Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration of etrasimod with antineoplastic, immunosuppressive, or other immune-modulating therapies may increase the risk of unintended additive immunosuppressive effects. Etrasimod causes reversible sequestration of lymphocytes in lymphoid tissues. When administered daily for 52 weeks, etrasimod produced a mean reduction in peripheral blood lymphocyte count to 45% of baseline values, which may increase the risk of infections. Life-threatening and rare fatal infections have occurred in association with other sphingosine 1-phosphate (S1P) receptor modulators. Decreased lymphocyte counts persist during chronic daily dosing and generally return to normal within 4 to 5 weeks after stopping the medication.

MANAGEMENT: The safety and efficacy of etrasimod in combination with antineoplastic, immunosuppressive, or immune-modulating agents have not been evaluated. Because its pharmacodynamic effects may persist for up to 5 weeks after treatment discontinuation, concomitant use during and within 5 weeks following the last dose of etrasimod with antineoplastic, immunosuppressive, or immune-modulating agents should generally be avoided. If concomitant use within this period is considered necessary, patients should be monitored for infectious complications during this extended period. When switching from drugs with prolonged immune effects to etrasimod, the half-life and mode of action of these drugs must also be considered to avoid unintended additive immunosuppressive effects.
