Prophylaxis for Pneumocystisjiroveci (a normally harmless commensal organism) is most important, as this causes a common, preventable, serious infection. In patients with CD4 counts of less than 200/μL, prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMX; Bactrim) has been shown to prevent Pneumocystis pneumonia (PCP).
