hello Chris,
I am Dr.Rajesh Teli,MD.
I have gone through your query.Thanks for using HCM.
Basically the effect of warfarin is very variable in individual and is affected by many external factors.It is affected by intake of green leafy vegetables,extremes of climate and concomitent medications.
That is the very reason you have to monitor PT iNR and adjust the dose frequently to maintain INR around 2.5.
As long as it remains between 2 to 2.5 it is reasonable.otherwise you should increase or decrease 1mg on alternate days .If INR less than 2 you increase 1mg on alternate days and if above 2.5 decrease 1 mg on alternate days.Monitor it every 15 days and then every month and then every two monthly once it is stabilised,
My best wishes
Dr.Teli.
