Recommended Acetaminophen Dosage for 75-pound 11-year-old

For a 75-pound (34 kg) 11-year-old child, the recommended acetaminophen dose is 10-15 mg/kg every 4-6 hours, which equals 340-510 mg per dose, not to exceed 5 doses (2550 mg) in 24 hours. 1

Dosage Calculation

  • For children weighing 34 kg (75 pounds), the appropriate single dose range is:
    • Minimum: 10 mg/kg × 34 kg = 340 mg 1
    • Maximum: 15 mg/kg × 34 kg = 510 mg 1
  • Standard dosing interval: Every 4-6 hours as needed 1
  • Maximum daily doses: Do not exceed 5 doses in 24 hours 2, 1

Administration Guidelines

  • Acetaminophen can be administered in various forms (liquid, chewable tablets, regular tablets) 1
  • For children 11 years old, tablets or liquid formulations are appropriate based on the child's preference and ability to swallow pills 2
  • When using 325 mg tablets, 1 tablet (325 mg) falls within the recommended dose range 2, 1
  • When using 500 mg tablets, these would exceed the minimum recommended dose for this weight, so they should be avoided or split 2

Important Considerations

  • Accurate weight-based dosing is critical to ensure both efficacy and safety 1
  • Overdosing acetaminophen can lead to hepatotoxicity, which is a significant concern 3
  • Parents should record all dose times carefully to avoid accidentally exceeding the maximum recommended daily dose 4
  • Acetaminophen is considered one of the safest analgesics and antipyretics for children when used at appropriate doses 1, 5

Common Pitfalls to Avoid

  • Using adult formulations without proper dose adjustment can lead to overdosing 2, 3
  • Confusion may arise from different product labeling - always check the concentration of the specific acetaminophen product being used 3
  • Exceeding the recommended frequency (giving doses too close together) increases risk of toxicity 3
  • Administering multiple medications containing acetaminophen without realizing it (many combination cold/flu products contain acetaminophen) 3

Duration of Treatment

  • For fever or pain without medical supervision, acetaminophen should not be used for more than 3 consecutive days for fever or 5 days for pain 2
  • If symptoms persist beyond this timeframe, medical evaluation is recommended 2
