An inhaler is a device that can get asthma medicine directly into a person's lungs.
The medicine is a mist, spray, or powder that the person breathes in (inhales). In
the lungs, this medicine can go right to work, opening narrowed airways (breathing
tubes). When the tubes are open and clear, the person can breathe more easily, without
as much coughing or wheezing. Using an inhaler takes a little practice, but many kids
become experts at it. Spacers can make inhalers easier to use.
