I took inderal for years when younger, I got really sick from inderal, I was changed to lanoxin this worked great, then I was taken off and put on diovan. My problem is PVCs, really bad after I had a heart attack when I was 37' I am now 75 and the PVCs are awful and now a fib, I was put on carvedilol about 2 years ago and I did not get better now I feel awful. I need control of my heart bear not some med that makes me sick. I also have hostimotto disease. I am really sick and no one seems to know the answer. I also take synthroid.
