Flomax for Kidney Stones: Can it be Used by Women?

Health Professional

Dear Dr. Motola,

Can Flomax be prescribed to a female to help pass kidney stones? I am a female patient who has been passing kidney stones for several years. Today I was prescribed Flomax to help me pass kidney stones. I have had two episodes of urinating blood due to kidney stones. No pain; only blood, large amounts for over two weeks each time, seven months apart. I am concerned since Flomax is only prescribed to males; what kind of side effects coudl it should have on me?

Both alpha blockers and calcium channel blockers have been utilized to help facilitate the passage of ureteral stones in both men and women. Conflicting data however exists as studies that were recently presented at the meeting of the American Urological Assocation suggest that in several randomized clinical trials there has been a lack of benefit to using alpha blocker to help stone passage, although less pain, urinary urgency and frequency were noted when these agents were used.
