About two weeks ago, I developed a UTI and was put on a 3-day course of Bactrim, which seemed to have worked, judging by the disappearance of symptoms.
Yesterday, though, it became obvious to me that the UTI had returned (or I guess I could have developed a new one). I went back to the doctor and this time was put on a 5-day course of Cipro and my urine specimen was sent off to be cultured.
While Googling around for info on UTI pathogens, I found this, which concludes that E. Coli is the most common UTI pathogen and Cipro should be the drug of choice of UTIs. (The article appeared in the Central Africa Journal of Medicine. I have no idea if that’s relevant or not.)
Anyhoo, why would a doctor choose Bactrim over Cipro? The cost was about the same.
