Interactions between your drugs

Major

tofacitinib deuruxolitinib

Applies to: Xeljanz XR (tofacitinib) and deuruxolitinib

GENERALLY AVOID: Coadministration of deuruxolitinib with other Janus Kinase (JAK) inhibitors, biologic immunomodulators, or other potent immunosuppressants (e.g., cyclosporine) may potentiate the risk of infections, major adverse cardiovascular events (MACE), and other malignancies, including lymphomas. Serious and sometimes fatal infections including bacterial, mycobacterial (e.g., tuberculosis), fungal, viral including viral reactivation, and other opportunistic infections have been reported in patients who have received deuruxolitinib. Opportunistic infections include tuberculosis, multidermatomal herpes zoster, oral/esophageal candidiasis, and cryptococcosis. Lymphoma and other malignancies, including non-melanoma skin cancers, have also been observed with the use of deuruxolitinib and other Janus kinase (JAK) inhibitors.

MANAGEMENT: Concomitant use of deuruxolitinib with other Janus kinase (JAK) inhibitors, biologic disease-modifying antirheumatic drugs (DMARDs), or potent immunosuppressants (e.g., azathioprine, cyclosporine) is not recommended. Patients receiving deuruxolitinib 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 patient develops a serious infection, deuruxolitinib therapy should be interrupted until the infection is controlled.

Drug and food/lifestyle interactions

Moderate

tofacitinib food/lifestyle

Applies to: Xeljanz XR (tofacitinib)

MONITOR: Grapefruit juice may increase the plasma concentrations of tofacitinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. The extent and clinical significance are unknown. Moreover, pharmacokinetic alterations associated with interactions involving grapefruit juice are often subject to a high degree of interpatient variability.

MANAGEMENT: Until more information is available, some authorities recommend avoiding consumption of grapefruit juice during tofacitinib therapy (Canada). Patients receiving tofacitinib therapy who ingest grapefruits or grapefruit juice should be monitored for adverse effects and undue fluctuations in plasma drug levels.

Moderate

deuruxolitinib food/lifestyle

Applies to: deuruxolitinib

MONITOR: Smoking during treatment with deuruxolitinib may increase the risk of major adverse cardiovascular events (MACE) and the risk of developing malignancies. In clinical studies of deuruxolitinib, individuals who were current or former smokers had an additional increased risk of overall malignancies. Also, deuruxolitinib may increase patients' risk of MACE, including myocardial infarction, stroke, and cardiovascular death.

MANAGEMENT: Caution is advised if deuruxolitinib is prescribed to current or past smokers. Patients should be informed about the symptoms of serious cardiovascular events and the steps to take if they occur. The manufacturer recommends discontinuing deuruxolitinib in patients that have experienced a myocardial infarction or stroke. Deuruxolitinib may be taken with or without food.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
