Thanks. I'd thought that it might be weight based, makes sense.Don't feel bad. My dosing has been all-over the place. I started on 7.5mg in the hospital. Then sent home and was told to take 6mg daily. Holy crud... that let to INR of 4.4. Some weeks my INR is 3.2, or a 2.5. It's all a guessing game till they figure it out.
My doctor has said that Warfarin is weight based... which a lot of it he is right.
Right now I am alternating 2mg 3 days a week and 4mg 4 days a week. I have a feeling it will still be on the high side when I get checked tomorrow.
