I was placed on dronedarone that I knew could give me a non-productive cough. My EP e-mailed to say that the cough would take several weeks to settle. The monitoring GP wasn't convinced about the worsening cough and sent me for a chest x-ray. I've just spent eleven days in hospital with pneumonia and apparently it was only my fitness that kept me from being admitted to Intensive Care. The pneumonia triggered AF and the hospital put me on an amiodarone IV that was subsequently shown to compromise my liver function.
So don't ignore that list of side effects as they may be masking something else. Meanwhile, back to the drawing board for the AF drugs.
