Xeljanz, also known as tofacitinib, is a medication that modulates the immune system by inhibiting Janus kinase (JAK) enzymes. This action helps reduce inflammation and is used to treat autoimmune conditions like rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis. By targeting specific pathways in the immune response, Xeljanz can alleviate symptoms such as joint pain and swelling, but it may also increase the risk of infections and other side effects due to its immune-suppressing effects.
