Hello tgregg99! I did take Tamsulosin and Finasteride as prescribed by my Urologist in the VA for BPH! I think the length of time was 7-8 years. The problem I have in explaining my perception of its effect on my enlarged prostate! My enlarged prostate eventually grew upwards and into my bladder, to a size that eventually led to urine retention. Tests confirmed the need for prostate surgery…..I chose HOLEP for the solution. I would say that Finasteride didn’t reduce the prostate size as it was eventually removed anyway. But…..perhaps it slowed its growth! This is my opinion only, not a doctor’s! Hope this helps you!
