Sulfamethoxazole and trimethoprim combination is used to treat infections such as urinary tract infections, middle ear infections (otitis media), bronchitis, traveler's diarrhea, and shigellosis (bacillary dysentery).

This type of pneumonia occurs more commonly in patients whose immune systems are not working normally, such as cancer patients, transplant patients, and patients with acquired immune deficiency syndrome (AIDS).
