The only difference between Advair Diskus and Advair HFA is that Advair Diskus is a dry powder, while Advair HFA is delivered via propellant. Here, we'll refer to these medications simply as Advair.
As the number one best-selling asthma medication in the world, it's clear that Advair is a popular choice for people with asthma and/or COPD. Keep reading to find out more about the benefits of Advair.
Treats the Causes of Asthma Symptoms
Unlike rescue inhalers, which are used to immediately relieve the symptoms of an asthma attack, Advair is what's known as a maintenance inhaler.
This means that Advair works to treat the root causes of asthma symptoms like airway constriction and airway inflammation. Thus, people who use Advair as directed will experience fewer asthma attacks over time.
As anyone with asthma can attest, this is a valuable benefit that can improve one's quality of life in the long term. 
Prevents Flare-Ups or Worsening of COPD
Just as Advair works to prevent asthma attacks and symptoms over time, it can also be used to prevent COPD flare-ups (also known as COPD exacerbations) and the worsening of COPD.
This is true for both main forms of COPD, chronic bronchitis and emphysema. Chronic bronchitis involves swelling and irritation of the lungs' bronchial tubes, while emphysema involves swelling of and damage to the lungs' alveoli (air sacs).
Since COPD can shorten patients' lifespan if left untreated, Advair's ability to prevent COPD from getting worse can add years to the lives of those who need it. 
Available in Two Forms
To cater to each patient's needs, Advair is available in two convenient forms.
One is Advair HFA, a metered-dose inhaler (MDI) that delivers medication via a chemical propellant. Advair HFA is only approved to treat asthma.
Advair HFA can be a great choice for people with asthma who want an inhaler that delivers consistent, reliable doses.
The other form of Advair is Advair Diskus, a dry powder inhaler that uses no chemical propellant. Advair Diskus is approved to treat both asthma and COPD. 
Advair Diskus is an ideal choice for people who are sensitive to propellants or struggle to use the proper breathing technique necessary with MDIs.
