hey my friend!!!
hmmm...I"ve not heard of it...but this is what I got from the internet.
Prograf® (tacrolimus) is indicated for the prophylaxis of organ rejection in patients receiving allogeneic liver, kidney, or heart transplants.
The principal adverse reactions of Prograf are tremor, headache, diarrhea, hypertension, nausea, and abnormal renal function. These occur with oral and IV administration of Prograf and may respond to a reduction in dosing. Diarrhea was sometimes associated with other gastrointestinal complaints such as nausea and vomiting. (diarrhea? hmmm...like you need that?)
sorry, I don't have much info, and you probably already know all this info...but if you need more info, call the doc that prescribed it for you..they are supposed to provide all that info for you when you're prescribed.
