Septra, (sulfamethoxazole and trimethoprim) norfloxacin: Trimethoprim/sulfa (septra (sulfamethoxazole and trimethoprim) or bactrim), norfloxacin, and Nitrofurantoin (macrobid) given in low dose each night before bed are the usual antibiotics used for frequently recurrent uti's. I do not prescribe Nitrofurantoin because of its potentially serious toxicities.
