Tested myself last Wednesday (there was a reason but no idea what it was!) and it was 4.7 (range 3.0 -4.0). Normally I would ring the nurse but she doesn't mind me adjusting small amounts providing I don't do it too often. So I dropped 1mg and retested today and to my horror it was only 2.3. Ever helpful hubby suggested perhaps I had forgotten to take a dose but I'm sure I didn't so no idea why this blip. Haven't been this low for a while. Since I developed fibro fog two yrs ago I have sometimes wondered how effective warfarin is but as I am in a total daze today and feel like death I realise just what a difference it does make.
The nurse is going to find me some tinzaparin and leave it out for me to collect after 3.00 so I am covered until my inr goes up. So hopefully I should feel better by tomorrow.
