Cough-Variant Asthma is a condition affecting the trachea and bronchial tubes, where the primary symptom is a persistent cough. The duration of the cough can vary, ranging from a few weeks to several years or even more than ten years. However, when the cough persists for an extended period, it can significantly impact daily life, underscoring the importance of seeking timely and appropriate treatment. This article explains what Cough-Variant Asthma is and its characteristics.

If a persistent cough continues for approximately 8 weeks or more even after recovering from a cold, there may be suspicion of Cough-Variant Asthma. Similar to bronchial asthma, it involves an exaggerated response of the airways and bronchial tubes (the passage for air) to various stimuli, leading to narrowing, inflammation, and the presence of coughing. The causes can be related to one’s lifestyle, such as exposure to house dust, mold, pet dander, pollen, tobacco, or alcohol.
It is often observed to develop alongside a cold, and when a cough lingers after a cold, the possibility of Cough-Variant Asthma is considered. It has been reported to be more prevalent among individuals with allergic tendencies, and there is a recent trend of increasing numbers of affected patients.
If a cough subsides within approximately 2 weeks, it is often attributed to a common cold. However, if the symptoms mentioned above persist for about 8 weeks, it is advisable to consider seeking medical consultation from a respiratory or allergy specialist. In cases where the symptoms are severe, it is necessary to promptly seek medical attention without hesitation.
For individuals already receiving treatment for cough-variant asthma, it is recommended to consider seeking medical consultation if symptoms worsen or if the use of medication during episodes does not improve the condition.
At eHealth Clinic’s Allergy Department, we provide diagnosis and treatment for cough-variant asthma. As the causes of cough-variant asthma can vary among individuals, we conduct allergy tests to determine appropriate treatment and strategies. Please feel free to consult with us.
The treatment of cough-variant asthma primarily involves medication therapy, similar to traditional asthma treatment. Over-the-counter cold medications are ineffective since cough-variant asthma is not caused by a common cold. Additionally, it is crucial to maintain a conducive living environment by avoiding secondhand smoke and keeping the living space clean to prevent exacerbation of symptoms.
For the treatment of cough-variant asthma, bronchodilators are used. Bronchodilators are medications that widen the airways (the passages through which air flows) and facilitate easier breathing. In some cases, inhaled corticosteroids may also be prescribed as necessary. Inhaled corticosteroids help reduce inflammation in the airways and bronchi. Unlike oral steroids, inhaled corticosteroids directly target the airways and bronchi, minimizing systemic side effects.
If the cough subsides with this treatment, it is important not to discontinue the therapy based on personal judgment, as there is a possibility of recurrence. Therefore, it is crucial to continue the treatment for several months as per the physician’s instructions.
Asthma cough can be worsened by lifestyle habits and environmental factors. Therefore, it is important to be mindful of avoiding triggers that can worsen symptoms in your daily life.

Without proper treatment, cough-variant asthma can carry the risk of recurrence or progression to asthma. Therefore, it’s important not to discontinue treatment based solely on improvement of symptoms through self-assessment. If you have any concerns, don’t hesitate to consult with a physician.
