Pneumocystis jiroveci is an important pathogen in patients undergoing SOT and HSCT. Universal prophylaxis is recommended for all adults and children with SOT and HSCT, considering that its use significantly reduces the occurrence and mortality associated with pneumonia by this agent. The drug of choice is cotrimoxazole (A1) three times a week, low-dose scheme, that has proved equally effective and better tolerated than the daily regimen and/or at high doses. Prophylaxis starts 7 to 14 days post transplant in SOT recipients and post-implant in HSCT, with an average duration of 6 months except in liver and lung transplant as in HSCT with significant degree of immunosuppression, that lasts for 1 year. Alternatives for prophylaxis are dapsone (B2), aerosolized pentamidine (B2) and atovaquone (C2).
