Key points
The medicines 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 medicine.
- Delivers most of a measured dose of medicine directly to your child's lungs.
- Can help keep your child's asthma symptoms under control and allow your child to live an active life.
- May prevent or reduce side effects of the medicine.
- May let your child use less medicine than is found in a pill but get the same effect.
- May result in the medicine working faster than a pill form.
