Prednisone for Acute Bronchitis with Wheezing: Not Recommended
Systemic corticosteroids, including prednisone, are not justified for acute bronchitis in otherwise healthy adults, even when wheezing is present. 1
Key Clinical Distinction: This is NOT Asthma
The critical first step is distinguishing acute bronchitis from conditions that DO benefit from steroids:
- Rule out asthma exacerbation - approximately one-third of patients diagnosed with "recurrent acute bronchitis" actually have undiagnosed asthma, which would benefit from prednisone 30-40 mg daily 2
- Rule out acute exacerbation of chronic bronchitis/COPD - these patients benefit from prednisone 40 mg daily for 5-7 days 1
- Rule out pneumonia - check for heart rate >100 bpm, respiratory rate >24 breaths/min, oral temperature >38°C, or focal lung findings 3
Why No Steroids for Acute Bronchitis?
- Acute bronchitis is viral in 89-95% of cases and follows a self-limited course resolving in approximately 10 days 1, 3
- French and European guidelines explicitly state systemic corticosteroids provide no benefit in acute bronchitis 1
- Purulent sputum does NOT indicate bacterial infection or justify steroid treatment 1
Management of Wheezing in Acute Bronchitis
For the wheezing component specifically:
- β2-agonist bronchodilators (albuterol) may be useful in select adult patients with wheezing accompanying the cough 3
- This addresses the bronchospasm symptomatically without the risks of systemic steroids 3
For the cough:
- Dextromethorphan 30-60 mg provides optimal cough suppression for bothersome dry cough 4
- First-generation sedating antihistamines may help with nocturnal cough 4
- Simple remedies like honey and lemon may be as effective as pharmacological treatments 4
Common Pitfall to Avoid
Do not prescribe steroids based on:
- Presence of wheezing alone (may be viral bronchospasm, not asthma) 1
- Purulent sputum (occurs in 89-95% of viral cases) 1, 3
- Duration of cough (viral bronchitis cough normally lasts 10-14 days) 3
When to Reconsider: Red Flags Suggesting Alternative Diagnosis
Reassess for steroid-responsive conditions if:
- Fever persists beyond 3 days (suggests bacterial superinfection or pneumonia) 3
- Cough persists beyond 3 weeks (consider asthma, COPD, pertussis) 3
- Patient has known COPD/chronic bronchitis with acute worsening 1
- Recurrent episodes suggest undiagnosed asthma 3
Patient Education
- Inform patients that cough typically lasts 10-14 days after the visit, even without treatment 3
- Explain that steroids expose them to unnecessary risks (hyperglycemia, weight gain, insomnia, immunosuppression) without providing benefit for viral bronchitis 1
- Patient satisfaction depends more on clear communication than whether medications are prescribed 3
