Frequently asked questions
How often can I give my child paracetamol?
Every 4–6 hours as needed for fever or pain, up to 4 doses in 24 hours. Do not exceed the maximum daily dose (60 mg/kg/day, capped at 4 g for adolescents).
Can I give paracetamol to a baby under 3 months?
Generally not without specific medical guidance. Paracetamol in young infants requires careful weight-based dosing and clinical assessment. Check with your pediatrician or call NHS 111 / equivalent first.
What if my child's weight is between two recommended doses?
Use weight-based calculation (15 mg/kg) and round to the nearest 0.5 mL of suspension. The calculator above gives the precise dose. Never use age-based dosing alone — children of the same age vary substantially in weight.
Is paracetamol safer than ibuprofen for children?
Both are commonly used and considered safe at correct doses. Paracetamol is preferred under 3 months and in dehydration or vomiting. Ibuprofen has anti-inflammatory effects useful for some conditions but should be avoided in chickenpox, dehydration, or kidney issues. Consult your pharmacist about the best option.
