urinary tract infection
"Septra DS worked wonderful this time I am only on day 2 with 5 more days to go. I have however taken this and Bactrim DS before. I am quite sensitive to antibiotics but tolerate these well. I usually ask for Bactrim DS due to tolerating it well so that is what MD prescribed. i also take metformin and lotensin and they seem to work fine with this med though i take them at least 3 hours from each other"
