Baby has diarrhea

Madeline

My 1yr old threw up Tuesday night and then Wednesday morning he started getting diarrhea. It's so bad that each time it's a blow out. I've given him pedialyte and bland foods, but nothing is working. His pediatrician is gone for the weekend and the whole pediatric office is closed until Monday. What should I do? Should I take him to the hospital if it continues this weekend? What medicine can I give him?
