"After taking tamsulosin for three years, it has proven quite effective with few side effects. Dizziness when standing goes away in two weeks or less with only a residual low-blood pressure when quickly standing from a seated position in the morning. An unlisted known side effect is an occasional skin rash on the feet, ankles, wrists, hands and sometimes lower forearms when in prolonged hot humid conditions."
