I am new to health Unlocked and I am enjoying reading many posts on many topics written by very friendly caring people. I am 80 years old and Live in British Columbia, Canada. I had my first bout of af about three months ago. Presently I am trying out different prescriptions prescribed by my cardiologist. So far I have tried Rivaroxaban then switched to warfarin when I discovered that there is no antidote for the former. I am fine with calcium channel blocker's and beta blockers which I have been on for many years. However, My doc wants me to to switch from the old beta blocker to the new namely, sotalol. I start today and I am not looking forward to it as it too has some serious side effects. I was also on amarodion for about a month but took myself off when I learned that permanent blindness and destruction of vital organs are possible side effects. That was just too much. I am sure the doc is frustrated. In fact, I know he is.
