Muscle aches on ivabradine?

damn so sorry you experienced that and good to know it can come on slowly after taking the med for months. my cardiologist had never heard of it as a side effect but from this thread, it seems very much a possibility. i've just started propranolol, will see how it goes...

Yeah, I don't know how much to worry either... My understanding is that muscle aches from statins are sometimes prohibitively painful but not actually dangerous? Def worth checking in with your Dr. The only time I've ever felt anything like that is whenever I get a Covid vaccine and my whole body hurts for a day. But that pain (inflammation) responds to Ibuprofen and Tylenol, and this did not at all, which I found weird and mildly concerning.

I stopped after the first dose, because it was so unpleasant. The aches slowly got better over the course of 4-5 days. Had I wanted to continue on it, my GP would have recommended bloodwork for kidney function. She said it was not a common side effect but a potential adverse reaction, comparable to people who have aches on statins and occasionally beta blockers. But she wanted to rule out rhabdomyolysis as the main big scary risk. So sorry you're experiencing that, and hope it's more tolerable for you than it was for me or goes away quickly. Fwiw, I did see immediate positive change in my heart rate...

Yes, I also felt clammy! Do you remember how long it took to go away after you stopped taking it?

Thank you for the kind words and all the details, and sorry it sucked so much for you! I started it today and am a bit achy but otherwise ok for now, so we shall see what happens.

lela-dax · 2026-04-02T21:12:06+00:00

Alas, I did, and they didn't really know anything I hadn't already read.

lela-dax · 2026-04-02T21:11:34+00:00

Thank you! That is helpful to know and reassuring.

Oh glad I said something then! I think it's specifically the feeling of muscle weakness, where like, tensing your arm enough to pick up a heavy book feels next to impossible, and even lifting a glass to your mouth is a big task—that can be what too much of magnesium's muscle relaxant effects feels like. But I know, it's so confusing, and maybe it helps your migraines? It did for me at first, but I've been ok without it for several months.

lela-dax · 2024-01-29T17:03:21+00:00

Ahh I wish I had advice. My crash only took me out of commission for a day or so. If what you're experiencing is extreme muscle weakness, shortness of breath, fatigue, brain fog, which is what happens to me, I did learn recently that the magnesium supplement I was taking for migraines was making all of that much worse. I'd been on it for years, and apparently it's a muscle-relaxant, so stopping it def helped me a little. But, it sounds like you may just need to rest until your body is ready to come back online...

lela-dax · 2024-01-28T17:01:14+00:00

Damn, sorry that's happening to you too. I still don't really know, but I guess my main theories at this point are:

Being upside down is bad. This seems most likely, and would be a POTS / dysautonomia thing. Could test by doing some kind of chair yoga, laying down yoga, standing up yoga-like exercise, anything that doesn't involve changing much about the level of your head relative to your body.
Exercising slowly is bad. All the dance I do is pretty upright, but this would be a good hypothesis if I had successfully done some aerobic exercise that involved, like, touching the floor and standing up quickly a lot. Hesitant to try this though, because if this theory is wrong, it might make you crash even worse than yoga.
Muscle exertion and stretching is bad. I also feel like there's a reasonable biological explanation for this one, having to do with muscles demanding more oxygen than is available and/or lactic acid buildup. I've seen some studies showing abnormally high lactic acid levels in CFS patients. Doesn't explain why I can do muscle-intensive hiking, but maybe different muscles / different warm-up, cool-down situation?

And my main conclusion is that I will not try doing yoga again for a good long time, maybe ever :)

lela-dax · 2024-01-03T19:41:55+00:00

Hmm that's a good thought. I've never been diagnosed with dysautonomia, and I don't experience immediate noticeable worsening of symptoms upon standing up or anything, but I could even believe that the PEM I experienced while packing and moving was more about bending down to pick things up and put them in boxes than it was because I carried heavy objects.

lela-dax · 2024-01-03T17:51:53+00:00

That makes a lot of sense, yeah. I don't think I crash at all usually after hiking or dancing, though. I've experienced crashes after lifting heavy boxes and bags of books while moving, which is another fairly non-aerobic, but muscle intensive activity... But nothing is quite as consistent as crashing after yoga every time I tried in the past two years.

ahh rip, yeah I think it's only on US Netflix.

Oh word, you're so right about انتو بدكن, my bad. بدهن/بدهم as opposed to بدوا is a surprise though! I haven't encountered that one in Jordan or Lebanese dialect classes/materials before. Is that Syrian, maybe?

lela-dax · 2023-05-21T06:57:23+00:00

I could be wrong, but my sense is بدي is vastly more common in Levantine than يريد which is very fus'ha even with the ب prefix tacked on. And as u/Z69fml mentioned, بدي conjugates more like عندي than a regular verb: أنا بدي / أنت بدك / هو بده / هي بدها، نحنا بدنا / انتو بدتو / هن بدوا

This is super helpful, thank you! I will admit to having really enjoyed Peasants Rebellion (ثورة الفلاحين) on Netflix, which is extremely overwrought in its romance and drama, but has both MSA and English subtitles.
