Inhaled corticosteroids (ICSs) are the most effective medications available for patients with persistent asthma of all severities and currently are recommended as the preferred asthma controller therapy by the National Heart, Lung and Blood Institute. Nevertheless, lingering concerns about potential adverse systemic effects of ICSs contribute to their underuse. This review discusses the safety of ICSs with respect to potential systemic effects of most concern to physicians and patients. ⋯ ICSs have minimal systemic effects in most patients when taken at recommended doses. The benefits of ICS therapy clearly outweigh the risks of uncontrolled asthma, and ICSs should be prescribed routinely as first-line therapy for children and adults with persistent disease.
