Hello, I am normally a fit and well 67 year old lady but I was diagnosed with af September after 24 hour episode. In hospital 2 days and given drug through pic line. Cardiologist put me on Apixaban and biosporol. After 3 weeks developed awful headaches, dizziness, flushing, rushing feeling in head. Stuck it out 6 weeks then went GP who stopped biosporal for 2 weeks, still got bad heads. He then changed anticoag to Pradaxa and put me back on biosporal 10 days ago. Cant tell if its going to work, as it only seems to start after a few weeks. Still got the very strange feeling in my head, making me feel under the weather all the time. He ho. Anyone had similar experience?
