Follow your doc recommendations. but, I imagine you don't have to because you are only switching from one beta-blocker to another. So, you are essentially not lifting the beta-blockade.
Beta-blocker therapy should not be withdrawn abruptly (particularly in patients with CAD), but gradually tapered to avoid acute tachycardia, hypertension, and/or ischemia.
My cardiologist did a "wash-out" of Sotolol before initiating another medication. It generally takes 2-5 days to clear this drug from your system.
Your question leads me to wonder if you got your prescription from a medical doctor. It seems that person would tell you how to transition.
I hope you are not getting meds off the "web" and self-testing.
I haven't looked up, but isn't sotalol and atenolol anti-arrhythmia drugs,or are they indeed just another beta blocker - like metoprolol (maybe the ending "lol" is the key to the answer - I'm still learning the extensive drug names).
The "lol" is in fact the beta blockers. I do know sotalol is a beta blocker but nearly in a class by itself. Because of it being sotatolol, I would want specific detailed info from an md and likely a pharmacist too. But.. changing from propranolol to metoprolol and later to carvedilol did not take much of a transition. I didn't have to wean slowly because the beta blockage was still in effect and so not running away with the rhythms... at least no more than was already happening anyhow.
