Many patients have trouble using dry powder inhalers
Many patients have trouble using dry powder inhalers... Asmanex, Foradil, Pulmicort Flexhaler, Spiriva, and Advair, Flovent or Serevent Diskus.
Up to 30% of patients don't use these correctly. Some even swallow Foradil or Spiriva caps instead of putting them in the inhaler.
Dry powder inhalers don't require timing of the inhalation like metered-dose inhalers. But patients do need to inhale forcefully...and the device can be more complicated to use.
