My 13 month old son has been taking Omnicef for 6 days now in 2 2.5 mL doses per day. He has been very whiney and clingy to me and has had the worst diarhea I have ever seen. He has also been running a fever every day upwards of 103. I just changed 4 diapers in less than an hour. I refuse to give him any more of this medication. He does not seem well at all. I'm at a loss. Amoxiclin didn't clear up his ear infection and the doctor gave him this. I will call tomorrow and ask what to do.
