If you have rheumatoid arthritis, your healthcare provider may recommend a medication called tofacitinib. This prescription medicine works by blocking the actions of certain enzymes that regulate immune cell function. It comes as a tablet that is taken once or twice a day. Most people taking this drug will develop some type of side effect, such as infections, headaches, or diarrhea.
Tofacitinib (Xeljanz®) is a prescription medication approved for treating rheumatoid arthritis (RA). It is a "biologic" RA treatment. Unlike many other newer RA medications, tofacitinib is taken by mouth rather than injected. It belongs to a class of medicines known as kinase inhibitors.
