Cephalexin
"I came down with a bad urinary tract infection 3 days ago and I was put on Bactrim twice a day. I have had several UTIs before and it has worked in the past. However, this time around 2 days after the medicine I wasn't seeing improvements so I went back to the doctor and switched to cephalexin. Last night was my first dose and I woke up this morning feeling completely normal again. I like to read these reviews so I figured I'd post this to let everyone else know. Cephalexin works well."
