I felt that my comments to Squady's post should be in a new post as the thread was getting rather long.
The post by Squady and the thread of comments that this inspired just emphasises how careful everyone should be about their Warfarin dosage. To take the advice of anyone other than a doctor is very unwise.
Without going into the details, my sister in law died in January from an internal bleed. She was an alcoholic with AF and other health issues who not only unilaterally changed her Wafarin dose to suit her lifestyle but missed blood tests because she didn't want to attend the surgery for her test appointments over Christmas in the morning as she "was not a morning person". Thus her INR was through the roof when it was checked just prior to her sad death.
As you can all imagine our family was devastated.
For the record I have safely and successfully been on Warfarin for many years. I use the 7 day pill box and make sure that my doses are updated each week. Following my regular blood tests my therapeutic INR level is targeted between 2 & 3 and my doses each week are normally 5 days of 3Mg (one blue) interspersed with two of the days 4Mg (one blue, one brown). The exact days for 4Mg change every time I have a test and yet make little difference to the end result.
I have never had to take such high doses as others have reported in the replies to Squady's post.
I had a very bad accident in January when I severed an artery in my hand and the Warfarin did not help the doctors who spent a considerable time trying to stop the bleeding. But as I am here to tell the tale I am pleased to report they were successful albeit it was a rather traumatic few hours. They used Vitamin K to temporarily reverse the effects of the Warfarin. I had a 3 hour microsurgery operation the following day to repair all my tendons, nerves and of course my artery.
However, having been on Warfarin for many years I do not feel worried about it but know that I should always be aware of the ramifications if things do go wrong.
Remember everyone is different!!!
Regular blood tests
Only take the advice of the professionals
Do not under any circumstances amend or adjust anything on your own
Don't worry but be aware!
