Mild to moderately ill patients with CAP may be treated entirely via the oral route, on either an inpatient or outpatient basis. The duration of therapy for uncomplicated CAP is usually 5 days. [25, 19] The duration of therapy for CAP due to suspected or proven Pseudomonas or MRSA should be 7 days. Patients should be afebrile for 48-72 hours and have no signs of instability before antibiotic therapy is stopped. The duration of therapy may need to be increased if the initial empiric therapy has no activity against the specific pathogen or if the pneumonia is complicated by extrapulmonary infection. [25]
