Omnicef and vitamins

Omnicef did get rid of my son's ear infection, however, he developed Pollakiuria (feeling the urge to urinate constantly throughout the day) which may or may not be related to Omnicef. He did have the clay/reddish stool, but that is a known side effect and is not dangerous. I found out that children should not be given vitamins with iron while on Omnicef - too much iron creates the clay colored stool. I did ask my doctor to report the Pollakiuria as a possible side effect. Drug companies appreciate the information and use it to develop their drugs better. Be sure to report the side effects!

I am a 16 year old girl and I started taking Omnicef 9 days ago, for a soar throat due to the flu. After 3 days I developed diarrhea, and the stools were softned and red. I called the doctor and was told that if I had been taking vitamins or other medications with iron that it would turn the stools red. I was taking vitamins that contained it, so I stopped. Although my stools are no long red, I still have diarrhea. I also experienced severe lower back pains while on this. I have talked to my parents and we decided it was best for me to stop taking the medication, due to my back. I really hope my side effects get better soon.
