What is Xeljanz?

Learn about Xeljanz Lawsuits

Xeljanz, which was developed and manufactured by the pharmaceutical company Pfizer, is used to treat certain serious, chronic, and progressive inflammatory conditions. It was approved by the Food and Drug Administration (FDA) in 2012 to treat rheumatoid arthritis (RA), psoriatic arthritis, ulcerative colitis, and polyarticular course juvenile idiopathic arthritis. Xeljanz works by decreasing the immune system’s activity, as an overactive immune system contributes to the conditions listed above.

FDA Safety Communication

In 2019, the FDA issued a drug safety communication after interim results from a safety trial found an increased risk of serious heart-related problems and cancer associated with Xeljanz. The trial studied two doses of the drug – 5 mg twice daily (the approved dose for RA) and 10 mg twice daily – comparing it to another RA drug called a TNF inhibitor. The interim results showed an increased risk of blood clots and death associated with the 10 mg dose, and accordingly, the FDA approved a Boxed Warning to the Xeljanz prescribing information.

Final Trial Results

The FDA’s review of the final trial results found an increased rate of serious heart-related complications, including heart attack and stroke, cancer, blood clots and death in patients treated with both doses of Xeljanz. The FDA advises anyone taking Xeljanz to talk to your health care professionals if you have any questions or concerns and to seek medical attention immediately if you are experiencing symptoms of a blood clot or other unusual symptoms.
