Tacrolimus weakens your body's immune system, to help keep it from "rejecting" a transplanted organ such as a kidney. Organ rejection happens when the immune system treats the new organ as an invader and attacks it.

Tacrolimus is used together with other medicines to prevent your body from rejecting a heart, liver, or kidney transplant.

Tacrolimus may also be used for purposes not listed in this medication guide.
