When you use inhaledasthmamedicine, you usually use a device that delivers the medicine directly to your lungs. Different types of delivery systems are available. And one type may be more suitable for certain people, age groups, or medicine than another. The following table describes how asthma medicines may be delivered.
Doctors recommend the use of a spacer with a metered-dose inhaler (MDI). The spacer is attached to the MDI. A spacer may deliver the medicine to your child's lungs better than an inhaler alone and, for many people, is easier to use than an MDI alone. Using a spacer with inhaled corticosteroid medicine can help reduce their side effects and result in less use of oral corticosteroid medicine.
A spacer is recommended for children age 5 and older.
A spacer and a face mask are recommended for children younger than 5.
Using a spacer with an MDI may be just as effective as and less expensive than a nebulizer and can reduce the risk of an overdose.
If you don't use a spacer, you need to trigger a puff of medicine and inhale at the same time.
