Ask your doctor what fluids are best for you or your child. Here are some basic tips: Give an adult plenty of clear fluid, like fruit juices, soda, sports drinks and clear broth. Avoid milk or milk-based products, alcohol, apple juice, and caffeine while you have diarrhea and for 3 to 5 days after you get better. They may make diarrhea worse. Give a child or infant frequent sips of a rehydration solution such as Pedialyte, CeraLyte, or Infalyte. Do not add salt tablets to a baby’s bottle.
