Yes, I've taken Ziac before, and had no side effects other than dry mouth. Had no sexual dysfunction at all. I also had a friend who was on it, and it caused her to become dehydrated, but her dr. just told her to drink more water and fluids. I'm on Toprol now, but I don't like it as much as I did the Ziac, and am thinking about having my dr. switch me back to Ziac. I'm on a beta blocker for BAD symptoms with Mitral Valve Prolapse.
Anyway, that's all I noticed when I was on it. Also, I remember losing weight on it.
