My doctor recently put me on a fairly popular blood pressure medication, HCTZ. He selected the lowest dose, 12.5 mg/day. He'd told me that at this dosage it was not diuretic. However, when I started taking it, I definitely felt the effects and my blood tests appeared to show that it had had a diuretic effect (my RBC and other related tests are always borderline/below normal since my kidney was removed, but once I was taking this, they were all in the normal range). I also experienced palpatations.
A search online found this article:
After I talked to my doctor about the palpatations he switched me to a beta blocker instead. I haven't started it yet. I'm a bit more nervous now taking a drug.
I don't really blame my doctor. He's a great family doctor, but most of his patients all have 2 good kidneys, so I'm sure he wasn't aware that he needed to reduce the dosage in patients with mild renal impairment.
I thought this information might be of interest to others here that might be on this medication, since it is a very popular one from what I understand. This is just a reminder to me that I need to do a bit of poking around (looking online, talking to the pharmacist, etc.) just to make sure when I take a new drug where it's metabolized and what effect my lacking two good kidneys will have. (I have to pay special attention, because there's host of drugs you can't take with everolimus, which is another reason for being extra careful.)
Anybody on a beta blocker? What do you think of it? I'm being strongly encouraged by my uncle to get my blood pressure down even if I can't do it through weight loss, he's saying to do it with medication as high BP is hard on the kidneys.
Does anybody know if high blood pressure is particularly hard on the kidneys when you only have one of them?
Thanks and best wishes,
P.S. One of my doctor's patients has recently had a nephrectomy due to kidney cancer and he said the guy is having a hard time. He asked if I would mind if he passed my number to the guy. I'm still evaluating that, whether I like it or not and whether it's a good idea or not. I said sure. My first reaction is to be glad that he's being so thoughtful of this guy and I do think it's helpful to have someone to talk to. The first thing I'll do if he calls is send him here!
