Could take 90 days to work; shrank enough to speed flow. Side benefit is that it is also now known to reduce risk of bladder cancer.
It is expensive on my insurance policy; name brand with no generic (yet) so I pay maximum co-pay.
Drawback is that it kills your nightime activity, but we're in our upper 70's so we expected that.
As far as I know, it is the only drug in the market that does a reasonable job on the prostrate. I see lots of "snake oil" remedies in ads; my urologist says none of them work.
Your results may vary.
