Omnicef and couple of days

My 1 year old was prescribed Omnicef for a possible sinus infection. Before she started taking this med she had a little cough and a runny nose, not that bad at all. The doctor thought she should go on this for 14 days to help. She has been on the med for 4 days, and her symptoms have gotten worse. She is coughing all the time, she is having massive maroon colored runny stools, and she has a horrible diaper rash. She has started to get a welt on her thigh, and rash around her cheeks and chin. I am currently waiting for the doctor to call us back regarding the problems she is having. I am so glad I found this website, and know that I am not being paranoid. My daughter is the most even keeled baby you will ever meet, but the last couple of days she has been crying all the time as if she is in pain. I have stopped the medication and will never allow her to take this medicine again!!!!

My five year old was in the hospital for 4 days for a sinus infection and they put her on Omnicef. My daughter is a very cheerful little girl and these last couple of days she has been everything but cheerful. Its as she has turned into a demon over night. She has been having the worst mood swings. She has been screaming, yelling back, and kicking her legs and just being really mean. I remember the nurse advising me the possibility of a change in mood swings but I never imagined this. Omnicef did it's purpose BUT I hope to never have to use it again. I was not prepared for the mood swings my child acted out. I thought it was just my child until I started reading online and asking around.
