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 on more than 2 days a week (except
before exercise). Talk to your doctor if you are using your quick-relief
medicine this often. Frequent use of quick-relief medications may mean that
your symptoms and underlying inflammation are not well-controlled.
