“GOLO release Diet Pills?”

I am a kidney transplant patient and I have recently started taking GOLO Release to help curb hunger and help in some weight loss. I take Cylosporine as well as other meds for cardiac A Fib, and BP meds. Is it ok to be taking GOLO? The ingredients looked ok, but I want to be sure it is ok to take it. My doc has not responded to my inquiries.
