Hyperpyrexia in Infants Home Care

Home care for a fever in an infant includes:

  • Dress the infant in light, cotton clothes.
  • Provide plenty of liquids.
  • Encourage plenty of rest.
  • Acetaminophen for fever
    • Dosing is 10-15 mg per kilogram (5-7 mg per pound) of body weight every 4-6 hours, up to the adult dose.
  • Ibuprofen for fever
    • Dosing for children over 6 months of age is 7-10 mg per kilogram (4-5 mg per pound) of body weight every 6 hours, up to the adult dose.
  • Tepid baths for high fevers:
    • Tepid water is lukewarm or about 85-90 degrees F (29-32 C)
    • Sponge the body with tepid water.
    • No more than 20 to 30 minutes at a time
    • Increase the water temperature if the infant begins to shiver.

    • Alcohol is absorbed through the skin and can cause seizures.
  • Learn how to take your infant's temperature.
    • Measure the temperature every 2-4 hours.
