I ve been on antihypertensives for 40 years. I am 64. I have never been overweight, my siblings and I have all had early diagnosis. I do not smoke, I eat well, and I exercise, but my diastolic pressure has always been stubborn. Question: I ve developed a drug induced cough before, and have again developed another dry cough (for 3 months) which I suspect is from the Diovan/HCT that I have been taking for the last 4 years. I have been on all 3 of the classified BP drugs over the years and am wondering if I should return to the calcium channel blocking agents as they seem to have the lowest incidence of developing a cough. I am an RN. Thank you. S.
