Understand asthma symptoms, inflammation and attacks
Asthma causes inflammation in both the small and large airways—the branches that carry air into the lungs. Inflamed lungs may react to triggers like allergens or irritants such as exercise, cold air, secondhand smoke, mold or tiny dust mites that live in bedding and stuffed animals.1
When a person has an asthma attack (a period during which asthma symptoms appear or get worse), inflamed lungs experience “bronchospasm”—tightening of the bands of muscle surrounding the airways. This causes the lungs' airways to become narrow or blocked, making it hard to breathe.1
Common asthma symptoms include2:
- Coughing (often worse at night or early in the morning)
- Wheezing (like a whistling sound when you breathe)
- Chest tightness (like something is sitting on your chest)
- Shortness of breath (like you can’t catch your breath or get air out of your lungs)

Importance of treating asthma inflammation
For many people, asthma is a persistent condition. Even on days when you aren’t experiencing asthma symptoms, the underlying airway inflammation that causes asthma symptoms may still need to be treated. If asthma isn’t controlled, it can lead to more severe symptoms and even a greater risk of needing to go to the emergency room.2
How does QVAR® help treat asthma?
QVAR® is a type of daily asthma control medication called an ICS (inhaled corticosteroid). It works by helping to reduce airway inflammation. QVAR® can help prevent asthma symptoms, reduce the risk of asthma attacks and improve lung function for many people with asthma.3 Watch how QVAR®works.
