Is anyone familiar with the side effects of this diuretic? I have been on 25mg. of this in addition to Accupril because any of the Beta Blockers, including ToprolXL have caused severe reactions. With this latest addition, I have noticed severe pain in upper right abdominal region in addition to problems with urination. I've been on a plethora of blood pressure meds,most either ineffective, or the side effects were so staggering, I had to discontinue them. I am beginning to feel like a guinea pig. Any info on these meds would be appreciated.
