The technique that is most often recommended by The Asthma Center specialists involves the use of an inhaler with a spacer device (holding chamber). Here the MDI is attached to a spacer device, and you exhale completely before inserting the mouthpiece of the spacer into your mouth.
When the MDI is activated, begin to breathe in slowly. The rate of flow of medication sprayed into the holding chamber slows down, and it can be completely inhaled even if your coordination is not perfect. Additional benefits include a much lower incidence of sore throats due to reduced impact of medicated spray on the back of the throat, decreased hoarseness, decreased medication taste, and less of a chance to develop mouth and throat fungal infections for those using inhaled corticosteroids.
