Temporary increased dose of inhaled corticosteroids in yellow zone, does it work?

There are limited data as how to manage the "yellow zone" in children with asthma. Although increasing the dose of inhaled corticosteroids (ICSs) has been practiced by some providers, the efficacy and safety of this strategy remain unclear. This review presents the existing data for use of adjustable dose of ICSs for prevention of asthma exacerbation in children in yellow zone. The current evidence does not support increasing the dose at early signs of loss of asthma control to prevent asthma exacerbation in children. Well-designed clinical trials are needed to identify potential benefits of this strategy.
