Bronchospasm (Adult)

Front view of man showing respiratory system. Inset shows inflamed airway.

Bronchospasm occurs when the airways (bronchial tubes) go into spasm and contract. This makes it hard to breathe and causes wheezing (a high-pitched whistling sound). Bronchospasm can also cause frequent coughing without wheezing.

Bronchospasm is due to irritation, inflammation, or allergic reaction of the airways. People with asthma get bronchospasm. However, not everyone with bronchospasm has asthma.

Being exposed to harmful fumes, a recent case of bronchitis, exercise, or a flare-up of chronic obstructive pulmonary disease (COPD) may cause the airways to spasm. An episode of bronchospasm may last 7 to 14 days. Medicine may be prescribed to relax the airways and prevent wheezing. Antibiotics will be prescribed only if your healthcare provider thinks there is a bacterial infection. Antibiotics do not help a viral infection.

Home care

  • Drink lots of water or other fluids (at least 10 glasses a day) during an attack. This will loosen lung secretions and make it easier to breathe. If you have heart or kidney disease, check with your doctor before you drink extra fluids.

  • Take prescribed medicine exactly at the times advised. If you take an inhaled medicine to help with breathing, don't use it more than once every 4 hours, unless told to do so. If prescribed an antibiotic or prednisone, take all of the medicine, even if you are feeling better after a few days.

  • Don't smoke. Also avoid being exposed to secondhand smoke.

  • If you were given an inhaler, use it exactly as directed. If you need to use it more often than prescribed, your condition may be getting worse. Contact your healthcare provider.

Follow-up care

Follow up with your healthcare provider, or as advised.

If you are age 65 or older, have a chronic lung disease or condition that affects your immune system, or you smoke, ask your healthcare provider about getting a pneumococcal vaccine, as well as a yearly flu shot (influenza vaccine).
