my 9 month old was put on this medication for an ear infection last week. 24 hours after taking the first does she began throwing up and continued for 3 days doing that. I finally stopped giving it to her once I figured it was the medication causing her to throw up and called her doctor and have asked for something different. She is obviously allergic to it. She also had bad diarrhea and became dehydrated almost to the point that I was about to take her to the ER. I don't like this drug at all!
