Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration of topical tacrolimus with other immunosuppressive agents may potentiate the immunosuppressive effects of topical tacrolimus. However, data concerning its safety and efficacy in combination with immunosuppressants are not available. According to the prescribing information, rare cases of skin malignancy and lymphoma have been reported in patients who have received treatment with topical calcineurin inhibitors, including topical tacrolimus. On the other hand, systemic exposure from topical tacrolimus is reported to be less than 1 ng/mL. In addition, the lowest tacrolimus blood concentration from topical application at which systemic effects can be observed is unknown.

MANAGEMENT: According to the manufacturer, use of topical tacrolimus in immunocompromised patients is not recommended. Therefore, until further information is available, it may be advisable to avoid its concomitant use with other immunosuppressants. Screening for the development of malignancy during and after treatment may also be considered.
