Oral rehydration salts: appropriate for children or not?

April 5, 2026

Quick Answer

Oral rehydration salts are appropriate for children, including infants and toddlers, as a treatment for dehydration caused by diarrhea, vomiting, or excessive sweating.

Importance of Oral Rehydration in Children

Oral rehydration salts (ORS) are a vital component of first aid treatment for dehydration in children. According to the World Health Organization (WHO), ORS is the only effective way to treat dehydration, especially in children under the age of 5. A child who is dehydrated needs to be administered 75-100 mL of ORS per kilogram of body weight per day, divided into small, frequent sips.

Preparing Oral Rehydration Salts

ORS packets are widely available at pharmacies and can be prepared by mixing the contents with 1 liter of clean water. The mixture should be stirred well and allowed to cool before administration. It’s essential to note that ORS is not a substitute for medical care, and children showing severe signs of dehydration, such as sunken eyes, low urine output, or lethargy, should be taken to a medical facility immediately. In the meantime, caregivers should provide small sips of ORS every 5-10 minutes to help replenish lost fluids and electrolytes.

Monitoring Dehydration Treatment in Children

Monitoring the child’s response to ORS treatment is crucial to prevent further complications. Signs of effective treatment include increased urine output, improved skin elasticity, and a more alert demeanor. Caregivers should also monitor the child’s temperature, stool output, and overall behavior to adjust the treatment plan as needed. If the child’s condition worsens or does not improve within the first 4-6 hours of treatment, medical attention should be sought immediately.
