I have used uroxatral in the past (about 5 years ago); and it seemed to work only half a day, so I discontinued it, and put up with the BPH symptoms. I believe that may have been due to my iliostomy, and the fact that food is excreted within a 6 hour cycle; therefore I don t get the full benefit of a timed-release medication. Is it possible to get a prescription that can be taken twice a day, assuming my analysis is factual? Thanks, R.Williams
