Prophylactic antimicrobial drugs are given to prevent infection in patients receiving chemotherapy.

Sulfamethoxazole and trimethoprim (Septra, Bactrim)

Sulfamethoxazole and trimethoprim inhibits bacterial growth by inhibiting synthesis of dihydrofolic acid. All immunocompromised patients can be given cotrimoxazole to prevent Pneumocystis carinii pneumonia (PCP).


Immunocompromised patients who do not tolerate cotrimoxazole due to myelosuppression may receive IV pentamidine to prevent Pneumocystis carinii pneumonia (PCP).
