ve been on metoprolol before, and had some awful side effects with that one, but the
bystolic seems to tame those down quite a bit
for me. I've only had two instances in which I could tell I was experiencing some slight side effects (dizziness, slight shortness of breath, pressure).
I've also been told by my GP that, if I find myself with a rapid heart rate or back in A-fib, I can take another 2.5mg dose right then, since it's such a small dosage.
