Helping your child use a metered-dose inhaler (MDI) with a mask spacer

Introduction

Key points

The medications used for asthma are often delivered through a metered-dose inhaler (MDI). Using an MDI with a mask spacer:

• Helps a young child get an accurate dose of medication.
• Delivers most of a measured dose of medication directly to your child's lungs.
• Can help keep your child's asthma symptoms under control and may help prevent long-term damage to his or her lungs.
• May prevent or decrease side effects of the medication.
• May let your child use less medicine than is found in a pill but get the same effect.
• May result in the medication working faster than a pill form.

What are a metered-dose inhaler and a mask spacer?

A metered-dose inhaler (MDI) is a handheld device that delivers a measured dose of medication directly to the lungs. The medication is usually in an aerosol form.

Using a spacer with an MDI is the most efficient way to get the most medication to your child's lungs. A spacer functions as a "holding" area for the medication before your child breathes in. Using a spacer with the MDI may improve the delivery of the medication and help your child if he or she has problems with releasing the medication and inhaling at the same time. A spacer should always be used with inhaled corticosteroids to avoid side effects.

A mask spacer is a spacer with a face mask at the end of the spacer. This is put over your child's mouth and nose. Mask spacers are used for young children who cannot use a spacer with a mouthpiece; they are usually needed for children from infancy through about age 5. However, many children about age 2 and older do not like the mask and should be encouraged to learn to use a standard spacer if they are willing to try it. Older children and adults who have problems using an MDI and spacer can also use a mask spacer.

Why should my child use a metered-dose inhaler with a mask spacer?

Using a metered-dose inhaler (MDI) with a mask spacer is helpful because:

• It provides a puff of medication in an accurate, measured dose.
• It can help keep your child's symptoms under control and may help prevent long-term damage to his or her lungs.
• When an MDI with a mask spacer is used effectively, most of the medication is delivered directly to your child's lungs and does not travel throughout the body. This may prevent or decrease side effects in the rest of your child's body.
• Your child 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.

How to help your child use a metered-dose inhaler with a mask spacer

Before using a metered-dose inhaler (MDI) with a mask spacer:

1. Talk with your health professional to be sure that you know how to use the MDI and mask spacer correctly. Be sure your child uses them exactly as your health professional has prescribed.
2. Depending on his or her age, teach your child how to check that he or she has the correct medication. If your child uses several inhalers, put a label on each one so that he or she knows which one to use at the right time. Consider using different colors or stickers to help your child see the difference between medications.
3. Check the label of the inhaler medication to see how many inhalations should be in the canister. If you and your child know how many breaths he or she can take, the inhaler can be replaced before it runs out. Learn how to test the canister to estimate how much medication is left. Your health professional or pharmacist can help you and your child with this.
