I’ve just discovered that something totally unsuspected has been screwing me up badly for over 18 months. The culprit? Furosemide (Lasix), my diuretic.
For the last couple of weeks it’s been largely forgotten, not entirely sure why, except possibly a subconscious aversion to the pain of having to walk six yards each way for a pee every half hour.
During that time my heart has been ticking along nicely. Occasionally tachy (related to my Salbutamol intake, I’m pretty sure), but steady and strong. It’s also stopped misfiring, flatlining, and throwing PVCs, mostly. None of that is subjective, I can see it clearly on my pulse ox. Blood pressure is low normal, too.
Anyway, about 90 minutes ago, I took a dose, and an hour later I felt absolutely appalling.
Right now I feel dreadfully weak and shaky, slightly panicky, with very blurred vision, yet, apart from what I think of as my baseline crapola, I felt OK before taking the Furosemide.
A look at the PIL suggests that not only is it responsible for how ill I feel right now, it’s also at least partly responsible for problems that I’d ascribed to my heart meds. Not entirely wrongly, as I do feel much better without them, and my heart and BP are much better behaved, but I now feel that Furosemide might have been amplifying the problems.
One biggie is that for months I thought I was losing my sight. I am, as I’ve mentioned previously, but for months I’ve been peering at my computer screen as if through a frosty window, so I naturally assumed I was getting worse. Why didn’t I see my doctor? Well, I’m pretty much maxed out on bad news, I can’t deal with any more.
I’m not getting worse, though, it was the bloody Furosemide.
It’s also quite possible that Furosemide was responsible, in part or in whole, for the huge problems I had with the beta-blocker Nebivolol. And no, I’m not trying it again without Furosemide! I’ve had enough and I’m doing very well without it.
So, since Furosemide, for some months now, has been increasingly ineffective, so much so that I’ve had to max out the dose (120mg once a day), I see no point in continuing with it.
I’ll do some research over the weekend, to see if I can find a diuretic with fewer problems than Furosemide (the chance of finding one with no adverse effects is zero), and ask my GP to change my prescription on Monday.
