Which statement describes when antibiotics are indicated for acute bronchitis?

• A. Always initiate antibiotics
• B. Never use antibiotics
• C. Antibiotics are indicated if symptoms persist >7 days, or in elderly, smokers/COPD, or immunocompromised
• D. Antibiotics only for patients under age 5

Answer: (C)

Acute bronchitis is typically viral, so antibiotics aren’t routinely helpful and should be avoided to prevent unnecessary side effects and antibiotic resistance. The best statement reflects a targeted approach: antibiotics are considered when symptoms persist beyond about a week or in patients at higher risk—older adults, smokers with COPD or other lung disease, or those who are immunocompromised. In these groups the chance of bacterial involvement or progression to a more serious infection is greater, so the potential benefit of antibiotics may outweigh the risks. For otherwise healthy individuals with classic viral bronchitis, supportive care is the appropriate path. The other options are too absolute and don’t account for risk factors or duration of symptoms.
