Xeljanz (tofacitinib) blocks the activity of certain enzymes in the body that affect immune system function.
Xeljanz is used to treat moderate to severe rheumatoid arthritis or active psoriatic arthritis in adults who have tried methotrexate or other medications without successful treatment of symptoms. Tofacitinib is sometimes given in combination with methotrexate or other arthritis medicines.
