Hi Hannah,

Welcome to the board! I am taking Altace to try to prevent kidney problems. In the past, I have had trouble with a higher dose than I'm taking now. One thing that helped me was drinking a lot of water. I drink about 12-14 cups per day. When I used to get that light-headed feeling, I would drink a glass and feel better. Maybe this can help you. Good luck and I hope you start feeling better soon.

I take 5mg Altace and have had no side effects except for a slight cough, which went away in a few weeks.
