Coughing is a complex reflex involving muscles and neural pathways. While typically a healthy response, persistent or chronic coughing can signal underlying health issues.[1]Cough is categorised into acute, subacute, and chronic types based on symptom duration. Initial evaluation in children includes thorough history, physical examination, chest X-ray, and spirometry. Referral to specialists is necessary for persistent chronic cough with red-flag symptoms like choking or recurrent infections.[2] Management focuses on treating the underlying cause; for instance, antibiotics for protracted bacterial bronchitis and inhaled medications for asthma. Paediatric guidelines do not recommend over-the-counter medicines (including antitussives, expectorants, mucolytics, and antihistamines) for acute cough due to insufficient evidence of effectiveness.[3]
