Prograf® (
tacrolimus) is an immunosuppressant used to prevent organ rejection in people who have had a heart, liver, or kidney transplant.
Prograf works by suppressing the immune system, making it less active. The body's natural response to a foreign material, such as a newly transplanted organ, is to attack it. Because Prograf makes the immune system less active, it can help prevent transplant rejection from occurring.
