Xeljanz XR (tofacitinib extended-release) is a prescription medication that belongs to a class of drugs known as Janus kinase inhibitors (JAK inhibitors). It is used to treat adults with moderate to severe rheumatoid arthritis (RA) who have not responded well to other treatments.

Patients should tell their healthcare provider immediately if they experience any symptoms of infection, such as fever, cough, or persistent flu-like symptoms. Patients should also report any symptoms of liver problems, such as yellowing of the skin or eyes, dark urine, or abdominal pain.
Precautions:
Before taking Xeljanz XR, patients should tell their healthcare provider about all their medical conditions and any medications they are taking, including over-the-counter drugs and herbal supplements.
