In pediatric paracetamol dosing, what interval is commonly used between doses?

• A. Every 4-6 hours
• B. Every 6 hours
• C. Every 8 hours
• D. Every 12 hours

Answer: (A)

The interval is chosen to maintain relief while avoiding accumulation. In children, the analgesic and antipyretic effects of paracetamol typically last about 4 to 6 hours, so giving the next dose every 4 to 6 hours as needed provides continuous effect without stacking too closely. Doses are weight-based (commonly about 10–15 mg/kg per dose), and there’s a daily maximum plus a limit on how many doses can be given in 24 hours. Also be cautious not to use multiple products containing acetaminophen to prevent overdose. So the dosing rhythm used most often is every 4 to 6 hours.
