dr leslie,I have been taking Flomax and proscar for 6 months.it seems to be working I am urinating less.my urologist said when I want to stop Flomax just stop.after taking Flomax for 6 months is the prostate used to Flomax,when people stop do they usually have no problem urinating


Proscar acts to shrink the prostate.  After 6-9 months, the prostate may have shrunk enough that the flomax is no longer needed.  If so, then temporarily stopping it will quickly determine if you still need to take it or not.  As the prostate may again grow in the future even with proscar, you may need to go back on the flomax at some future point.

If you were not on the proscar, then stopping the flomax would not be possible without returning to your previous condition.
