On the market since 2012, Xeljanz is meant to help relieve the pain and inflammation for patients who suffer from certain types of arthritis or ulcerative colitis. However, in post-marketing studies, the FDA found the drug to seriously increase the risk of blood clots in some patients – a side effect that was never disclosed to users.

What Is Xeljanz and How Does It Work?

Xeljanz (whose clinical name is tofacitinib) is produced and marketed by Pfizer to treat rheumatoid arthritis (RA) since 2012, psoriatic arthritis (PA) since 2013, and ulcerative colitis (UC) since 2018. These conditions are called autoimmune disorders and result from attacks by the body’s own immune system. Xeljanz works by suppressing the immune system to relieve symptoms.

According to the Xeljanz website, approximately 132,000 Americans were prescribed the drug between 2013 and 2018 to treat RA. Many more were prescribed it to treat UC or PA.

Xeljanz is a JAK (Janus kinase enzyme) inhibitor. It is only supposed to be prescribed:

  • To RA sufferers who did not respond well to methotrexate treatment, which works to relieve symptoms differently than Xeljanz
  • To PA sufferers when disease-modifying antirheumatic drugs (DMARDs) fail
  • To people with ulcerative colitis, Xeljanz is only to be used if tumor necrosis factor inhibitors (TNFis) fail.

What Are the Side Effects of Xeljanz, and Why Are We Just Now Learning About Risks?

The list of side effects has grown since Xeljanz was first approved for use by the FDA in 2012. It began with a long list of possible side effects, primarily:

  • upper respiratory tract infection
  • cold-like symptoms
  • vomiting
  • diarrhea
  • rash
  • herpes zoster infection (shingles)
  • headache

The drug also may have some more severe side effects. Several of these have resulted in so-called “black box” warnings. This refers to how the FDA mandates the display of a drug’s most severe or life-threatening side effects. It is the most serious warning required by the FDA.

Xeljanz already had black box warnings due to the risks of severe infections and cancer. Having those warnings allowed physicians and patients to weigh the risk of using the drug against the possible consequences of using it. However, according to post-marketing studies, there was another life-threatening side effect that was not disclosed.

NOTE: The FDA approves drugs based on clinical trials but often requires post-marketing studies to be conducted. You can learn more about the FDA’s post-marketing requirements.

Why Are Xeljanz Users Suing?

When a drug has a side effect that is not disclosed, it is unfair to patients. Health care decisions should be made with complete information, and when a critical piece is missing, the choice could lead to devastating consequences that would not have happened if the patient or the physician had only known.

When it was introduced in 2012, a year-long prescription of Xeljanz cost approximately $25,000, and the drug had projected annual sales of around $2.5 billion. In 2014, Pfizer presented seven abstracts touting the safety of Xeljanz to the European League Against Rheumatism (EULAR) at the body’s annual meeting. It was estimated that Pfizer would report 2020 sales of Xeljanz of $2.4 billion and that the product will peak at just $2.8 billion in 2025 before losing patent protection in 2026.

The FDA eventually approved the 10mg dosage of Xeljanz for use in UC patients. The smaller 5mg was approved for RA and PA sufferers due to the possibility of increased risk for serious side effects. The belief may have been that the 5mg dose did not pose an added risk.

Hidden Threats of Xeljanz Emerge

During the post-marketing study by ORAL Surveillance, whose results were published in 2019, Pfizer had to modify the test protocols mid-study due to correlations between the 10mg doses of Xeljanz and increased risk of thrombosis and death.

Thrombosis: when a blood clot has formed in a vessel, impeding blood flow.

Even though there were no immediate signals that the 5mg dosage posed a threat, in 2020, key opinion leaders opted for caution and limited use of Xeljanz in RA patients with cardiovascular risk factors. The move proved to be prescient. The data from the study indicates that the risk of major adverse cardiac events was similar regardless of dosage. The study was conducted to show that Xeljanz was “non-inferior” to another treatment, and both the 10mg dosage and the 5mg dosage failed to reach the trial’s primary endpoints.

”Unfortunately, now that the trial has concluded and preliminary results are available, both the 5mg twice daily and 10 mg twice daily dose of tofacitinib have demonstrably higher risks of cardiovascular and cancer-related events, and the risk was dose-related,” said C. Michael White, PharmD, FCP, FCCP, the department head and a distinguished professor of pharmacy practice in the Department of Pharmacy Practice at the University of Connecticut, in an article in Clinical Oncology.

The cardiac events involved clotting, specifically deep vein thrombosis (DVT), and the risk of pulmonary embolisms. The FDA reacted to the study’s results by ordering another “black box“ warning to be placed on the drug.

Deep Vein Thrombosis Due to Xeljanz Use?

Deep Vein Thrombosis (DVT): when a blood clot forms in a vein deep inside the body.

Patients who have been taking Xeljanz, regardless of dosage, should be on the lookout for the symptoms of DVT. It is a life-threatening condition. Consult your physician immediately if you are experiencing any of the following:

  • swelling in extremities (feet, hands, arms, legs), usually only on one side
  • cramping pain in your leg that generally begins in your calf
  • pain that moves from your arm to your forearm
  • severe, unexplained pain in your foot and ankle
  • an area of skin that feels warmer than the surrounding skin
  • skin in an area turning pale, or a reddish or bluish color
  • neck or shoulder pain
  • weakness in your hand

Pulmonary Embolism Due to Xeljanz Use?

Pulmonary embolism: when a blood clot travels to the lungs. It can be caused by DVT.

Another serious cardiovascular problem that the 2019 study linked to Xeljanz is the risk of pulmonary embolism (PE). This is a clot-related risk, and anyone suffering from DVT is at an increased risk of PE. The dangers are many. Multiple clots may be involved, and the part of the lung that experiences blockage may die (known as pulmonary infarction). Regardless, the condition makes it hard for your lungs to supply your body with oxygen.

Seek medical help immediately if you are experiencing any symptoms of PE, including:

  • shortness of breath that appears suddenly and gets worse with exertion
  • sharp chest pain that occurs when you try to breathe deeply, cough, or bend
  • coughing, especially when blood is produced
  • rapid or arrhythmic heartbeat
  • lightheadedness/dizziness
  • sweating excessively/fever
  • leg pain or swelling
  • discolored skin (cyanosis) or temperature irregularities in the skin

Was Xeljanz Recalled By the FDA?

No. The result of the post-marketing clinical study was the revelation of a severe health risk that was previously undisclosed. Instead of recalling the drug, the FDA applied additional warnings to its label.

“While the increased risks of blood clots and of death were seen in patients taking [the 10 mg twice daily] dose for rheumatoid arthritis, these risks may also apply to those taking Xeljanz for ulcerative colitis.” –U.S. Food and Drug Administration

This does not mean the drug is safe for all users. In fact, the FDA’s new warning indicates that some people who are taking Xeljanz are at risk for possibly life-threatening side effects of which they were never told!

What Should I Do if I Am Taking Xeljanz?


The FDA has stated that those currently taking Xeljanz should not discontinue using it without consulting their physicians, as doing so could make things worse. Talk to your doctor as soon as you can. As always, if you are experiencing symptoms of a life-threatening condition, seek immediate medical attention!

Who Should I Call Regarding My Xeljanz Use?


Your first call should be to the physician that prescribed you Xeljanz. He or she may wish to examine you for any trace of these now-public side effects of using the drug.

If you have already suffered a major adverse cardiac event or are suffering from the symptoms of DVT or PE, contact an attorney with experience handling dangerous drug cases.
