I was prescsribed Omnicef for sinusitis. On Day#2 I began having diarrhea. Thought I'd stick with the regimen, but on Day #5 stopped taking it as having severe diarrhea everytime I went to the bathroom. It is almost a week now since I started taking it and my bowels are not back to normal yet. Have call in to doctor's office for seomthing to relieve the diarrhea as Immodium does not work (pharmacy insert with medicine said as much--OTC remedies will not help--and it's true!) I am 50 years old, in good health otherwise, but this med knocked me for a loop! Will NEVER take it again. PS Did not help the sinusitis, either.
