Oral Rehydration Solutions for Children

Topic Overview

When a child has diarrhea or is vomiting, it is important to prevent dehydration. Oral rehydration solutions (ORSs), such as Pedialyte, are used to prevent or correct dehydration in young children. ORSs contain the right mix of salt, sugar, potassium, and other minerals to help replace lost fluids.

In the first 4 to 6 hours after diarrhea or vomiting has started, give your child the following amount of ORS.

If your baby is less than 2 months old, talk to the doctor about your baby's symptoms before starting ORS fluids.

Allow your child to drink as much fluid as he or she wants. Small amounts at frequent intervals are usually better tolerated. Replace any additional fluid lost through diarrhea or vomiting.

Watch for signs of dehydration. If your child develops signs of dehydration, increase the amount of fluid you are giving.
