Asthma: Do I Need Bronchodilators for Persistent Cough? - Pulmonology

More Info

---

Understanding asthma and its management can be quite complex, especially when symptoms like persistent cough are involved. Based on your description, it seems you have been dealing with a chronic cough for three years, with varying opinions from different pulmonologists regarding your diagnosis and treatment. Let’s break down your concerns and provide some clarity.

1. Do you have asthma?
The fact that you have a history of allergic rhinitis suggests that you may have a predisposition to respiratory issues, including asthma. However, the normal pulmonary function tests (PFTs) you’ve undergone indicate that your airways are functioning well at the time of testing. Asthma is characterized by reversible airway obstruction, which may not always be evident during a standard PFT, especially if you are not experiencing an exacerbation at the time of testing. It’s also possible that your cough could be due to other factors, such as post-nasal drip from your allergic rhinitis, chronic bronchitis, or even gastroesophageal reflux disease (GERD), which can also cause chronic cough.

2. Do you need to continue using bronchodilators?
Bronchodilators, particularly short-acting beta-agonists (SABAs), are typically used to relieve acute asthma symptoms by relaxing the muscles around the airways. If you have been using them for three years without significant improvement in your cough, it raises the question of whether they are the appropriate treatment for your condition. If your cough is primarily due to non-asthmatic causes, continuing bronchodilators may not be necessary. However, if you experience any wheezing, chest tightness, or difficulty breathing, it may indicate that you still have some degree of asthma or reactive airway disease, and bronchodilators could be beneficial.

3. What about the nasal spray?
The nasal spray you mentioned, likely a corticosteroid like Fluticasone (Flonase) or Budesonide (Rhinocort), is effective for managing allergic rhinitis. By controlling nasal inflammation, it may help reduce post-nasal drip, which can contribute to your cough. It’s essential to continue using this medication as prescribed, as it can help manage your allergy symptoms and potentially alleviate some of the cough.

4. What should you do next?
Given the conflicting opinions from different doctors, it may be beneficial to seek a second opinion from a specialist in allergy and immunology or a pulmonologist who has experience with complex cases. They may recommend additional testing, such as a methacholine challenge test, which can help determine if you have asthma that is not evident on standard PFTs.
5. Lifestyle and environmental factors:
Consider evaluating your environment for potential triggers of your cough. Common irritants include smoke, strong odors, cold air, and allergens like dust mites, pet dander, and pollen. Implementing measures to reduce exposure to these triggers can be beneficial.

In conclusion, while you may not have classic asthma based on your PFTs, your chronic cough warrants further investigation to determine its underlying cause. Continuing with the nasal spray is advisable, and the need for bronchodilators should be reassessed based on your symptoms and any new findings from further evaluations. Always communicate openly with your healthcare provider about your concerns and the effectiveness of your current treatment plan.
