ruxolitinib tofacitinib

Applies to: ruxolitinib and tofacitinib

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration of tofacitinib with other immunosuppressive agents may potentiate the risk of infections as well as lymphoma and other malignancies. Serious and sometimes fatal infections due to bacterial, mycobacterial, invasive fungal, viral, or other opportunistic pathogens have been reported in patients receiving tofacitinib, most of whom were taking concomitant immunosuppressants such as methotrexate or corticosteroids. Lymphoma and other malignancies, including melanoma and non-melanoma skin cancers, have also been observed with tofacitinib use. Epstein Barr virus-associated posttransplant lymphoproliferative disorder has been observed at an increased rate in renal transplant patients treated with tofacitinib and concomitant immunosuppressive agents (basiliximab, high-dose corticosteroids, and mycophenolic acid) relative to cyclosporine plus the same induction regimen (2.3% vs. 0%).

MANAGEMENT: Tofacitinib should not be used in combination with other Janus kinase inhibitors, biologic disease-modifying antirheumatic drugs (DMARDs), or potent immunosuppressants (e.g., azathioprine, cyclosporine). Patients receiving tofacitinib should be closely monitored for the development of signs and symptoms of infection during and after treatment, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. If a serious infection, an opportunistic infection, or sepsis develops, tofacitinib should be interrupted until the infection is controlled.

Drug and food interactions


ruxolitinib food

Applies to: ruxolitinib

Do not consume grapefruit or grapefruit juice during treatment with ruxolitinib unless directed otherwise by your doctor. Grapefruit juice can increase the blood levels of ruxolitinib. This may increase the risk of side effects that affect your bone marrow function, resulting in low numbers of different types of blood cells. You may be more likely to develop anemia, bleeding problems, or infections. Contact your doctor if you experience potential signs and symptoms of these conditions such as paleness, fatigue, dizziness, fainting, unusual bleeding or bruising, fever, chills, sore throat, body aches, or other flu-like symptoms. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
