In certain conditions, medication needs to be delivered directly into the airways and the lungs, where it can be absorbed more rapidly and more effectively than oral therapy. The medication your doctor
prescribes will be delivered to your lungs as an aerosol mist, and is inhaled through a mask or mouthpiece. It is generated in a medication chamber, frequently known as a nebulizer.
Aerosol therapy or nebulizer drug therapy as it is often known, uses a much lower dose of your medicine than if you were to take it by mouth. This means that any possible side effects are reduced to a minimum.
