Pedialyte Dosage for a 10-Month-Old Infant

For a 10-month-old infant, Pedialyte should be administered at 60-120 mL for each diarrheal stool or vomiting episode, up to a maximum of 500 mL per day. 1

Dosage Guidelines Based on Dehydration Status

For Prevention/Maintenance of Hydration

  • For infants weighing less than 10 kg (typical for a 10-month-old), provide 60-120 mL of Pedialyte for each diarrheal stool or vomiting episode 1
  • Continue replacement as long as diarrhea or vomiting persists 1
  • Maximum daily intake should not exceed approximately 500 mL per day 1

For Mild to Moderate Dehydration

  • For mild dehydration (3-5% fluid deficit): administer 50 mL/kg of Pedialyte over 2-4 hours 2, 3
  • For moderate dehydration (6-9% fluid deficit): administer 100 mL/kg of Pedialyte over 2-4 hours 2, 3
  • After rehydration is complete, switch to the maintenance dosing described above 1

Administration Tips

  • Start with small volumes (e.g., one teaspoon) using a teaspoon, syringe, or medicine dropper if the infant is vomiting 3
  • Gradually increase the amount as tolerated 3
  • Offer Pedialyte at room temperature 1
  • Continue breastfeeding throughout the diarrheal episode if applicable 2, 4
  • Resume age-appropriate formula and foods during or immediately after rehydration 2, 4

Monitoring Response

  • Reassess hydration status after 2-4 hours of rehydration 2, 3
  • Monitor for signs of improvement or deterioration in hydration status 4
  • Watch for clinical signs including skin turgor, mucous membrane moisture, and mental status 3

Important Considerations

  • Pedialyte (45 mEq/L sodium) is primarily intended for maintenance of hydration and prevention of dehydration 1
  • While solutions with higher sodium concentrations (75-90 mEq/L) are preferable for rehydration, Pedialyte can be used when the alternative is physiologically inappropriate liquids or IV fluids 1
  • Pedialyte has been shown to be effective for rehydration of infants with mild to moderate dehydration 5
  • Caretakers have reported high satisfaction with oral rehydration solutions including Pedialyte 6

When to Seek Medical Attention

  • If signs of severe dehydration develop (lethargy, decreased responsiveness, sunken eyes, decreased skin turgor) 1, 4
  • If the infant is unable to keep down oral fluids 1
  • If diarrhea persists beyond 24-48 hours despite oral rehydration therapy 4
  • If there is blood in the stool or high fever 4

Remember that Pedialyte is preferable to other beverages like apple juice, Gatorade, or soft drinks, which should not be used for rehydration due to inappropriate electrolyte content 1.
