Overactive Bladde
"I am a woman taking flomax for severe urinary retention.  Flomax works wonderfully, although it did not start to work for me until I had taken it for about 3 weeks.  Initially there was some mild drowsiness and dizziness, which has mostly subsided.  Make sure you talk to your doctor about getting on a bathroom schedule so you can eventually stop taking this.  I was going 15 to 20 x/day and not able to empty below 200 ccs.  This combination has gotten me down to going only 6 or 7 x/day, and completely empty."
