My 12 month old granddaughter was given Ominicef for an ear infection. For two nights in a row she would wake up in the middle of the night crying, and unable to go back to sleep. Her playful attitude change to crankiness. She threw her toys, had crying fits and developed a diaper rash. A couple of days later I noticed blotches on her face which cleared up when the Omnicef was stopped. The Omnicef did not clear her ear infection. A week after taking the Ominicef she began wheezing and had difficult breathing. She was diagnosed with asthma, which I am now wondering could possibly have been brought on by the Omnicef?
