Sister, I'm certainly not an expert, but I 've been taking 10 mg. Altace (ramipril) for 4 months now and have had excellent results with it. When I started the Altace in March, my BP was 204/110. Now it runs in the 120's/70's and sometimes even lower. Saturday it was 107/73. I have noticed no side effects at all, and the great part is that I can get out in the summer heat without feeling weak or faint as I did last year when I was on labetalol and lotensin ( another ace inhibitor). Also, I didn't have that irritating cough you usually get with ace inhibitors. We have some real experts on this board so you'll probably be hearing from some of them. Good luck.
