Tacrolimus can lower the blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. To be sure your blood cells do not get too low, your blood will need to be tested on a regular basis. Your kidney or liver function may also need to be tested. Do not miss any scheduled appointments.
Some people receiving tacrolimus after a kidney transplant have developed diabetes, most often in people who are Hispanic or African-American. Talk with your doctor about your individual risk of diabetes.
What is tacrolimus?
Tacrolimus lowers your body's immune system. The immune system helps your body fight infections. The immune system can also fight or "reject" a transplanted organ such as a liver or kidney. This is because the immune system treats the new organ as an invader.
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 other purposes not listed in this medication guide.
