Can you take percocet and Prednisone together?

I would say not too not every one will b the same. But i was on predisone. For the 2nd time and was on the 2nd day off and was taking ibp 800 mg 3 every 4 hrs. And it caused me to lose my memory, and flip out bad . And really massed me up. Told my doc after that i was taking the ibp 800mg . Instead, of the valium cause i was taking two many a day for me i felt. So i took ibp instead for a break. And he told me that predisone, and ibp was dangerous together. So did the pharmacists. I would b careful.
