Zinc Supplementation for Children with Diarrhea

Recommended Dose and Administration

For a 1-year-old child weighing 10 kg with acute diarrhea, the American Academy of Pediatrics recommends 20 mg of elemental zinc daily for 10-14 days, as this falls within the 6 months to 5 years age range where the higher dose has strong evidence for reducing diarrhea duration by approximately 10-27 hours 1, 2
The World Health Organization recommends zinc supplementation for children with diarrhea, with a dose of 20 mg daily for 10-14 days for children 6 months to 5 years old 1, 2

The Centers for Disease Control and Prevention recommends oral rehydration therapy (ORS) as the cornerstone of diarrhea management, with assessment of dehydration severity and administration of 50-100 mL/kg ORS over 2-4 hours depending on the level of dehydration 3
The American Academy of Pediatrics recommends replacing each watery stool with 10 mL/kg of ORS to prevent dehydration 3

The Centers for Disease Control and Prevention recommends continuing breastfeeding throughout the diarrheal episode, and resuming age-appropriate usual diet immediately after rehydration 3, 4
The American Academy of Pediatrics recommends not restricting diet or prolonging fasting, as this worsens nutritional status 3, 2

The American Academy of Pediatrics recommends never using antimotility drugs (like loperamide) in children under 18 years, as these carry serious risks including respiratory depression 3, 2
The World Health Organization recommends not delaying or substituting zinc for proper rehydration therapy, as zinc supplementation is most beneficial when started within 3 days of diarrhea onset 3

The World Health Organization recommends zinc supplementation for children residing in countries with high zinc deficiency prevalence, as well as children with signs of malnutrition or stunted growth 1, 2

The American Society for Infectious Diseases strongly recommends zinc supplementation for children aged 6 months to 5 years with acute gastroenteritis, residing in countries with high zinc deficiency prevalence or showing signs of malnutrition, at a dose of 20 mg of elemental zinc daily for 10-14 days, with moderate evidence supporting this intervention 5, 6
Zinc reduces the duration of diarrhea by approximately 10 hours in the general population and up to 27 hours in children with signs of malnutrition 5, 6

The Infectious Diseases Society of America prioritizes zinc supplementation in children residing in countries with high zinc deficiency prevalence, children with signs of malnutrition or growth retardation, and children with high gastrointestinal losses 5, 6
For children on parenteral nutrition, the recommended zinc supplementation doses are: 400-500 μg/kg/day for preterm infants, 250 μg/kg/day for term infants (0-3 months), 100 μg/kg/day for infants (3-12 months), and 50 μg/kg/day (maximum 5 mg/day) for children over 12 months 7

The American Academy of Pediatrics recommends routine zinc supplementation for children receiving parenteral nutrition, with specific dosing guidelines based on age and weight 7
