I have a very bad upset stomach this morning. I phoned the Warfarin Clinic to check if I should "up" my Warfarin as the leaflet given to me said that an upset stomach makes the Warfarin less effective. The answer was - you have IRN check due on the 16th December and your IRN will by then have recovered.
My query is that I feel I am not covered for an AF episode at the moment, my stomach is so empty. Any reassurance that I still have some Warfarin in me would be appreciated.
