What is the management of fever and pain in children under five years old?

Management of Fever and Pain in Children Under Five Years Old

For children under five years old, acetaminophen (10-15 mg/kg every 4-6 hours) or ibuprofen (5-10 mg/kg every 6-8 hours) should be used for fever and pain management, with ibuprofen showing superior fever reduction while both medications have similar safety profiles when used appropriately. 1, 2

First-Line Medications

• Acetaminophen (paracetamol) and ibuprofen are the most widely recommended medications for managing fever and pain in children under five years old 1, 2
• Acetaminophen dosing: 10-15 mg/kg every 4-6 hours, not exceeding 4 doses in 24 hours 3
• Ibuprofen dosing: 5-10 mg/kg every 6-8 hours, not exceeding 40 mg/kg/day 4
• Aspirin should NEVER be used for fever control in children due to the risk of Reye's syndrome 1, 3

Comparative Efficacy

• Ibuprofen (5-10 mg/kg) reduces temperature more effectively than acetaminophen (10-15 mg/kg) at 2,4, and 6 hours after treatment 5
• For pain relief, both medications show comparable efficacy in treating moderate to severe pain 2, 5
• Ibuprofen has the advantage of less frequent dosing (every 6-8 hours vs. every 4 hours for acetaminophen) 4

Safety Considerations

• Both medications have similar safety profiles when used at appropriate doses 2, 5
• In overdose situations, acetaminophen toxicity is reached earlier and is more severe compared to ibuprofen overdose 4
• Single ingestions of more than ten times the recommended dose of acetaminophen are potentially hepatotoxic 3
• Exposures greater than 140 mg/kg/day of acetaminophen for several days carry risk of serious toxicity 3

Treatment Approach Algorithm

1. Initial assessment:

   • Determine severity of fever and associated symptoms 1
   • Assess for signs of serious illness requiring medical attention 1

2. For mild to moderate fever (38-39°C) with discomfort:

   • Provide antipyretics (acetaminophen or ibuprofen) 1
   • Ensure adequate hydration 1
   • Monitor for improvement of symptoms 1

3. For higher fever (>39°C) or significant pain:

   • Consider ibuprofen for its superior antipyretic effect 5
   • Monitor response within 4-6 hours 1
   • If inadequate response, alternate with the other medication (with appropriate timing) 6

4. When to seek medical attention:

   • Fever in infants under 3 months of age 1
   • Fever persisting >48 hours 1
   • Signs of respiratory distress, dehydration, altered consciousness 1
   • Unusual irritability or lethargy 1

Common Pitfalls to Avoid

• Treating fever without discomfort - fever itself may be beneficial in fighting infection and does not require treatment if the child is comfortable 6
• Focusing solely on normalizing body temperature rather than improving overall comfort 6
• Using aspirin for fever control in children 1, 3
• Administering incorrect dosages - always calculate based on weight, not age 3
• Combining medications without proper timing, which can lead to dosing errors 6
• Underestimating the importance of hydration during febrile illness 1

Special Considerations for Infants

• Children under 1 year of age should always be evaluated by a physician due to higher risk of complications 1
• Infants under 3 months with fever require immediate medical attention 1
• Dosing must be carefully calculated based on weight for young infants 3
