- Viral illness
- Cold weather
- Gastroesophageal reflux disease (GERD)
- Sulfites used in dried fruits and wine
- Medications, such as aspirin , ibuprofen , and beta-blockers
Exposure to irritants or allergens, including:
- Cigarette smoke
- Smoke from a wood-burning stove
- Pet dander
- Mold and mildew
- Smog or air pollution
- Perfumed products
- Regularly breathing in cigarette smoke (including second-hand smoke)
- Regularly breathing in industrial or agricultural chemicals
- A family member who has asthma
- History of multiple respiratory infections during childhood
- Being overweight
- History of wheezing or asthma as a child
- Having allergies
- Your mother smoked during pregnancy
- Tightness in the chest
- Trouble breathing
- Shortness of breath
- Chest pain
- Limited exercise tolerance, difficulty keeping up with peers
- Peak flow examination—blowing quickly and forcefully into a special instrument that measures your output of air
- Pulmonary function tests (PFTs)—breathing into a machine that records information about the function of your lungs
- Reversibility testing—tests for relief of airflow obstruction when medicines such as albuterol or ipratropium are given.
- Bronchoprovocation tests—lung function tests performed after exposure to methacholine to stimulate asthma; can help to confirm asthma in unclear cases
- Exhaled nitric oxide (a marker of airway inflammation)—to help monitor asthma control
- Avoidance of allergens and irritants and control of contributing factors (such as gastroesophageal reflux and sinusitis )
- Regular assessment and monitoring
- Inhaled corticosteroid—used daily to reduce inflammation in your airways
Long-acting beta agonists—(such as inhaled
) used daily to prevent asthma attacks. In most cases, prescribed with an inhaled corticosteroid
- May increase the risk of asthma-related death, intubation (putting a tube in the windpipe to breath), and hospitalization—If you have any concerns, talk to your doctor.
- Cromolyn sodium or nedocromil sodium inhaler—used daily to prevent asthma flare-ups or to prevent exercise-induced symptoms
- Zafirlukast, zileuton, and montelukast—taken daily to help prevent asthma attacks
- Omalizumab (Xolair)—a monoclonal antibody against immunoglobulin E (IgE), given as an injection under the skin, used along with other medications for patients with harder to control asthma
- Theophylline—taken daily to help prevent asthma attacks, not as commonly used because of interactions with other drugs
- Quick-acting beta agonists—(such as inhaled albuterol , xopenex ) relax your airways so that they become wider again, may also be used to avoid exercise-induced asthma attacks
- Anticholinergic agents—inhaled medications, such as ipratropium , that function as a bronchodilator, typically only used in an emergency setting
Corticosteroids—pills, injections, or IV medications given to treat acute flare-up of symptoms
- Pills may be taken for a longer period of time. They may also be recommended to help control asthma if you have severe asthma that isn't responding to other treatments.
- Avoid outside activities if there are high levels of air pollution, pollen, or mold spores.
- Keep your windows closed during seasons with high pollen or mold spores. Air conditioning may help filter out allergens during warm seasons.
- Consider getting a portable HEPA unit air cleaner to use in sleeping areas.
- Consider getting HEPA filters for your heating/cooling system and your vacuum cleaner.
- Have someone else vacuum for you. Avoid a room that has been freshly vacuumed. If you do vacuum, use a dust mask.
- Keep the humidity down in your house. This may help prevent the growth of mold.
- Treat allergies and sinusitis as recommended.
- Avoid strong chemicals or odors like perfume.
- Avoid strenuous outdoor exercise during days with high air pollution, a high pollen count, or a high ozone level.
- Get a yearly seasonal flu shot . Colds and flus can exacerbate asthma.
- Don't smoke. If you are pregnant, it is very important that you do not smoke.
- Avoid secondhand smoke. Do not allow anyone to smoke in your home.
- Don't use a wood-burning stove or fireplace, including unvented gas fireplaces.
- If cold weather triggers your asthma, avoid strenuous activities in cold weather. If you must, use a scarf or mask to warm the air before it reaches your lungs.
- An appropriate level of exercise for you
- Ways to track your asthma to help identify and treat flare-ups right away.
- Your work, hobbies, and home activities to see if any of these may be causing or worsening your asthma.
