Is it appropriate to give a short course of systemic corticosteroids to a healthy 17‑year‑old with acute bronchitis?

No, Do Not Use Systemic Corticosteroids for Acute Bronchitis in a 17-Year-Old

Corticosteroids should not be used routinely in the management of acute bronchitis in otherwise healthy adolescents, as there is no evidence of benefit and potential for harm. 1, 2

Evidence Against Steroid Use in Acute Bronchitis

Lack of Efficacy

• The most recent high-quality guideline (CHEST 2020) explicitly recommends against routine prescription of oral corticosteroids for immunocompetent adult outpatients with acute bronchitis. 1
• There is no supporting evidence for steroid use in patients with acute bronchitis, and the evidence actually argues against their use. 2
• Acute uncomplicated bronchitis is typically a self-limited viral infection of the large airways that does not respond to corticosteroid therapy. 1

Potential Harms

Even short courses of systemic corticosteroids carry risks that outweigh any theoretical benefits in acute bronchitis:

• Hyperglycemia occurs in approximately 38 more cases per 1000 patients treated (moderate certainty evidence). 3
• Sleep disturbances increase by 15 more cases per 1000 patients (moderate certainty evidence). 3
• Gastrointestinal bleeding risk increases by 13 more cases per 1000 patients (low certainty evidence). 3
• Additional adverse effects include elevated blood pressure, mood disturbance, increased risk of sepsis, fracture, and venous thromboembolism. 2

Important Clinical Distinctions

When Steroids ARE Indicated (Not Acute Bronchitis)

Be careful to distinguish acute bronchitis from conditions that DO benefit from corticosteroids:

• Asthma exacerbations: Short courses of 40-60 mg prednisone for 5-10 days are appropriate. 1
• COPD exacerbations with bacterial infection signs (increased sputum purulence plus increased dyspnea and/or sputum volume): A 10-15 day course of systemic corticosteroids is recommended. 1
• Croup or bronchiolitis in younger children: These are distinct conditions with different evidence bases. 1

Key Pitfall to Avoid

The most common error is misdiagnosing asthma exacerbation or COPD exacerbation as "acute bronchitis." 1 If the patient has:

• History of asthma or reactive airways disease
• Wheezing responsive to bronchodilators
• Known COPD with acute worsening

Then reconsider the diagnosis—these conditions may warrant corticosteroids, but simple acute bronchitis in a healthy 17-year-old does not. 1

Recommended Management Instead

For a healthy 17-year-old with acute bronchitis:

• Reassurance and symptomatic treatment only. 1
• No antibiotics unless pneumonia is suspected or bacterial infection becomes likely with worsening symptoms. 1
• Reassessment if symptoms persist or worsen to rule out alternative diagnoses like pneumonia, asthma, or other conditions. 1
