Medications for quick relief of the narrowed
bronchial
tubes caused by
asthma include short-acting
beta2-agonists. These medications relieve sudden
increases of symptoms (asthma attacks) quickly. However,
overuse may be harmful.
Overuse of short-acting beta2-agonists has
been associated with worsening asthma and increased risk of death.1 People with severe asthma usually are the ones at greatest
risk for illness and death from asthma. They may be taking higher doses of
short-acting beta2-agonists to control their symptoms
instead of increasing the use of anti-inflammatory medication such as inhaled
corticosteroids.
People who overuse short-acting
beta2-agonists may feel their asthma is under control
when, in fact, inflammation in the airways is becoming worse, putting them in
danger of a severe, life-threatening attack (status
asthmaticus).
Overuse:
May delay medical care and increase your chances
of having a severe asthma attack that can be life-threatening.
Can
decrease the future effectiveness of these medications.
Treats the
early narrowing of bronchial tubes without treating long-term inflammation,
which may result in permanent scarring.
Generally, you may need additional long-term treatment if you need to
use short-acting beta2-agonists more than 2 times a week
(except before exercise) or use more than one canister every 3 months.
If any of the above applies to you, see your health professional.
Frequent use of quick-relief medications may mean that your symptoms and
underlying inflammation are not well-controlled.
