Introducing the concept of loss of corticosteroid credit in asthma.

ABSTRACT

The widespread use of systemic corticosteroids (SCS) in asthma is associated with significant comorbidities and mortality. A dose-response relationship for cumulative SCS exposure with most adverse outcomes began at cumulative exposures of 1.0-<2.5 g, equivalent to four lifetime SCS courses. The purpose of creating the SCS credit concept was to increase awareness of the risks of SCS exposure and to promote better therapeutic alternatives. Consuming the lifetime SCS credit of 1.5 g/yr significantly increased morbidity and mortality.
