I have taken warfarin for 8 years. For 6 of those years I have measured my INR at home. For 2 years I have with the tacit agreement of the GPs Warfarin clinic, adjusted my Warfarin dose myself.
This has meant I can anticipate changes in INR when starting new meds or if I am unwell. I have learned about the things that impact my Warfarin dose and can achieve decent INR control without too much effort.
Much as I would if I was taking Insulin. I recommend it to you.
It's all about taking back control Aunt Ethel. Just go easy on the alfalfa and those multivits. If you insist on eating a sackful, then do make sure you eat that sackful every day Auntie. The alfalfa that is.
Baaa....humbug, said Auntie.
