My difficulty breathing has got worse lately so my GP has increased my Bisoprolol to 7.5mg and discontinued my Candesartan. My bp and pulse are relatively normal but I keep getting cold legs and feet followed by a feeling as if I'm trying to breath through fog or at high altitude. I've been getting palpitations after this then all stops for a while and then it starts again.
Anyone any ideas as to what's causing it?
Most likely bisoprolol judging by other memeber's experience. Luckily I never took this devils spawn so can't talk for myself.
I was on bisop for a few months whilst awaiting ablation and it made me very breathless. It is a known side effect. Seems a bit strange that when you complained of breathlessness your GP increased the dose???
Have you seen an EP?
I'm due to see the cardiologist in a few weeks so hopefully they will sort things if it's still problematic. I'm hoping it's just my body adjusting to the higher dose but we'll see.
Thanks
Hi. I have been on bisoprolol since first diagnosed with persistent AF through having a nasty bout of pneumonia and spending 6 nights in hospital last spring. Had to wait 3 months for DCCV in June 2016 which lasted for 2 months, followed by another 7 months 24/7 AF until DCCV 2 March 2017 and back in NSR since then. Still taking all the meds - flec, bisop, candesartan, furosemide and apixaban. I take everything first thing in the morning except for the 5mg bisoprolol which I've learnt is better to take in the evening - then if it makes me fall asleep it is in the late evening and that's fine. My husband thinks it make me snore more though......after 31 years of his snoring, I reckon it time to get my own back!
Take my Bisoprolol at night helps me a bit
