Has anyone taken farxiga?

I am 71 and have persistent atrial tachycardia despite four ablations. Rhythm medications have resulted in bad reactions. I do not want to take amaridorale or tikosyn. My doctor recently suggested I take farxiga to try to improve my ejection fraction which isn45-50. Borderline normal. I am not diabetic nor do I have kidney disease or heart failure. When I read about this drug it is for people with congestive heart failure and or diabetes and kidney disease. My sister had a bad reaction to jardalance which is almost the same drug just a different manufacturer. I have been told once you start this drug it poses complications if you try to come off of it. I feel fine and am on Lisinopril, metoprolol and eliquis. Just curious if anyone else with persistent a-fib or a- tach issues but without these other chronic issues and without heart failure have been told to take this medication. Any insight is appreciated.
