Suggest Treatment For Diarrhea And Dizziness Caused Due To Stomach Bug

My daughter had the stomach bug yesterday. It started at 6 pm and puking and diahrea. Now today she slept all day. And has a fever now and is dizzy. She has had a little bit of kix and I would say about 12 oz. of water. Should I take her to the hospital or could I give her some medicine?
