Identification

Identifying an asthma cough

The purpose of a cough is to remove foreign particles and bacteria to prevent a possible infection. There are two types of coughs: productive and nonproductive. When a cough is productive, it means that a noticeable amount of phlegm expelled. This enables the lungs to get rid of harmful substances.

Coughing in people with asthma can be helpful because it’s one of the body’s natural defense mechanisms. A productive asthmatic cough will expel phlegm and mucus from the lungs. In most cases of asthma, the cough is considered nonproductive. A nonproductive cough is a dry cough. It’s a response to an irritant that forces the bronchial tubes to spasm (or constrict). Swelling (inflammation) and constriction of the airways, which prompts this type of nonproductive cough, characterize asthma.

An asthma cough is also often accompanied by wheezing. This is a high-pitched whistling sound caused by a constricted airway.

Diagnosis

Diagnosis

Before you start an asthmatic cough treatment regimen, your doctor will order breathing tests to measure your lung function. You may need to have these test periodically to measure the effectiveness of any medications you’re taking.

According to the Mayo Clinic, these diagnostic tools are most effective in people ages 5 and older. Your doctor might also do allergy testing if they suspect allergens triggered your asthma cough.

Treatment

Treatment

Traditional treatments

Controller medications are often used to treat asthma. Inhaled corticosteroids help decrease lung inflammation, one of the causes of asthma cough. These are used on a long-term basis, unlike oral corticosteroids, which are used for short periods of time during severe flare-ups.

Doctors prescribe quick-relief inhalers to have on-hand in case of wheezing and coughing flare-ups. Most of these treatments fall into the class of short-acting beta-antagonists.

According to the American Academy of Allergy, Asthma, and Immunology, quick-relief inhalers are generally meant for use once or twice a week. Your doctor may also recommend them for use before exercise, or during an illness. Call your doctor if you find you rely on your quick-relief inhaler more often than recommended.

Long-term oral medications such as leukotriene modifiers may also relieve asthma cough. One such drug is montelukast (Singulair). Leukotriene modifiers work by treating asthma symptoms related to allergic rhinitis.
