The FDA approved Xeljanz® and Xeljanz XR® (generically known as tofacitinib) in 2012 to treat rheumatoid arthritis (RA); the FDA later approved for treatment of psoriatic arthritis (PSA), ulcerative colitis (UC) and juvenile idiopathic arthritis (JIA). However, questions about the drug’s safety were raised after an FDA required clinical trial found elevated risks of severe side effects including blood clots, heart problems, cancer and even death.
Currently the 5mg tablet once or twice daily is approved for rheumatoid arthritis, but a 10mg twice daily dose is approved for moderate to severe ulcerative colitis.
The FDA required a boxed warning, the agency’s most prominent warning, for Xeljanz warning of the potential for deadly effects. On Sept. 1, 2021, the FDA announced that it was revising a previous warning and that it includes two additional drugs, Olumiant® and RinvoqTM, which share a mechanism of action with Xeljanz and are also required to include the new boxed warning

Xeljanz, Olumiant, Rinvoq (JAK Inhibitors) side effects
Potential complications of Xeljanz, Olumiant and Rinvoq include:

- Serious heart-related problems, such as a heart attack or stroke
- Cancer, including blood cancers such as lymphoma or lung cancer
Xeljanz boxed warning background
In 2019, interim results of a required post-marketing safety study conducted by Pfizer, Study ID Number A3921133, showed an increased risk of blood clots and death with the higher 10mg twice daily dosage. As a result of this safety study, the FDA approved the addition of boxed warnings for blood clots and death on the drug’s label in July 2019.
The FDA then alerted the public in February 2021 that preliminary results from a safety clinical trial also showed an increase risk of serious heart related problems and cancer compared to another type of medicine. Further studies of the drug’s effects are ongoing.
