Does anyone know about prednisone side effects? I got a steroid shot for poison ivy and was given a prescription for prednisone. I started the pills on Tuesday and today I have had to go to the bathroom ALOT! It started about 830pm going to the potty but i didnt feel great around 1 this afternoon. Is this a virus or a side effect? Its now 1 am and i am still going only now its all clear and its not a lot but my stomach is still grumbling. HELP! I am not feeling nauseated but I am afraid that might come later. Will it come on so much later after the bathroom visits began?
