Important Safety Update for XELJANZ® (tofacitinib)

Close

On Friday, December 3, 2021, the U.S. Food and Drug Administration (FDA) updated the XELJANZ full prescribing information. Pfizer issued a media statement announcing that the U.S. full prescribing information for XELJANZ® (tofacitinib) has been updated based on the U.S. FDA’s completed review of the ORAL Surveillance trial, a post-marketing required safety study. Talk to your healthcare provider if you have any questions or concerns about this safety update. Your healthcare provider should consider the benefits and risks of XELJANZ.

The safety information below applies to all marketed formulations of XELJANZ. Specific risks associated with certain dosing are noted.

As a result of this review, an additional warning for Major Cardiovascular Events, and updated warnings for Mortality, Cancer, and Blood Clots were included in the Boxed Warning and related Warnings and Precautions section of the prescribing information and in the Most Important Information I Should Know section of the patient Medication Guide for XELJANZ.

The updated Boxed Warning information regarding Mortality discusses the increased risk of death in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor taking recommended doses of XELJANZ.

The updated Boxed Warning regarding cancer discusses a higher risk of certain cancers, including lymphoma and lung cancer in patients taking XELJANZ, especially if you are a current or past smoker. Tell your healthcare provider if you are a current or past smoker or have had any type of cancer.

The new Boxed Warning includes information regarding increased risk of major cardiovascular events such as heart attack, stroke, or death in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor and are taking recommended doses of XELJANZ, especially if you are a current or past smoker.

Patients taking XELJANZ should seek medical attention right away or get emergency help if you have any symptoms of a heart attack or stroke, including:

  • discomfort in the center of your chest that lasts for more than a few minutes, or that goes away and comes back
  • severe tightness, pain, pressure, or heaviness in your chest, throat, neck, or jaw
  • pain or discomfort in your arms, back, neck, jaw, or stomach
  • shortness of breath with or without chest discomfort
  • breaking out in a cold sweat
  • nausea or vomiting
  • feeling lightheaded
  • weakness in one part or on one side of your body
  • slurred speech

The updated Boxed Warning regarding blood clots in the lungs (pulmonary embolism, PE), veins of the legs (deep vein thrombosis, DVT) and arteries (arterial thrombosis) discusses that blood clots have happened more often in patients who are 50 years of age and older and with at least 1 heart disease (cardiovascular) risk factor taking recommended doses of XELJANZ. Patients should tell their healthcare provider if they have had blood clots in the veins of their legs, arms, or lungs or clots in arteries in the past. Patients should always ask their doctors for medical advice about adverse events. You are encouraged to report adverse events related to Pfizer products by calling 1-800-438-1985 (U.S. only). If you prefer, you may contact the U.S. Food and Drug Administration (FDA) directly. Visit http://www.fda.gov/MedWatch or call 1-800-FDA-1088.

The FDA approved use of XELJANZ for adults with moderately to severely active rheumatoid arthritis, active psoriatic arthritis, and for children age 2 and over with polyarticular course juvenile idiopathic arthritis and now recommends use after one or more medicines called tumor necrosis factor (TNF) blockers did not work well or cannot be tolerated.

If you have any questions about these updates talk to your healthcare provider.

The updated Important Safety Information and Indications for XELJANZ are included below for your review.

It is also important to read the patient Medication Guide you receive with your XELJANZ prescriptions, which explains the important things you need to know about the medicine. These include side effects, what the medicine is used for, how to take and store it properly, and other things to watch for when you’re taking the medicine.

Information about Post-Marketing Safety Study

When the FDA first approved XELJANZ for adults with moderate to severe rheumatoid arthritis in 2012, the agency required a clinical safety trial to examine the risk for heart-related problems, cancer, and serious infections in XELJANZ compared to another type of medicine called tumor necrosis factor (TNF) blockers. This trial, known as Oral Surveillance enrolled 4,369 participants who were required to be at least 50 years of age and have at least one cardiovascular risk factor.

IMPORTANT SAFETY INFORMATION

The safety information below applies to all marketed formulations of XELJANZ. Specific risks associated with certain dosing are noted.

Serious infections. XELJANZ can lower the ability of your immune system to fight infections. Do not start taking XELJANZ if you have any kind of infection unless your healthcare provider tells you it is okay. Serious infections have happened in people taking XELJANZ. These serious infections include tuberculosis (TB) and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections. Your healthcare provider should test you for TB before starting and during treatment with XELJANZ. You should not start taking XELJANZ if you have any kind of infection unless your healthcare professional tells you it is okay.

Before and after starting XELJANZ, tell your doctor if you have an infection or symptoms of an infection, including:

  • fever, sweating, or chills
  • cough
  • blood in phlegm
  • warm, red, or painful skin or sores on your body
  • burning when you urinate
  • urinating more often than normal
  • muscle aches
  • shortness of breath
  • weight loss
  • diarrhea or stomach pain
  • feeling very tired

Increased risk of death in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor and are taking XELJANZ 5 mg twice daily or XELJANZ 10 mg twice daily.

Cancer. XELJANZ may increase your risk of certain cancers by changing the way your immune system works. Lymphoma and other cancers, including skin cancers, can happen. People taking XELJANZ 5 mg twice daily or XELJANZ 10 mg twice daily have a higher risk of certain cancers including lymphoma and lung cancer, especially if you are a current or past smoker. Tell your healthcare provider if you have ever had any type of cancer.

Higher dose. People with ulcerative colitis taking the higher dose of XELJANZ (10 mg twice daily) or XELJANZ XR (22 mg one time each day) have a higher risk of serious infections, shingles, or skin cancers.

Immune system problem. Some people who have taken XELJANZ with certain other medicines to prevent kidney transplant rejection have had a problem with certain white blood cells growing out of control (Epstein Barr Virus–associated post-transplant lymphoproliferative disorder).

Increased risk of major cardiovascular events such as heart attack, stroke or death in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor and are taking XELJANZ 5 mg twice daily or XELJANZ 10 mg twice daily, especially if you are a current or past smoker.

Get emergency help right away if you have any symptoms of a heart attack or stroke while taking XELJANZ, including:

  • discomfort in the center of your chest that lasts for more than a few minutes, or that goes away and comes back
  • severe tightness, pain, pressure, or heaviness in your chest, throat, neck, or jaw
  • pain or discomfort in your arms, back, neck, jaw, or stomach
  • shortness of breath with or without chest discomfort
  • breaking out in a cold sweat
  • nausea or vomiting
  • feeling lightheaded
  • weakness in one part or on one side of your body
  • slurred speech

Blood clots in the lungs (pulmonary embolism, PE), veins of the legs (deep vein thrombosis, DVT), and arteries (arterial thrombosis) have happened more often in patients who are 50 years of age and older and with at least 1 heart disease (cardiovascular) risk factor taking XELJANZ 5 mg twice daily or XELJANZ 10 mg twice daily. Blood clots in the lungs have also happened in patients with ulcerative colitis. Some people have died from these blood clots.

  • Stop taking XELJANZ and tell your healthcare provider right away if you have any signs and symptoms of blood clots such as sudden shortness of breath, difficulty breathing, chest pain, swelling of a leg or arm, leg pain or tenderness, or red or discolored skin in the leg or arm.

Tears (perforation) in the stomach or intestines. Tell your healthcare provider if you have had diverticulitis (inflammation in parts of the large intestine) or ulcers in your stomach or intestines. Some people taking XELJANZ can get tears in their stomach or intestine. This happens most often in people who also take nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or methotrexate. Tell your healthcare provider right away if you have fever, stomach-area pain that does not go away, and a change in your bowel habits.

Serious allergic reactions can occur. Stop using XELJANZ and call your healthcare provider right away if you have swelling of your lips, tongue, throat, or get hives.

Changes in certain lab test results. Your doctor should do blood tests to check your white and red blood cells before and while you are taking XELJANZ. Your doctor should also check certain liver tests. You should not receive XELJANZ if your lymphocyte count, neutrophil count, or red blood cell count is too low or your liver function test levels are too high. Changes in lab test results may cause your healthcare provider to stop your XELJANZ treatment for a time. Your cholesterol levels should be checked 4 to 8 weeks after you start receiving XELJANZ.

Before you use XELJANZ, tell your healthcare provider if you:

  • Are being treated for an infection, have an infection that won’t go away or keeps coming back, or think you have symptoms of an infection
  • Have TB, or have been in close contact with someone with TB, or were born in, lived in, or traveled where there is more risk for getting TB
  • Have diabetes, chronic lung disease, HIV, or a weak immune system. People with these conditions have a higher chance for infections
  • Live or have lived in certain areas (such as Ohio and Mississippi River Valleys and the Southwest) where there is an increased chance for getting certain kinds of fungal infections
  • Have or have had Hepatitis B or C
  • Are a current or past smoker

  • Are pregnant, planning to become pregnant, breastfeeding, or planning to breastfeed. You should not take XELJANZ and breastfeed
  • Have had a reaction to tofacitinib or any of the ingredients
  • Are taking other medicines, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Especially tell your healthcare provider if you take any of the following medicines while taking XELJANZ since this may increase your risk of infection:
    • tocilizumab (Actemra®)
    • etanercept (Enbrel®)
    • adalimumab (Humira®)

    • azathioprine, cyclosporine, or other immunosuppressive drugs
  • Tell your healthcare provider if you are taking medicines that affect the way certain liver enzymes work. Ask your healthcare provider if you are not sure if your medicine is one of these.

What are other possible side effects of XELJANZ/XELJANZ XR?

If you are a carrier of the Hepatitis B or C virus (viruses that affect the liver), the virus may become active while you use XELJANZ. Your healthcare provider may do blood tests before starting and while using treatment with XELJANZ.

Important Safety InformationISI Modal

The safety information below applies to all marketed formulations of XELJANZ. Specific risks associated with certain dosing are noted.

Serious infections. XELJANZ can lower the ability of your immune system to fight infections. Do not start taking XELJANZ if you have any kind of infection unless your healthcare provider tells you it is okay. Serious infections have happened in people taking XELJANZ. These serious infections include tuberculosis (TB) and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections. Your healthcare provider should test you for TB before starting and during treatment with XELJANZ. You should not start taking XELJANZ if you have any kind of infection unless your healthcare professional tells you it is okay.

Before and after starting XELJANZ, tell your doctor if you have an infection or symptoms of an infection, including:

  • fever, sweating, or chills
  • cough
  • blood in phlegm
  • warm, red, or painful skin or sores on your body
  • burning when you urinate
  • urinating more often than normal
  • muscle aches
  • shortness of breath
  • weight loss
  • diarrhea or stomach pain
  • feeling very tired

Increased risk of death in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor and are taking XELJANZ 5 mg twice daily or XELJANZ 10 mg twice daily.

Cancer. XELJANZ may increase your risk of certain cancers by changing the way your immune system works. Lymphoma and other cancers, including skin cancers, can happen. People taking XELJANZ 5 mg twice daily or XELJANZ 10 mg twice daily have a higher risk of certain cancers including lymphoma and lung cancer, especially if you are a current or past smoker. Tell your healthcare provider if you have ever had any type of cancer.

Higher dose. People with ulcerative colitis taking the higher dose of XELJANZ (10 mg twice daily) or XELJANZ XR (22 mg one time each day) have a higher risk of serious infections, shingles, or skin cancers.

Immune system problem. Some people who have taken XELJANZ with certain other medicines to prevent kidney transplant rejection have had a problem with certain white blood cells growing out of control (Epstein Barr Virus–associated post-transplant lymphoproliferative disorder).

Increased risk of major cardiovascular events such as heart attack, stroke or death in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor and are taking XELJANZ 5 mg twice daily or XELJANZ 10 mg twice daily, especially if you are a current or past smoker.

Get emergency help right away if you have any symptoms of a heart attack or stroke while taking XELJANZ, including:

  • discomfort in the center of your chest that lasts for more than a few minutes, or that goes away and comes back
  • severe tightness, pain, pressure, or heaviness in your chest, throat, neck, or jaw
  • pain or discomfort in your arms, back, neck, jaw, or stomach
  • shortness of breath with or without chest discomfort
  • breaking out in a cold sweat
  • nausea or vomiting
  • feeling lightheaded
  • weakness in one part or on one side of your body
  • slurred speech

Blood clots in the lungs (pulmonary embolism, PE), veins of the legs (deep vein thrombosis, DVT), and arteries (arterial thrombosis) have happened more often in patients who are 50 years of age and older and with at least 1 heart disease (cardiovascular) risk factor taking XELJANZ 5 mg twice daily or XELJANZ 10 mg twice daily. Blood clots in the lungs have also happened in patients with ulcerative colitis. Some people have died from these blood clots.

  • Stop taking XELJANZ and tell your healthcare provider right away if you have any signs and symptoms of blood clots such as sudden shortness of breath, difficulty breathing, chest pain, swelling of a leg or arm, leg pain or tenderness, or red or discolored skin in the leg or arm.

Tears (perforation) in the stomach or intestines. Tell your healthcare provider if you have had diverticulitis (inflammation in parts of the large intestine) or ulcers in your stomach or intestines. Some people taking XELJANZ can get tears in their stomach or intestine. This happens most often in people who also take nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or methotrexate. Tell your healthcare provider right away if you have fever, stomach-area pain that does not go away, and a change in your bowel habits.

Serious allergic reactions can occur. Stop using XELJANZ and call your healthcare provider right away if you have swelling of your lips, tongue, throat, or get hives.

Changes in certain lab test results. Your doctor should do blood tests to check your white and red blood cells before and while you are taking XELJANZ. Your doctor should also check certain liver tests. You should not receive XELJANZ if your lymphocyte count, neutrophil count, or red blood cell count is too low or your liver function test levels are too high. Changes in lab test results may cause your healthcare provider to stop your XELJANZ treatment for a time. Your cholesterol levels should be checked 4 to 8 weeks after you start receiving XELJANZ.

Before you use XELJANZ, tell your healthcare provider if you:

  • Are being treated for an infection, have an infection that won’t go away or keeps coming back, or think you have symptoms of an infection
  • Have TB, or have been in close contact with someone with TB, or were born in, lived in, or traveled where there is more risk for getting TB
  • Have diabetes, chronic lung disease, HIV, or a weak immune system. People with these conditions have a higher chance for infections
