Theoretically, agents that are thought to have immunostimulant properties such as echinacea, vitamin E, cat's claw, and zinc may antagonize the pharmacologic effects of immunosuppressants. However, clinical cases of drug interactions have not been reported.

Drug and food interactions
tofacitinib food
Applies to: 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.
