Like others here, took a good time to get my bp meds correct. I was only in my early 60's when a routine check discovered my bp was very high. I had been due to have a small procedure at the hospital where I worked, and popped over to have the pre-entry checks, when this came up. They would not even let me home that day until I had confirmed an appointment with my GP.
I had no symptoms, felt well and was very active, probably very slightly over-weight, but nothing much. Anyway GP put me on one of the cheap Rampiril tabs and I took these, bp came down.
Coughing fits became so frequent over next few months I got referred to hospital chest clinic. As each day went on, this coughing got worse, by the evening I would lose total control as I was racked with these.
Professor at chest clinic was brilliant, did all the checks and tests, but was correct in his first diagnosis that this cough was due to this bp med. Eventually he wrote to GP saying I was not ever again to have anything in the 'piril' range.
Took a long time to find a combination of drugs that really worked for me. Several years, but eventually Losarton and Bendroflumethiazide tabs taken daily keep my bp well within range and so confident am I with that medication that I have long ago lost my 'white coat' syndrome. And, as far I can make out - no side effects.
I know it is they that keep my bp good. I somehow lost a strip of one one them and ran out just for three days as I was away from home and could not contact doctor, and even in that short time, my bp started to rise.
We are fortunate, that for most of us there is the right combination that works for us. No good GP will get fed up with any patient that perseveres.
