Using a metered-dose inhaler (MDI)

Why should I use a metered-dose inhaler?

Using a metered-dose inhaler (MDI) is beneficial because:

• It provides a puff of medication in an accurate, measured dose.
• It can help keep your symptoms under control and may help prevent long-term damage to your lungs.
• When an MDI is used effectively, most of the medication is delivered directly to your lungs and does not travel throughout the body. This may prevent or decrease side effects in the rest of your body.
• You may be able to use less medication than is found in a pill but get the same effect.
• The medication may work faster than a pill.
