What Is Xeljanz?
Xeljanz is a prescription medication approved by the FDA to treat RA and psoriatic arthritis.
The following conditions may be treated with Xeljanz:
- Severe rheumatoid arthritis
- Moderate to severe polyarticular juvenile idiopathic arthritis (PJIA)
- Axial spondyloarthritis without radiographic evidence of AS
- Psoriatic arthritis (PsA)
- Compromised immune system
- Chronic inflammatory conditions
- Arthritis and ulcerative colitis (UC)
Xeljanz is only available in oral capsules of 5 mg or 10 mg twice daily dose. The administration schedule is twice per day for all indications, requiring patients to take two pills twice daily.
Patients with moderate hepatic impairment should only be given the 5mg dose. Patients with severe hepatic impairment should not be given this medication. The safety and efficacy have not been established in patients with severe or end-stage renal disease (ESRD).
Is Xeljanz FDA Approved?
Xeljanz was approved by the FDA (US Food and Drug Administration) on November 25, 2012. The Administration approved the drug after a safety trial result showed that it was more effective than the placebo at treating RA.
However, in September 2021, the FDA reissued Xeljanz’s warning label to include warnings of an increased risk of certain heart-related problems, PE (pulmonary embolism), cancer, and other health-related problems.
Why Xeljanz Is a Dangerous Drug
According to the FDA (Food and Drug Administration), patients taking this drug are at an increased risk for developing:
- Certain types of cancers (malignancies)
- Non-melanoma skin cancer
- Serious heart related problems
- Solid tumors in the liver, lung, or other organs
- Pulmonary embolism lungs (blood clots in the lungs)
- Deep vein thrombosis (blood clots in the legs, pelvis, arms, or head)
These types of diseases may lead to death.
Patients hospitalized due to cardiovascular events were at a 21 percent increased risk. In addition, those who suffered from serious cardiac events had an 82 percent higher chance of dying than those not taking Xeljanz.
The FDA requires additional post-marketing studies to investigate further the risks associated with Xeljanz use. For example, this drug may increase a patient’s risk of developing certain cancer or other life-threatening conditions.
Risk Evaluation and Mitigation Strategy (REMS)
The FDA’s Risk Evaluation and Mitigation Strategy (REMS) called for implementing a Medication Guide to be provided to all patients taking this medication.
In addition, the organization required Pfizer, Inc (Pfizer), the manufacturer of Xeljanz, and EMA-USA (European Medicines Agency), to add new warnings to the drug label regarding malignancies and other serious adverse events.
Xeljanz and Blood Clots, Deep Vein Thrombosis, and Death
According to the CDC (Centers for Disease Control and Prevention) taking Xeljanz increases the risk of blood clots and cardiovascular events in rheumatoid arthritis patients.
This life-threatening condition requires immediate medical attention if a patient exhibits any symptoms associated with pulmonary embolism, deep vein thrombosis (DVT), or stroke.
The following side effects have been reported by people taking Xeljanz:
- Upper respiratory tract infections
- Back pain
- Urinary tract infections
- Sinus infections
Xeljanz may be used to treat RA in addition to psoriatic arthritis. However, the FDA has stated that all patients should use this medication under the guidance of a qualified healthcare provider who will consider any underlying risk factors, such as a history of malignancies, heart disease, pulmonary embolisms, or blood clotting disorders.
Xeljanz: FDA Black Box Warning
In February 2019, the FDA published a drug safety communication about the product’s black box warning. Pfizer said it was revising dosage recommendations for patients treated with the medication.
The FDA has mandated Pfizer, Inc. (Pfizer), the manufacturer of Xeljanz, to add a new warning label to its medication guide due to evidence showing that this prescription may cause cancer.
Thousands of patients have filed lawsuits against the pharmaceutical giant. These Xeljanz claims reveal that the company failed to warn about serious side effects associated with Xeljanz, including heart attack, stroke, and malignancies.
FDA Requires Pfizer to Add Black Box Warning for Xeljanz Following Severe Side Effects
The FDA has mandated Pfizer, Inc. to add a black box warning for cardiovascular events. Pfizer, Inc responded to the FDA’s drug safety communication warning by conducting the Xeljanz Cardiovascular Outcomes Investigation study.
The FDA has also mandated Pfizer, Inc. to update the drug label for this medication regarding the risk of malignancies and other serious adverse events. In addition, the organization stated that it is unclear whether taking Xeljanz increases patients’ chances of developing cancer in addition to cardiovascular diseases.
Pfizer, Inc. has decided to conduct additional clinical studies to fully assess the risk of developing malignancies while taking this medication. The FDA will continue to monitor Xeljanz’s safety profile for further changes and updates.
Cases of Cancers Associated with Xeljanz
Xeljanz has been associated with various cases of cancer and malignancies, including:
- Bladder cancer
- Lung cancer, and other metastatic conditions
These cancers were reported after patients had taken this medication and experienced gastrointestinal and urologic events. Squamous cell carcinoma (SCC) is a type of skin cancer that begins in squamous cells, the flat cells lining the moist surfaces of the body.
Cancer occurs when these cells divide uncontrollably and spread into surrounding tissues. A malignant tumor may also occur when cancerous cells invade and damage tissue and organs nearby.
Symptoms of Cancer-Associated with Xeljanz
Symptoms of cancer associated with taking this medication include:
- Bleeding or discharge from any place on the body
- Weight loss with no known reason
- Coughing up blood or rust-colored sputum
- Dizziness or lightheadedness when getting up suddenly from a lying position
- Nausea or vomiting
- Joint pain or stiffness that does not improve with treatment
- Swelling of the feet, legs, ankles, or hands
- Redness on skin that does not sunburn easily and appears pale in color
- Swelling of the face, eyes, lips, tongue, throat, arms, and legs
- Skin rash that spreads and causes blisters or peeling
- Changes in vision, including blurry vision, seeing double, or trouble telling the difference between blue and green
- Increased risk of blood clots
- Itching, scaling, redness, pain, or sores on the skin
- Chest discomfort or pain radiating to one or both arms
- Severe burning while urinating and frequent urination
- Shortness of breath, coughing and feeling an odd sensation in the chest
- Pain or discomfort in hips, shoulders, ribs, arms, upper back, or neck that may radiate into the jaw or shoulder
- Painful sores inside your mouth or on your lips may be caused by a condition called aphthous stomatitis
This list is not a complete list of side effects associated with taking Xeljanz.
Please note that this medication may increase the risk of serious infections and other conditions that can lead to death. This condition is especially severe if taken by patients who have been diagnosed with cancer or have been weakened by cancer treatments.
Increased Risk of Other Cancers Associated with Xeljanz
Patients who take this medication for severely active rheumatoid arthritis may also be at increased risk for developing other cancers, including:
- Skin cancer
- Lung cancer
- Pancreatic cancer
- Small intestine cancer
- Stomach cancer
While the FDA has not determined that Xeljanz directly causes cancers, the agency has placed this medication under added monitoring for this serious side effect.
Allergic Reactions Associated with Xeljanz
The most common side effects of taking this medication are mild or moderate. They include:
- General swelling
- Upper respiratory tract infection (such as the common cold)
These side effects are often transient, with symptoms disappearing after a few days.
The most serious side effects that may occur are severe, including:
- Asthma attack
- Severe allergic reaction
- Deadly blood clots
- Rash with fever, swollen glands, or flu symptoms
- Inflammatory bowel disease
Exacerbation of Disease with Xeljanz
Medications like Xeljanz have been associated with the exacerbation of disease in some patients.
In clinical trials, a group of 474 RA patients taking 10 mg of Xeljanz twice a day experienced an increased rate of disease flare compared with patients taking a placebo.
There were also reported Xeljanz lawsuit claims where health conditions worsened in patients taking 5 mg to 10 mg daily and those who took 1 mg or 2.5 mg twice daily. For example, some patients experienced increased risks of serious heart-related problems, deep vein thrombosis (DVT), lung cancer, and blood clot health issues.
Psoriatic Arthritis, Ulcerative Colitis, and Xeljanz
The medications are also used to treat people with active psoriatic arthritis, in which methotrexate or other similar medicines did not work well, and adults with moderately to severely active ulcerative colitis.
The FDA and the manufacturer have known serious blood clots and death could occur when taking ulcerative colitis medicines Xeljanz and Tofacitinib Citrate (Generic Xeljanz). However, severe problems have also been associated with other similar drugs.
The Cardiovascular Risk Factor for Rheumatoid Arthritis Patients
Xeljanz is one of the only medications, along with other disease-modifying antirheumatic drugs (DMARDs), approved for treating RA.
Medications that treat rheumatoid arthritis, including Xeljanz, can be associated with serious side effects. These risks include anemia, blood disorders, infection, liver problems, and cancer.
In addition to the risk of developing blood clots from taking methotrexate, there is a higher risk that patients with RA will develop cardiovascular disease.
According to one study, these patients have an increased prevalence of hypertension, obesity, impaired glucose tolerance, or diabetes mellitus compared to healthy controls. The study also found that RA patients are less likely to engage in physical activity or meet federal guidelines for physical activity.
The FDA Ordered Label Changes
The FDA required a few changes to the drug’s label information regarding the cardiovascular risks associated with Xeljanz, including heart attack and stroke. However, it required company officials to conduct a post-approval study to determine the risk factors associated with cardiovascular events (CVE) and death due to heart failure with Xeljanz.
FDA has now required Pfizer, the drug manufacturer, to conduct a post-approval study evaluating whether there is an increased risk of heart failure and CVEs among rheumatoid arthritis patients taking the dangerous drug.
The study will be known as the Xeljanz Cardiovascular Outcomes Study (XVOS). It is designed to determine whether there is an increased risk of heart failure and cardiovascular death among RA patients taking Xeljanz, compared with other rheumatoid arthritis treatments.
Xeljanz to Treat Rheumatoid Arthritis Research Study
The study will be a large, worldwide, observational registry in patients with RA that have received treatment with Xeljanz to determine if they have an increased rate of heart failure or CVEs compared to rheumatoid arthritis people not treated with Xeljanz. Researchers hope to enroll nearly 40,000 patients with RA that have received at least one prescription for Xeljanz.
The primary objective of XVOS is to determine whether treatment with Xeljanz, as compared to any other DMARDs (disease-modifying antirheumatic drugs) or other treatments for RA, is associated with an increased risk of CVEs.
The Possible Side Effects of Tofacitinib Citrate (Generic Xeljanz)
A side effect is any response that is not desired and occurs with a frequency greater than one percent. Common side effects of tofacitinib citrate can include:
- Musculoskeletal pain
- Abdominal pain
- Fluid retention
- Increased heart rate
- Serious heart-related events
- Increased cardiovascular risk factor
- Major adverse cardiovascular event
- Mouth sores
- Serious infections
- Invasive fungal infections
- Compromised immune system
- Non-melanoma skin cancers
- Elevated cholesterol levels
- Abnormal liver function
- Major adverse cardiovascular events
- Risk of blood clots and death
Because of the serious risks associated with tofacitinib citrate, you should ask your healthcare professionals whether the benefits outweigh the risks before taking this medication.
Xeljanz Lawsuits and the Risk for Blood Clot Risks
Injured patients have filed Xeljanz lawsuits claiming that the prescription drug caused them to develop serious blood clots leading to life-threatening complications.
These plaintiffs seek compensation for the medical treatments, physical pain and suffering, mental anguish, loss of wages and earning capacity, and other damages resulting from their Xeljanz injuries.
Xelijanz Lawsuit FAQs
Our personal injury law firm knows families need answers when injured by dangerous drugs to hold pharmaceutical companies and healthcare professionals accountable when harmed. An attorney specializing in Xeljanz lawsuits has answered some common questions below.
Are Heart Attacks and Strokes Associated with Xeljanz?
Other deadly conditions with severe symptoms associated with taking dangerous medication include heart attacks, strokes, and other cardiovascular problems.
Patients who took this medication were primarily at risk for small vessel ischemic disease (SVID), which occurs when plaque is deposited in the blood vessels, clogging them and preventing sufficient oxygenated blood from reaching the heart.
What Can Patients Do to File a Xeljanz Lawsuit Against the Manufacturer?
Did you take 10mg of Xeljanz twice daily for RA with another medication that decreases blood clotting? Did you suffer from a blood clot, heart attack, stroke, deep vein thrombosis (DVT), pulmonary embolism (PE), major adverse cardiovascular events, or heart-related severe problems caused by a blood clot? You may have a Xeljanz lawsuit against the manufacturer.
Blood clots can occur in any large or medium-sized artery in the body and can be life-threatening. However, the risk of developing a blood clot increases when taking medications known to increase this risk. These medications are referred to as “anticoagulants.”
Blood thinners reduce the risk of blood clots or make them less likely to cause harm.
Is Xeljanz XR Dangerous Too?
Xeljanz XR is a long-acting version of Xeljanz that the FDA has approved. It contains a higher dosage of the active ingredient, tofacitinib, and is given a single dose once a week.
People with rheumatoid arthritis may benefit from taking fewer doses each week, so Xeljanz XR was developed to improve convenience and efficacy.
First, however, the FDA requested a post-marketing safety study on Xeljanz XR be conducted.
According to Xeljanz lawsuit cases filed against Pfizer, two individuals who took Xeljanz for RA suffered from cardiac arrest and died after switching to Xeljanz XR.
The Xeljanz XR lawsuits are pending litigation.
How Does Liability Law Apply to Xeljanz Cases?
Xeljanz patients who took the medication to treat rheumatoid arthritis (RA) or ulcerative colitis have filed lawsuits against the manufacturer, claiming that the drug’s side effects injured them.
Among other allegations, these patients claim that:
- The pharmaceutical company knew of Xeljanz’s risks but failed to warn their consumers properly
- The drugmaker breached its duty to provide safe medication
- The pharmaceutical company acted negligently in conducting formal clinical studies and testing before releasing the prescription drug to the public
Are Patients Taking Medications other than Xeljanz at Increased Risk of Blood Clots?
Patients who take other medications to decrease blood clotting may be at risk of blood clots when taking the medication.
Based on clinical trials and FDA approval, some Xeljanz patients who have taken 10 mg doses twice a day to treat RA with other medications that decrease blood clotting may be at increased risks of developing serious heart-related events, including heart attack, pulmonary embolism, blood clots, or stroke.
