I was prescribed Omnicef for my bad sinus infection. On the 3rd day I stopped this medication due to terrible black diarrhea. It continued for 4 days, though by the 4th day it was better. Due to the constant diarrhea, I had a slight problem with hemorroids, which is now gone. The thing is I haven't been feeling like myself since taking this medication. I felt a little paranoid and anxiety that I had to call my doctor and inform her that I stopped this medication. I'll be seeing her tomorrow.
