• Limitations of Use: Use of Tofacitinib (XELJANZ®/XELJANZ® XR) in combination with biologic DMARDs or with potent immunosuppressants such as azathioprine and cyclosporine is not recommended.
Ulcerative Colitis
Tofacitinib (XELJANZ®/XELJANZ® XR) is indicated for the treatment of adult patients with moderately to severely active ulcerative colitis (UC).
• Limitations of Use: Use of Tofacitinib (XELJANZ®/XELJANZ® XR) in combination with biological therapies for UC or with potent immunosuppressants such as azathioprine and cyclosporine is not recommended.
Dosage
Administration Instructions
Do not initiate Tofacitinib (XELJANZ®/XELJANZ® XR) if absolute lymphocyte count <500 cells/mm³, an absolute neutrophil count (ANC) <1000 cells/mm³ or hemoglobin <9 g/dL.
Recommended Dosage
Rheumatoid Arthritis
• Tofacitinib (XELJANZ®) 5 mg twice daily or XELJANZ XR 11 mg once daily.
• Recommended dosage in patients with moderate and severe renal impairment or moderate hepatic impairment is Tofacitinib (XELJANZ®) 5 mg once daily.
Psoriatic Arthritis (in combination with nonbiologic DMARDs)
• Tofacitinib (XELJANZ®) 5 mg twice daily or XELJANZ® XR 11 mg once daily.
