I've only been on apixaban for 10 days but am finding now every morning I wake up with a heavy, fuzzy head headache that is difficult to shift. I don't want to rely on codeine based painkillers because they make me a bit nauseous at work. Does anyone else hear have this on starting apixaban? Quite stressed about everything currently - the consultant and my own doctor are not singing from the same hymnsheet, as regards my AF (or is it AF?) Ugh.
