Cefdinir
"My 11 yr old daughter had a sinus infection and was prescribed 300mg 2 times a day. Within an hr of the first dose she became VERY ill. Turned Pamela white and eyes dialled as if she were going to pass out. I called the dr immediately and they said the effects would pass. We discontinued immediately and was prescribed a different antibiotic and she was fine. This drug is horrible and can't believe it's still being used."
