After being diagnosed with AF December 2015 and taking until 8 February for my INR to reach 2.5 my clinic extended my visits to once every two weeks. My average warfarin dose is 3.6mg. As I was leaving the country for six weeks (and do so at least three times a year) we bought a Coaguchek XS for self testing. So far so good.
On the journey to Spain I developed a nasty fluey bug - lots of coughing and aching joints, which lasted about eight days. A couple of days ago I tested my INR - 4.6! I emailed my results to the surgery followed by a phone call - they had not received the email and I wasn't able to resend during surgery hours. What to do? My husband did a fair bit of research on the internet and as I am well outside the therapeutic range the advice (from medical sites) was skip a dose, which I did last night.
I had no absolutely no idea until now that illness could affect INR readings. And I now see that even this skipped dose may well take five days to show on my INR reading. Unless some of you lovely helpful people on this forum know better?
