Hi, I am about to have a CT scan this morning at 8.30 I am currently not allowed to eat anything until then. I know that I am not supposed to take my Metformin (for diabetes); but I forgot to check the prednisone. I take 8 tabs with my breakfast. So do I take 8 tabs at normal time with no food? Or do I wait till about 10 am when I am finished and get some food and take them then?
