What is the maximum single dose of acetaminophen for pediatric pain management?

• A. 1 g
• B. 750 mg
• C. 500 mg
• D. 2 g

Answer: (A)

Dosing children with acetaminophen is weight-based, and there is a safety cap to prevent liver injury. The standard per-dose guidance is 10–15 mg per kilogram of body weight, given every 4–6 hours as needed, with a maximum of 1,000 mg per single dose. That cap means, regardless of weight, you would never give more than 1 gram in one dose. So the maximum single dose for pediatric pain management is 1,000 mg. The other amounts are simply smaller single doses or exceed the safe per-dose limit (a 2,000 mg dose would risk serious hepatotoxicity; 500 mg and 750 mg are valid but not the maximum allowed per dose).
