Psoriatic Arthritis: For adults with active psoriatic arthritis who didn’t respond well to or couldn’t tolerate TNF blockers.
Ankylosing Spondylitis: For adults with active ankylosing spondylitis who didn’t respond well to or couldn’t tolerate TNF blockers.
Ulcerative Colitis: For adults with moderate to severe ulcerative colitis who didn’t respond well to or couldn’t tolerate TNF blockers.
Polyarticular Course Juvenile Idiopathic Arthritis: For children aged 2 years and older with active polyarticular course juvenile idiopathic arthritis who didn’t respond well to or couldn’t tolerate TNF blockers.
It’s important not to use Tofacitinib Citrate in combination with certain other medications, like biologic DMARDs or strong immunosuppressants such as azathioprine and cyclosporine.
