About this trial
The usual first treatment for Pneumocystis jirovecii pneumonia (PCP) is an antibiotic called trimethoprim-sulfamethoxazole (TMP-SMX). However, some patients cannot take this medication because of allergies, side effects, or lack of response.
This study asks the question:
When TMP-SMX cannot be used, which alternative treatment for PCP provides the best balance of effectiveness and safety?
