What other antibiotics are there instead of Bactrim (sulfamethoxazole and trimethoprim) for Renal Infections? Experiencing kidney pain but on Bactrim (sulfamethoxazole and trimethoprim).

The antibiotic is generally selected based on the bacteria that may have been seen on the urine culture, the susceptibilities of the antibiotic to the bacteria and how much of the selected antibiotic is effectively delivered to the kidney and urine. .
