When I began taking it, my
HR dropped, as did my already low BP. I have a tendency to faint sometimes, and on the BB my tendency increased 10 fold. So, I dropped back to 1/2 pill and voila...my PVC's are manageable, my HR is more "alert" and my fainting has stopped.
As for the fatigue...that starts to fade after the first two weeks or so. Unfortunately, a beta blocker's job is to lower your heart rate, BP and generally slow metabolism. The result???
