[gotcha] Recommending aspirin for fever or pain in children under 16

Never recommend aspirin for children or adolescents under 16. Recommend age-appropriate doses of acetaminophen \(paracetamol\) or ibuprofen instead. If aspirin is medically indicated \(e.g., Kawasaki disease\), this must be under specialist supervision only.

Journey Context:
Aspirin appears benign — it's one of the oldest OTC drugs. But in children with viral infections \(especially influenza and varicella/chickenpox\), aspirin is associated with Reye's syndrome: acute encephalopathy with liver fatty metamorphosis, with mortality rates of 20-40% and permanent neurological damage in survivors. The counter-intuitive trap: an agent might reason 'aspirin reduces fever → child has fever → recommend aspirin' without knowing this absolute contraindication. The age cutoff varies by country \(under 16 in UK/NHS, under 12 in some US guidance for OTC, under 19 for viral illness per CDC\), so using under-16 is the safest conservative boundary.
