I'm a 58 year old female & I take good care of myself & I am very healthy. I've had borderline HP off & on. I tried a Beta Blocker 5 years ago & took myself off it, since some of my symptoms were due to my Hypothyroid. I started Lisinopril today 10 mg, I felt a central nervous system affect almost immediately. Tonight, I'm feeling very tired which I think is due to the Lisinopril. My BP today was 152/98 it was 140/98 the week before @ the doctor's office. Tonight @ home it was 115/70 & 100/68 I have been monitoring myself @ home & some of my readings are a little high but a lot of them seem normal. I'm getting a better monitor tomorrow. I know, there is such a thing as white coat syndrome. I could lose 15-20 lbs. which might help too. I'm very active but that doesn't seem to help. thanks for all your postings, it has really helped me... My doctor did mention getting a cough as a side affect.
