in adults who've had an inadequate response to or cannot tolerate methotrexate. The drug can produce serious, even life-threatening, infections. The most common serious infections reported include pneumonia, cellulitis, herpes zoster, and urinary tract infection. Tuberculosis and other opportunistic infections are also possible. Tofacitinib can decrease various cell counts, and blood counts need to be assessed carefully before and during therapy. Diane S.
