Cough is a normal protective mechanism. Chronic cough in children is different from that of adults and rarely are due to GERD, postnasal dripping or asthma. Treatment should be aimed at the specific causes and symptomatic treatment using the Over-The-Counter is not without disadvantage and is usually not effective. The efficacy of empiric uses of inhaled bronchodilator and corticosteroids may be due to the period effect, withdrawal of such therapy and and re-evaluation may be needed for the confirmation of diagnosis, to avoid the overdiagnosis and overtreatment of bronchial asthma using long-term corticosteroids.
