Treatment Approach for Chronic Cough with Wheezing

Initial Assessment

• The American Thoracic Society recommends ruling out serious conditions like pneumonia or pulmonary embolism that may present with cough and wheezing 3
• The American College of Chest Physicians suggests checking if the patient is taking an ACE inhibitor, which can cause chronic cough - if so, discontinue and replace with another medication 1, 4
• Smoking cessation should be strongly advised as it can resolve cough symptoms within 4 weeks, according to the American College of Chest Physicians 5, 4
• A chest radiograph should be obtained to rule out significant pathology, as recommended by the American Thoracic Society 6

Treatment Algorithm

Step 1: Asthma Treatment

• The American College of Chest Physicians recommends initiating treatment with inhaled corticosteroids (ICS) combined with long-acting β-agonists (LABA) such as fluticasone/salmeterol twice daily for patients with chronic cough and wheezing 2
• The American Thoracic Society suggests monitoring for response within 2-4 weeks 1

Step 2: If Incomplete Response, Add Treatment for Upper Airway Cough Syndrome (UACS)

• The American College of Chest Physicians recommends adding a first-generation antihistamine/decongestant combination for patients with incomplete response to asthma treatment 6, 7
• The American Thoracic Society suggests expecting some improvement within 1-2 weeks, though complete resolution may take several weeks 8

Step 3: If Still Inadequate Response, Address Gastroesophageal Reflux Disease (GERD)

• The American College of Chest Physicians recommends initiating empiric treatment for GERD with proton pump inhibitors for patients with inadequate response to previous treatments 1, 9
• The American Thoracic Society suggests continuing previous treatments as cough is often multifactorial 10, 5

Special Considerations

• The American Thoracic Society recommends considering bronchoprovocation challenge (BPC) to confirm asthma diagnosis if spirometry is available and does not show reversible airflow obstruction 1, 2
• The American College of Chest Physicians suggests considering induced sputum testing for eosinophils or an empiric trial of corticosteroids for patients with suspected non-asthmatic eosinophilic bronchitis (NAEB) 1, 7

When to Consider Referral

• The American College of Chest Physicians recommends considering referral if cough persists despite sequential trials of therapy for common causes 1, 7
