Treatment considerations in children aged 0-5 years.

Children in the first year of life have a less satisfactory response to treatment, but it is still worthwhile using bronchodilators by oral or nebulized route. In more severe cases, cromolyn or nebulized steroids are needed. Over 1 year, response to therapy is better and metered-dose inhalers with spacers become an easier way to deliver medication, although in severe acute attacks the nebulized route remains the preferred one.
