Thank you for your response. Yes, my doctor does know about the extra beta blockers. I'm happy you've been spared nausea symptoms. That's always good! :)
If anyone else knows of a safer medication, I would be grateful.
I hope you are taking Zofan with the knowledge of your beta blocker prescribing doctor. Taking an "extra beta blocker" seems to be questionable to me, unless so prescribed by an MD.
Sorry I can't help on a "safe" alternative, nausea is one symptom I've been spared, and I"m thankful for that.
