Frequently asked questions
Can I alternate ibuprofen and paracetamol?
Yes, alternating can provide more constant pain/fever relief. Keep separate dosing schedules and never give both at the same time without specific medical advice. Each medication has its own daily maximum that must not be exceeded.
Why avoid ibuprofen in chickenpox?
NSAIDs including ibuprofen have been associated with increased risk of severe skin and soft-tissue bacterial complications (necrotizing fasciitis) in children with varicella infection. Use paracetamol instead during chickenpox.
Is ibuprofen better than paracetamol for fever?
Both reduce fever effectively. Ibuprofen has slightly longer duration (6–8h vs 4–6h) and additional anti-inflammatory action useful in some conditions. Paracetamol has fewer contraindications. Choice depends on the child's specific situation.
My child has asthma — can I give ibuprofen?
Most children with asthma tolerate ibuprofen safely. A minority experience NSAID-induced bronchospasm. If your child has had problems with NSAIDs before, or has aspirin-exacerbated respiratory disease, avoid ibuprofen. Discuss with your pediatrician.
