My seven month old son was prescribed Omnicef for an ear infection four days ago and it was the worst experience we have had yet...worse than colick and worse than reflux. My son who is normally extremely happy and easy going became a monster. He wouldn't eat, wouldn't drink and wouldn't sleep. He would throw a tantrum and swat his bottle out of my hand he wouldn't let me rock him or put him in the bed. He acted like he had gone mad and was very aggressive. It was a horrible experience. I called the doctor back after only one day of being on the medicine and they told me that these weren't side effects of the Omnicef and it was probably just his ears hurting to give it a couple more days. This behavior continued until today when I refused to give him another dose and told the nurse so...she asked if he was on any other cold medicine etc...and he wasn't so they prescribed him augmentin which is what we normally take and have never had a problem. I will never give this medicine to my child again and am not sure I will ever take it myself for sinusitis again either. He also experienced red looking stools but I can't swear that it was bloody but it was definitely a rusty red.
