My daughter was prescribed Omnicef for an ear infection. Almost a week into the dosing she developed a severe rash all over her body. She also was very "sensitive" while on the meds, which it's hard to tell if it was the meds or just not feeling well. But my son has been on this med before and had the orange/red stools. After reading all of these posts I will never allow him to take this medication again. I'm just keeping my fingers crossed that we have seen the worst of her rash and she can start to get on the road to recovery.
