What is the treatment for Pneumocystis jirovecii pneumonia?

Treat Pneumocystis jirovecii pneumonia with trimethoprim-sulfamethoxazole (Bactrim) as first-line therapy. This drug works by blocking folate synthesis in the organism, which is essential for its growth, and it has proven high efficacy against Pneumocystis. In most patients, high-dose TMP-SMX is given, usually starting intravenously in hospitals, and can be continued orally as the condition improves. If the pneumonia is severe and there is significant hypoxemia, adding corticosteroids improves outcomes and reduces mortality. If TMP-SMX cannot be used due to allergy or intolerance, alternatives include other regimens such as pentamidine or atovaquone, but these are less effective and used when TMP-SMX is not an option. Nitrofurantoin and azithromycin do not treat Pneumocystis infection, so they are not appropriate choices.
