Ibuprofen for children — frequently asked
How is a child's ibuprofen dose calculated by weight?+
Paediatric ibuprofen is dosed at about 10 mg per kg of body weight per dose, every 6–8 hours as needed, with a maximum of 40 mg/kg (and usually no more than 4 doses) in 24 hours. The calculator converts that mg dose into millilitres for the syrup strength you select.
Is ibuprofen dosed by age or weight?+
Weight gives a far more accurate paediatric dose than age. Always dose by the child's current weight where possible.
At what age can a child take ibuprofen?+
Ibuprofen is generally not recommended for babies under 3 months or under 5–6 kg, and should be avoided in dehydration, chickenpox, or known kidney problems. For young infants, check with your paediatrician and consider paracetamol instead.
Can I give ibuprofen and paracetamol together?+
They can sometimes be alternated under medical advice for a high fever, but they should not be given at the same time without a doctor's guidance. Never exceed the maximum dose of either medicine.
When should I seek urgent care instead?+
Seek urgent care for a baby under 3 months with fever, or any child with breathing difficulty, severe drowsiness, repeated vomiting, dehydration, a seizure, or suspected overdose. This tool is informational and does not replace a clinician.
