Blood pressure medication becoming less effective??

Thank you for your response Northernsoulnana.

I find all of this quite scary as I have never had any health issues before. It is a terrible cycle of worrying about your high blood pressure which makes you stressed and increases your blood pressure.

When I first went on the BP medication I had all of the other checks (heart etc.) and everything was fine. I started going for a walk every morning and lost a bit of weight. I am 14st3lb and 5'3" so I am overweight. I cut down on the drinking.

In May last year I seemed to be doing fine on the medication and my blood pressure was acceptable to my doctor. My initial enthusiasm for walking fizzled out and some of the drinking crept in again. I assume I put a bit of weight back on. However, I didn't expect my BP to go so high

I am scheduled to have the colonoscopy on 10 March now so I need to get my bp sorted by then.

I have terrible white coat syndrome. The nurse taking my bp at the hospital didn't help. She told me my bp was really high and that I was at risk or a stroke or heart attach. Just the thing to calm me down !!!

I am monitoring my bp at home now I am on the higher dose. It is fluctuating quite a bit at the moment. Ok in the morning but higher at night.

I have to see the nurse in a couple of weeks. Hopefully I will have my medication sorted by then. If it is still high, I think I will ask my doctor if he can give me something on the day of the colonoscopy to ensure my bp is acceptable.

Wishing you well Northernsoulnana. I guess we have both been lucky so far.

I was put on 10mg of the same drug as you Pink Cosmos before christmas i had attend an appt at outpatients early November (rhumetology) and my BP was high.
Was advised to see my GP. i saw GP and I had to do a Blood Pressure Monitering form for two weeks.
Everytime over the past two years i have done these BP Monitering Forms and im always told im Borderline, to go on meds.
My GP rang and told me im Borderline again after filling in the latest form and as ive now just turned 70 he advised me to go on them.
He wanted me to do Readings again for 5 days and submit them to him after two weeks.
He will decide if im to stay on them .
I dont really know whats going on now
As i appear to have AF by the monitor,which i have never had before and my readings are high and higher than they have ever been and im on Blood Pressure meds.
I was put on Statins at same time.
And i just dont feel as well as i did before all these medications started.
I have now got to the age of 70 and now on pills, guess ive been lucky so far.
Im now waiting for my GP to call after reading my Blood Pressure Form
I will also tell him about these Statins.
I also suffer white coat syndrom
I had yo have a Cystopathy 18 months ago
My Blood Pressure was taken twice seperately and very high.
I was told i need to try and calm down, nurse sat and chatted to me
The clinician doing the procedure gave me a chance to calm down, i eventually went in a lot later than i was supposed too.

I have only been taking bp medication for just about a year.

I do realise that it does get higher as you get older.

My issue was my bp readings were fine for 5 months on the medication so I stopped checking it at home. I was doing it every day and getting a bit obsessive about it

In the intervening 8 months since May it has risen to 160/100 despite me taking the exact same medication - which was working fine for the first five months.

I don't understand why it has done this. Nothing else has changed other than I have cut down my wine intake since January. I only have a drink on Saturday now. Previously, I was sharing a bottle of wine most nights with my DH

Blood pressure rises steadily as we get older. DH takes about 4 or 5 different drugs for his blood pressure. He sees thedoctor regularly and all his medication is always being tweeked.

I started taking 10mg of lercanidipine in January last year as I was diagnosed with high blood pressure.

My high BP was discovered at a hospital appointment where I was going for a procedure (colonoscopy) . They would not do it because my bp was too high.

This was a bit of shock to me as I have had good health all of my life. I am 68 and have never taken any long term medication.

I started taking 10mg of lercanidipine in January 2025. It was working well. The GP was happy with it and I was doing my own BP monitoring at home.

I was getting a bit obsessive about it so I decided to stop checking my BP in May 2025. I just assumed it would carry on being OK.

I was scheduled for the colonoscopy again last week. My BP was too high again 210/115, so, once again, they would not do it.

I had a colonography last July which showed I have polyps. I have been waiting since then for this colonoscopy appointment.

I get terrible white coat syndrome. I did check my BP the week before the appointment and it was averaging 166/100. I knew this was high but stupidly did nothing about it. I was assuming that the machine was faulty. In hindsight I should have gone back to my GP. Hindsight is a wonderful thing.

I am now on 20mg of lercanidipine (double my previous dose). My BP is coming down to a good level now

I just wanted to ask if anyone had any experience of BP medications not being as effective as they were initially.

Is this going to keep happening?

Am I destined to spend the rest of my life checking and worrying about my blood pressure?
