Anyone taking an ace inhibitor? If so , which one? My dr. just gave me zestril to add to my ziac because theoy are worried about my rapid heart beat and heart and kidneys. Zestril has allergic side effects and I am worried about taking it because i have severl relatives with allergies assoicated with zestril. If you can tell me some other ace inhibitiors that you are taking and sosage I would appreciate it. Thanks, Too tired to research at the moment.
