Tofacitinib is a JAK inhibitor. It’s used to treat stuff like rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis. It’s a pill you take.
It’s supposed to help keep your immune system in check, so it doesn’t cause autoimmune diseases to get worse. You can get it in two doses: 5 mg and 10 mg. They’re both these tablets with a coating.
Most people take 5 mg twice a day. The pills come in bottles with 60 tablets in each one. How it works is, it blocks these JAK enzymes.
They’re big players in setting off inflammation in autoimmune diseases.
