Our one and a half year old son was put on this drug for ear infection and within one day it was like Dr. Jeckyl and Mr. Hyde. He had constant diarrhea, stomach cramping, waking up in the middle of the night screaming. But most disturbing was the behavior changes of just screaming and yelling all the time and the agressive behavior, even toward himself(biting his hand). It was like someone took our soft spoken, easy going happy son away from us. He is still having stomach problems and waking up at night. His eating has slowed way down. I will never give this drug to him again.
