Which statement about inhaled corticosteroid therapy in children is most accurate?

• A. Spacers are not usually necessary
• B. Spacers reduce systemic absorption and improve delivery
• C. Spacers are dangerous in children
• D. Spacers have no impact on dosing

Answer: (B)

Using a spacer with inhaled corticosteroids in children optimizes drug delivery to the lungs while lowering the amount that is swallowed and absorbed systemically. Kids often struggle to coordinate pressing the inhaler with inhaling deeply; a spacer provides a reservoir so the medication can be inhaled more slowly and deeply, increasing lung deposition. This means more of the drug acts where it’s needed and less stays in the mouth or is swallowed. The result is better asthma control at the same or even lower labeled dose, with fewer systemic side effects (like growth suppression) and fewer local complications (such as oral thrush and hoarseness) because overall systemic exposure is reduced. Spacers are particularly helpful for younger children and for those with imperfect inhaler technique, and they do influence dosing by delivering a greater fraction of the actuated dose to the lungs.
