I have been on bisoprolol 5mg daily since Sept last year after two events of tachycardia in close succession. Prior to this, the last events were one in 2011 and one in 2012 which raised no concern for the doctors and no treatment. I have had (or so i thought) minimal side effects from this drug. However, i noticed recently that i have put on around 9 pounds which is a massive deal for me. Reading other posts.. it looks like bisoprolol could be the culprit...my diet hasnt changed and i exercise regularly...3 times a week cardio minimum. The thought that the drug could be to blame is really worrying me as i dont feel in control. Im thinking of speaking to the GP about being weaned off the drug. The cardiologist said I had three options back in December...do nothing, take the tablets or have ablation. Im on the waiting list for ablation but have already decided I don't want to go ahead...for something that bothers me very infrequently ( and the doctor says is not high risk in a patient like me) ablation seems far too much of an ordeal and risky. I'm 35.
