Treatment is aimed at avoiding known
allergens and respiratory irritants and controlling symptoms and
airway inflammation through medication. Allergens can sometimes be
identified by noting which substances cause an allergic reaction.
Allergy testing may also be helpful in
identifying allergens in patients with persistent asthma. Common
allergens include: pet dander, dust mites, cockroach allergens,
molds, and pollens. Common respiratory irritants include: tobacco
smoke, pollution, and fumes from burning wood or gas.
There are two basic kinds of
medication for the treatment of asthma:
- Long-term control
medications -- used on a regular
basis to prevent attacks, not for treatment during an attack.
- inhaled steroids (e.g.,
Azmacort, Vanceril, AeroBid, Flovent) prevent inflammation
- leukotriene inhibitors (e.g.,
Singulair, Accolate)
- long-acting bronchodilators
(e.g., famoterol, Serevent) help open airways
- cromolyn sodium (Intal) or
nedocromil sodium
- aminophylline or
theophylline (not used as frequently as in the past)
- combination of anti-inflammatory
and bronchodilator, using either separate inhalers or a
single inhaler (Advair Diskus)
- Quick relief (rescue)
medications -- used to relieve
symptoms during an attack.
- short-acting bronchodilators
(e.g., Proventil, Ventolin, Xopenex, and others)
- oral or intravenous
corticosteroids (e.g., prednisone, methylprednisolone)
stabilize severe episodes
People with mild asthma (infrequent
attacks) may use relief medication as needed. Those with persistent
asthma should take control medications on a regular basis to prevent
symptoms from occuring. A severe asthma attack requires a medical
evaluation and may require hospitalization, oxygen, and intravenous
medications.
A peak flow meter, a simple device to
measure lung volume, can be used at home to help you "see an attack
coming" and take the appropriate action, sometimes even before any
symptoms appear. If you are not monitoring asthma on a regular basis,
an attack can take you by surprise. Peak flow measurements can help
show when medication is needed, or other action needs to be taken.
Peak flow values of 50-80% of an individual's personal best indicate
a moderate asthma attack, while values below 50% indicate a severe
attack. |
