Inhalers dispense medications that are frequently used to treat conditions where it is beneficial to apply medication directly and deeply into the lungs. These conditions include:

• Asthma. A condition where the airways become blocked and/or narrowed, causing shortness of breath and difficulty breathing. Asthma can be triggered by environment factors, including allergens, cold air and exercise. Inhalers can deliver medication rapidly to the airways, quickly relieving an asthma attack.
  
  

  

• Chronic obstructive pulmonary disease (COPD). Condition whereby airflow in and out of the lungs is disrupted. Includes emphysema and chronic bronchitis.

• Allergies. Some allergies cause symptoms to appear in the lungs and airways (such as coughing and shortness of breath). Inhalers can quickly deliver medication to treat these symptoms.
