I have been taking lisinopril for 5 years, recently taken off and put on cozaar. I have had extreme anxiety , and my cough was just as bad. Now i am being changed to norvasc , which seems like it will be the same as cozaar. I had a by pass 4 years ago. Nothing seems to keep my blood pressure regulated, but i am wanting to get off this medicine merry go round. Do you think it would be best to go back on lisinopril, since the cough is nothing compared to extreme anxiety, and dizziness .
