FloMax is a very common drug prescribed for prostate problems. If I remember correctly if the patient does get off it, it's gradually under the guidance and advice from his doctor. Some meds shouldn't be stopped suddenly and I think FloMax is one of them if I remember correctly. Your urologist should be able to tell you if and when you need to stop.
I personally take Cardura instead but it's usually recommended if the patient also has high blood pressure. It will lower it so if high blood pressure is not and issue it probably shouldn't be taken.
Finally both my internist and urologist suggest I take the supplement Saw Palmetto daily. You can find a good quality one at your local Health Food Store or Vitamin Shop.
Hoped this helps some.
