Artificial flavor. Quickly replaces fluid and electrolytes lost during diarrhea and vomiting to help prevent dehydration when mixed with water. No 1 pediatrician recommended brand. Dehydration can make your sick child feel even worse. Use Pedialyte rather than juices, soda, sports drinks or water, at the first sign of diarrhea and vomiting to help replace lost fluid and electrolytes. Pedialyte is scientifically designed to help replace electrolytes, like sodium, lost during diarrhea more effectively than common beverages (leading sports drinks, soda, 100% apple juice, water).
