Breathing Problems: Using a Metered-Dose Inhaler

Diseases affecting the lungs—such as asthma, emphysema, chronic bronchitis, and chronic obstructive pulmonary disease (COPD)—share many of the same medicines. These medicines are often delivered through a metered-dose inhaler (MDI).

Using an MDI:

  • Delivers most of a measured dose of medicine directly to your lungs.
  • Can help keep your symptoms under control and minimize long-term damage to your lungs.
  • May prevent or reduce side effects of the medicine.
  • May let you 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.
