I am wondering if you are uneasy about taking
digoxin. If so, I would ask you cardio if you can get by with just the TOPROL XL.
Digoxin, xanax, toprol xl, and lisinoprol seems like a lot of stuff to be taking.
I am a runner and only take TOPROL XL 12.5mg. This knocks out my extra beats and really slows my heart down. A little seems to go a long way for me.
