Version January 2024
Patients treated with tofacitinib are at increased risk of developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants, such as methotrexate or corticosteroids.
If a serious infection develops, interrupt tofacitinib until the infection is controlled.
Reported infections include:
• Active tuberculosis (TB), which may present with pulmonary or extrapulmonary disease. Patients should be tested for latent TB before tofacitinib use and during therapy. Treatment for latent infection should be initiated prior to tofacitinib use.
• Invasive fungal infections, including cryptococcosis and pneumocystosis. Patients with invasive fungal infections may present with disseminated rather than localized disease.
• Bacterial, viral (including herpes zoster), and other infections due to opportunistic pathogens.
The risks and benefits of treatment with tofacitinib should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection.
Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with tofacitinib, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy.
In a large, randomized, postmarketing safety study in rheumatoid arthritis (RA) patients ≥50 years of age with ≥1 cardiovascular risk factor comparing tofacitinib 5 mg twice a day or tofacitinib 10 mg twice a day to tumor necrosis factor (TNF) blockers, a higher rate of all-cause mortality, including sudden cardiovascular death, was observed with tofacitinib 5 mg twice a day or tofacitinib 10 mg twice a day. Tofacitinib 10 mg twice daily (or tofacitinib XR 22 mg once daily) dosage is not recommended for the treatment of RA or psoriatic arthritis (PsA).
Malignancies, including lymphomas and solid tumors, have occurred in patients treated with tofacitinib and other Janus kinase inhibitors used to treat inflammatory conditions. In RA patients, a higher rate of malignancies (excluding non-melanoma skin cancer [NMSC]) was observed in patients treated with tofacitinib 5 mg twice a day or tofacitinib 10 mg twice a day compared TNF blockers.
Lymphomas and lung cancers were observed at a higher rate in patients treated with tofacitinib 5 mg twice a day or tofacitinib 10 mg twice a day in RA patients compared to those treated with TNF blockers. Patients who are current or past smokers are at additional increased risk.
Epstein-Barr virus-associated posttransplant lymphoproliferative disorder has been observed at an increased rate in renal transplant patients treated with tofacitinib and concomitant immunosuppressive medications.
RA patients ≥50 years of age with ≥1 cardiovascular risk factor, treated with tofacitinib 5 mg twice daily or tofacitinib 10 mg twice daily, had a higher rate of major adverse cardiovascular events (defined as cardiovascular death, myocardial infarction, and stroke), compared to those treated with TNF blockers. Patients who are current or past smokers are at additional increased risk. Discontinue tofacitinib in patients that have experienced a myocardial infarction or stroke.
Thrombosis, including pulmonary embolism, deep venous thrombosis, and arterial thrombosis, have occurred in patients treated with tofacitinib and other Janus kinase inhibitors used to treat inflammatory conditions. Many of these events were serious and some resulted in death. RA patients ≥50 years of age with ≥1 cardiovascular risk factor treated with tofacitinib 5 mg twice daily or tofacitinib 10 mg twice daily compared to TNF blockers had an observed increase in incidence of these events. Avoid tofacitinib in patients at risk. Discontinue tofacitinib and promptly evaluate patients with symptoms of thrombosis.
Note: ER tablets and oral solution are not interchangeable or substitutable. When transitioning from IR tablet to ER tablet, begin ER tablet the day following the last dose of IR tablet. Do not initiate therapy in patients with an absolute lymphocyte count <500 cells/mm3, ANC <1,000 cells/mm3, or hemoglobin <9 g/dL.

Lymphocytopenia (after an initial lymphocytosis), neutropenia, and anemia have been observed with tofacitinib therapy. Thrombocytopenia has also been reported (Ref). In an open-label long-term extension study over 9.5 years, potentially life-threatening lymphocytopenia (<500 cells/mm3) occurred in ~1% of patients; <1% of these patients developed serious infections. Moderate to severe neutropenia occurred in ~1% and <1% of patients, respectively; no patients developed serious infections (Ref). In another study, <1% of patients experienced a clinically significant decrease in hemoglobin (defined as a ≥3 g/dL decrease from baseline or hemoglobin ≤7 g/dL) (Ref). Cell counts typically stabilize with continued treatment; for cases requiring discontinuation, partial or complete resolution usually occurred (Ref).
Mechanism: Dose-related; may impair pro-growth signaling in bone marrow stem cells (Ref).
Onset: Delayed. Lymphocytopenia: Increases in lymphocyte counts in the first 3 months, followed by decreases for up to 48 months. Neutropenia: Decreases in the first 24 months (Ref).
Risk factors:
• Higher doses (Ref)
Data regarding risk of major cardiovascular events (MACE) with tofacitinib are unclear. In a long-term open-label extension study over 9.5 years, the rate of cardiovascular events was low (Ref). Another study over a median follow-up of 4 years found an increased risk of MACE (including acute myocardial infarction and cerebrovascular accident) in patients ≥50 years of age with rheumatoid arthritis (RA) receiving tofacitinib compared to patients receiving tumor necrosis factor inhibitors (Ref). Furthermore, a study using a simulated clinical trial cohort with real world data found a small but statistically insignificant increase in cardiovascular outcomes (Ref). However, in a large registry of patients with RA, the rate of MACE was similar to patients receiving biological disease-modifying drugs (Ref), and a World Health Organization database also failed to find an association (Ref).
Mechanism: Unknown; although, tofacitinib increases lipid levels by reducing cholesterol ester metabolism (Ref).
Risk factors:
• Age ≥65 years (Ref)
• Cardiovascular risk factors (eg, current or former smokers)
Gastrointestinal (GI) perforation has been reported, typically secondary to diverticulitis, and may be life-threatening. Most perforations have occurred in the lower GI tract (Ref). Incidence was rare in patients with rheumatoid arthritis in long-term studies; lower incidence than tocilizumab but higher incidence than tumor necrosis factor inhibitors (Ref).
Onset: Varied; may occur weeks to years after initiation (Ref).
Risk factors:
• Older age (Ref)
• Concurrent glucocorticoids (ie, prednisone ≥7.5 mg/day) or nonsteroidal anti-inflammatory drugs (Ref)
• History of diverticulitis/other GI conditions (Ref)
Increased liver enzymes may occur, which are usually mild and transient and rarely result in dose adjustment or discontinuation (Ref). Hepatotoxicity is rare (Ref).
Mechanism: Unknown, dose-related; metabolized in the liver through the CYP 3A4 pathway. Hepatotoxicity may be related to the production of a toxic or immunogenic intermediate (Ref).
Risk factors:
• Higher doses (Ref)
• Concurrent use of conventional synthetic disease modifying antirheumatic drugs (Ref)
Patients receiving tofacitinib are at increased risk for infection (including serious infection), which may result in hospitalization and/or fatality. Infections may present as disseminated (rather than local) disease. Active tuberculosis (including disseminated), invasive fungal infection (including cryptococcosis and pneumocystosis), bacterial infection, viral infection, or other opportunistic infection have been reported. Nasopharyngitis, upper respiratory tract infections, and urinary tract infections are the most common infections (Ref). Other infections, including appendicitis, cellulitis, diverticulitis of the gastrointestinal tract, herpes zoster infections (including disseminated cutaneous, meningoencephalitis, ophthalmologic) and reactivation of hepatitis B virus have also been reported. One study over a median follow-up of 4 years found an increased risk of infections in patients ≥50 years of age with rheumatoid arthritis (RA) receiving tofacitinib compared to patients receiving tumor necrosis factor inhibitors (Ref). In additional studies in patients with RA, the incidence of herpes zoster in patients receiving tofacitinib was more than twice that in patients receiving biological disease modifying drugs (DMARDs) (Ref).
Mechanism: Dose-related; may impair lymphocyte function, leading to suppression of immune response and increased risk of infection (Ref).
Onset: Delayed; median exposure prior to diagnosis of an opportunistic infection was 8 months (range: ~40 days to ~2 years).
Risk factors:
• Higher doses (Ref)
• Older age (Ref)
• Concurrent immunosuppressants (eg, corticosteroids, conventional synthetic DMARDS (Ref)
• Asian ethnicity (for herpes zoster) (Ref)
• Females (Ref)
• Lymphocytopenia (<500 cells/mm3) (Ref)
• History of an opportunistic infection
• Chronic or recurrent infection
• Conditions that predispose to infections (eg, advanced or poorly controlled diabetes)
• Residence/travel in areas of endemic tuberculosis or mycoses (blastomycosis, coccidioidomycosis, histoplasmosis)
Malignant neoplasm, including malignant lymphoma and malignant solid tumor, have occurred in patients treated with tofacitinib and other Janus kinase inhibitors for the treatment of inflammatory conditions. The most common types of malignancy observed were lung carcinoma, malignant neoplasm of the breast, gastric carcinoma, malignant neoplasm of colon or rectum, renal cell carcinoma, prostate carcinoma, malignant lymphoma, pancreatic adenocarcinoma, and malignant melanoma. One study over a median follow-up of 4 years found an increased risk of malignancies in patients ≥50 years of age with rheumatoid arthritis (RA) receiving tofacitinib compared to patients receiving tumor necrosis factor inhibitors (TNFi) (Ref). In contrast, no increase in risk of malignancies in general or of any specific type was detected compared to patients with RA receiving conventional synthetic disease modifying drugs (DMARDs) or with TNFi in earlier meta-analyses of randomized clinical trials (Ref). In two large registries of patients with RA, the rate of malignancy in patients receiving tofacitinib was similar to patients receiving biological DMARDs or with TNFi (Ref).
Mechanism: Not clearly established; may inhibit immunosurveillance to malignancy (Ref).
Risk factors:
• Age ≥65 years (Ref)
• Current or former smoker
Thrombosis, including arterial thrombosis, deep vein thrombosis, and pulmonary embolism, have occurred in patients treated with tofacitinib and other Janus kinase (JAK) inhibitors used to treat inflammatory conditions. One study over a median follow-up of 4 years found an increased risk of venous thrombosis and pulmonary embolism in patients ≥50 years of age with rheumatoid arthritis (RA) receiving tofacitinib compared to patients receiving tumor necrosis factor inhibitors (TNFi) (Ref). However, in multiple large registries of patients with RA and other patients, the rate of thrombotic events with tofacitinib was low and similar to patients who used biological disease modifying drugs or TNFi (Ref).
Mechanism: Dose-related; JAK inhibition may affect a variety of pathways affecting endothelial activation and platelet aggregation (Kotyla 2021). Tofacitinib may also have off-target effects not related to JAK inhibition (Ref).
Risk factors:
• Higher doses (Ref)
• Cardiovascular or venous thromboembolic risk factors (Ref)
Active tuberculosis (TB), which may present with pulmonary or extrapulmonary disease, has been reported. One study over a median follow-up of 4 years found an increased risk of TB in patients ≥50 years of age with rheumatoid arthritis (RA) receiving tofacitinib compared to patients receiving tumor necrosis factor inhibitors (Ref). In a meta-analysis of randomized clinical trials, the risk of TB in patients receiving tofacitinib at any dose was higher versus placebo but not statistically significant (Ref).
Mechanism: Dose-related; may impair lymphocyte function, leading to suppression of immune response and increased risk of infection (Ref).
Risk factors:
• Higher dose (Ref)
• Residence in an area with high TB prevalence
• Known TB exposure or ongoing risk factors for TB exposure (eg, travel to areas with high TB prevalence)

There are no contraindications listed in the manufacturer's US labeling.
Canadian labeling: Hypersensitivity to tofacitinib or any component of the formulation; severe hepatic impairment; pregnancy; breastfeeding.
Concerns related to adverse effects:
• Hypersensitivity: Hypersensitivity reactions, including angioedema and urticaria, have occurred; discontinue therapy and evaluate cause for serious reactions.
• Interstitial lung disease: Interstitial lung disease (ILD) has been reported; patients developing ILD were receiving concomitant therapy associated with ILD (eg, methotrexate). Use with caution in patients with risk/history of ILD (Xeljanz Canadian product monograph).
Disease-related concerns:
• Active infections: Do not initiate tofacitinib in patients with active infections, including localized infections.
• Hepatic impairment: Use with caution in patients with hepatic impairment; see "Dosing: Hepatic Impairment" for additional information.
• Lung disease: Patients with a history of chronic lung disease or those who develop interstitial lung disease may be more prone to infections; use with caution.
• Renal impairment: Use with caution in patients with renal impairment; see "Dosing: Altered Kidney Function" for additional information.
Concurrent drug therapy issues:
• Immunosuppressant medications: Tofacitinib should not be administered in combination with strong immunosuppressive medications (eg, azathioprine, tacrolimus, cyclosporine) due to the risk of additive immunosuppression; such combinations have not been studied in RA.
• Biologic disease-modifying antirheumatic drugs: Tofacitinib should not be administered in combination with biologic disease-modifying antirheumatic drugs.
Special populations:
• Asian patients: Use with caution in Asian patients; an increased incidence of adverse reactions (eg, herpes zoster, opportunistic infections, decreased WBC, interstitial lung disease, increased transaminases) has been observed (Wollenhaupt 2014; Xeljanz Canadian product monograph).
• Patients with rheumatic musculoskeletal disease undergoing hip or knee replacement surgery: Hold tofacitinib for at least 3 days prior to surgery to reduce infection risk; therapy can be restarted once surgical wound shows evidence of healing (eg, no swelling, erythema, or drainage), sutures/staples are removed, and no ongoing nonsurgical site infections (typically ~14 days to reduce infection risk) (ACR/AAHKS [Goodman 2022]).
Dosage form specific issues:
• Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol and/or sodium benzoate/benzoic acid; benzoic acid (benzoate) is a metabolite of benzyl alcohol. Large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity ("gasping syndrome") in neonates. The "gasping syndrome" consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982). Some data suggest that benzoate displaces bilirubin from protein-binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol and/or benzyl alcohol derivative with caution in neonates. See manufacturer's labeling.
• Extended release: Use caution when administering the ER formulation to patients with preexisting severe GI narrowing (pathologic or iatrogenic). There have been rare reports of obstructive symptoms in patients with known strictures following ingestion of other medications that also utilize a nondeformable ER formulation. The inert tablet shell of the ER tablet may be noticeable in the stool (or colostomy); the active medication will have been already absorbed.
• Non-interchangeability of dosage forms: ER tablets are not interchangeable or substitutable with the oral solution.
Other warnings/precautions:
• Immunizations: Immunization status should be current before initiating therapy. Live vaccines should not be given concomitantly with tofacitinib; recommended interval between receipt of live vaccines and initiation of immunosuppressive agents, such as tofacitinib, should follow current vaccination clinical guidelines. Dissemination of the vaccine strain of varicella zoster virus has been reported in a varicella virus-naive patient 16 days following vaccination with Zostavax (live attenuated zoster) and 2 days after the initiation of tofacitinib.

Recommendations for use of tofacitinib to treat rheumatic and musculoskeletal diseases in patients planning to become pregnant or who are planning to father a child are not available due to lack of data (ACR [Sammaritano 2020]).
Agents other than tofacitinib are preferred to treat inflammatory bowel disease in patients planning to become pregnant. Disease management should be optimized prior to pregnancy. Tofacitinib should be avoided or used with caution prior to a planned pregnancy; discontinue 1 week prior to conception to limit first trimester fetal exposure (Mahadevan 2019).
Outcome data following tofacitinib exposure during pregnancy are limited (Clowse 2016; Fernández-Sánchez 2021; Mahadevan 2018).
Recommendations for use of tofacitinib in pregnant patients with rheumatic and musculoskeletal diseases are not available due to lack of data. Placental transfer may be expected based on molecular weight (ACR [Sammaritano 2020]).
Inflammatory bowel disease is associated with adverse pregnancy outcomes, including an increased risk of miscarriage, premature delivery, delivery of a low-birth-weight infant, and poor maternal weight gain. Management of maternal disease should be optimized prior to pregnancy. Treatment decreases disease flares, disease activity, and the incidence of adverse pregnancy outcomes. When treatment for inflammatory bowel disease is needed in pregnant patients, use of tofacitinib should be avoided at least during the first trimester (Mahadevan 2019).
Tofacitinib is under study for the treatment of COVID-19 (NIH 2023). The risk of severe illness from COVID-19 infection is increased in pregnant patients compared to nonpregnant patients. Pregnant and recently pregnant patients with moderate or severe infection are at increased risk of complications such as hypertensive disorders of pregnancy, postpartum hemorrhage, or other infections compared to pregnant patients without COVID-19. Pregnant patients with symptoms may require ICU admission, mechanical ventilation, or ventilatory support (extracorporeal membrane oxygenation) compared to symptomatic nonpregnant patients. Other adverse pregnancy outcomes include preterm birth and stillbirth. The risk of coagulopathy, cesarean delivery, and maternal death may be increased; neonates have an increased risk for NICU admission. Maternal age and comorbidities such as diabetes, hypertension, lung disease, and obesity may also increase the risk of severe illness in pregnant and recently pregnant patients (ACOG 2023; NIH 2023).
In general, the treatment of COVID-19 infection during pregnancy is the same as in nonpregnant patients. However, because data for most therapeutic agents in pregnant patients are limited, treatment options should be evaluated as part of a shared decision-making process. Use of an agent other than tofacitinib may be preferred (NIH 2023). Information related to the treatment of COVID-19 during pregnancy continues to emerge; refer to current guidelines for the treatment of pregnant patients.
It is not known if tofacitinib is present in breast milk.
Recommendations for use of tofacitinib in breastfeeding patients with rheumatic and musculoskeletal diseases are not available due to lack of data. Transfer into breast milk may be expected based on molecular weight (ACR [Sammaritano 2020]). Tofacitinib is not recommended to treat inflammatory bowel disease in patients who are breastfeeding (Mahadevan 2019). Due to the potential for serious adverse reactions in the breastfed infant, the manufacturer does not recommend breastfeeding during treatment and for at least 18 hours after the last dose of immediate release tofacitinib or 36 hours (~6 half-lives) after the last dose of tofacitinib extended-release.
Lymphocyte count (baseline and every 3 months thereafter); neutrophil/platelet counts (baseline, after 4 to 8 weeks, and every 3 months thereafter); hemoglobin (baseline, after 4 to 8 weeks, and every 3 months thereafter); lipids (4 to 8 weeks after therapy initiation and periodically); LFTs; viral hepatitis (prior to initiating therapy in accordance with clinical guidelines); signs/symptoms of infections (including tuberculosis) during and after therapy; abdominal symptoms; skin examinations (periodically, in patients at increased risk for skin cancer); heart rate and blood pressure at baseline and periodically thereafter.
Tofacitinib inhibits Janus kinase (JAK) enzymes, which are intracellular enzymes involved in stimulating hematopoiesis and immune cell function through a signaling pathway. In response to extracellular cytokine or growth factor signaling, JAKs activate signal transducers and activators of transcription (STATs), which regulate gene expression and intracellular activity. Inhibition of JAKs prevents cytokine- or growth factor-mediated gene expression and intracellular activity of immune cells, reduces circulating CD16/56+ natural killer cells, serum IgG, IgM, IgA, and C-reactive protein, and increases B cells.
