What is the recommended medical management for a lung abscess?

• A. Broad-spectrum antibiotics for 4-6 weeks plus chest physiotherapy
• B. Short course antibiotics for 3-5 days
• C. Antivirals
• D. No antibiotics, observation only

Answer: (A)

Treating a lung abscess relies on eradicating the infection with antibiotics that cover the usual culprits, especially oral anaerobes, for a prolonged period. The best approach is broad-spectrum antibiotics directed at both aerobic and anaerobic bacteria and continued for about 4 to 6 weeks, with adjustments based on clinical response and imaging. Chest physiotherapy can be a helpful adjunct to improve clearance of secretions and facilitate drainage from the cavity, supporting recovery as antibiotics work to eradicate the infection. Drainage or surgical intervention is reserved for cases that do not respond to antibiotics or involve large or complicated abscesses. Short antibiotic courses are inadequate because the infection is slow to resolve and anaerobic organisms are often involved. Antivirals target viruses, not bacteria, and observing without antibiotics ignores the risk of progression to sepsis or spreading infection.
