QVAR (beclomethasone dipropionate HFA) Inhalation Aerosol

How QVAR® Works to Treat Asthma

Asthma is a disease of chronic inflammation of both the large and small airways of the lungs. QVAR® is a small-particle inhaled corticosteroid (ICS) that can treat chronic inflammation caused by asthma.1 Because the particles of the ICS medication delivered by the QVAR® inhaler are smaller than some competing ICS inhalers, they can reach both the large and small airways of the lungs more effectively.2-9

Small-particle QVAR® reaches small airways*

Treating inflammation in the lungs is similar to treating inflammation from a rash on your skin. The medicine has to reach the inflamed areas in order to help. Because QVAR® particles are small, they can reach the small airways deep in your lungs.

After you inhale QVAR®, it gets into the cells in your airways and reduces the inflammation. By treating this underlying cause of asthma, you can reduce your risk of having asthma symptoms.1

Importance of treating small airways

Chronic inflammation can affect the small airways of the lungs.2 If the inflammation is not treated, these small airways may become permanently damaged.2,10 This inflammation may also be associated with asthma attacks and greater difficulty breathing.10

Small airway damage may occur in children with asthma.11 However, anti-inflammatory therapy can effectively control the airway inflammation and remodeling.12,13

Preventing the damage caused by chronic inflammation is important for patients with asthma. Using a long-term asthma control medicine like QVAR® that can reach both the large and small airways* to treat the inflammation of persistent asthma can help.

*The importance of how well QVAR® works due to better delivery of medication to the lungs has not been established.

QVAR® is indicated in the maintenance treatment of asthma as prophylactic therapy in patients 5 years of age or older. QVAR® is also indicated for asthma patients who require systemic corticosteroid administration, where adding QVAR® may reduce or eliminate the need for systemic corticosteroids.

Important Safety Information


QVAR® does not replace fast-acting (rescue) inhalers for sudden symptoms.

CAUTION: If you are switching from an oral corticosteroid to QVAR®, follow your doctor's instructions to avoid health risks when you stop using oral corticosteroids (See WARNINGS, Prescribing Information).

Inhaled corticosteroids may cause a reduction in growth rate. The long-term effect on final adult growth is unknown.

In clinical studies, common side effects included headache and pharyngitis.

Do not stop taking QVAR® abruptly without talking to your doctor.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
