Fever in Children: Sorting Facts From Myths How do I give fever medications? continued

Should I use my child’s weight or age to find the right dose?

Always use weight if possible. Using age is not as accurate for estimating the correct dose since dosing by age assumes that your child is at an average weight for his or her age group. If a child is above or below the average weight of his or her age group, you could end up giving too high or too low a dose.2

How often should I give acetaminophen or ibuprofen?

  1. Give a dose acetaminophen or ibuprofen only as often as recommended
    • Wait at least 4 hours after giving acetaminophen to give a second dose
    • Wait at least 6 hours after giving ibuprofen to give a second dose
  2. Do not give more than the maximum number of doses that can be taken in a day
    • Give a dose of acetaminophen no more than 5 times in a day
    • Give a dose of ibuprofen no more than 4 times in a day
  3. Only give acetaminophen or ibuprofen IF NEEDED

MYTH: Kitchen spoons are accurate measuring utensils.

Do NOT use kitchen spoons. They are not measuring tools and will either give your child too much or too little medication. Use the medicine syringe or cup included with the medication to measure out the exact amount of medication to give. Ask your pharmacist to give you a measuring syringe or cup if you don’t already have one.
