I just started taking Flomax 4 days ago, the 4mg tablets. I have not had any of the side effects that most people on this post have reported. I am 65 years old and have had sky high PSA readings since 1998 and have had 3 biopsies that have all been negative. However, instead of reducing the number of trips to the bathroom the trips have increased but with easier and stronger flow. I take a diuretic for high BP along with other BP meds. I am going to cut down on the diuretic for a few days and see what happens.
