Hi has anyone taken this drug? I was given it and I am sure it made my symptoms worse in less than 2 weeks! I had to be admitted for the 2nd time in a month for three days with a rate of over 203 in AF. The first time I was not on it. I have now been put on Metoprolol and Fleconide which please god seem to be helping. I came off beta blockers over 2 years ago as I got heart block with them after 2 years being on them but needs must I guess I would rather feel the ectopics and missed beats than the full blown AF! I hate this so much got diagnosed Xmas after 10 years of seeing cardiologists with SVT and so called anxiety! I live in fear does it get better?. Am hopefully getting ablation lucky i pay for private medical lets hope it works, this is awful and I never realised so many people suffer from it. Best wishes to you all.
