Management of Dry Cough in Pulmonary Fibrosis
Initial Assessment and Management
- The European Respiratory Society recommends assessing for progression of underlying pulmonary fibrosis or complications from immunosuppressive treatment in patients with pulmonary fibrosis presenting with dry cough 4
- Evaluate for common comorbidities that may cause or worsen cough in pulmonary fibrosis patients, including gastroesophageal reflux disease (GERD) 5 and obstructive sleep apnea syndrome 6, 2
First-Line Treatment Options
- The European Respiratory Society recommends codeine as first-line therapy for dry cough in pulmonary fibrosis 1, 3
- If codeine is ineffective, low-dose oral corticosteroids can be prescribed for a limited period, with careful monitoring of efficacy and tolerance 1, 2
Important Considerations
- For patients with IPF and a negative workup for acid gastroesophageal reflux, proton pump inhibitor therapy should not be prescribed, as recommended by the American College of Chest Physicians 4
- For patients with pulmonary sarcoidosis, inhaled corticosteroids should not be routinely prescribed to treat chronic cough, according to the American College of Chest Physicians 4
- High-dose corticosteroids or thalidomide are poorly tolerated and inadvisable for long-term management, as stated by the European Respiratory Society 1, 2
Treatment for Refractory Cough
- Opiates may be recommended for symptom control in a palliative care setting, with reassessment of benefits and risks at 1 week and then monthly before continuing, as suggested by the American College of Chest Physicians 4, 5
- Low-dose morphine derivatives (<30 mg oral morphine equivalents daily) may be used with careful monitoring of side effects, as recommended by the European Respiratory Society 1, 3
- Consider therapies recommended for unexplained chronic cough, including gabapentin or pregabalin (neuromodulators) 5 and multimodality speech pathology therapy 4, 5
Monitoring and Follow-up
- Regular clinical visits and pulmonary function tests (including FVC) every 3-6 months are recommended by the European Respiratory Society 1, 3
- Monitor for progressive increase in dyspnea 3, progressive decrease in FVC or DLCO 3, and worsening of signs on computed tomography 1, 3
Treatment of Comorbidities
- Treatments that work for unexplained chronic cough have not been extensively studied specifically in ILD-associated cough, but may be considered, as noted by the American College of Chest Physicians 5
