Correct use of metered-dose inhalers and spacer devices

In addition to prescribing an appropriate drug regimen, physicians must carefully educate asthmatic patients. For 10 million such patients in the United States as well as millions more around the world, successful education is critical to quality of life and can save lives. Responsible patients who understand that asthma attacks are preventable and who use their medications correctly usually have a gratifying response to treatment. Of special importance is the optimal use of aerosolized drugs, most often given by a metered-dose inhaler plus spacer device.
