This clinic that I go to so that I can get monthly blood draws (to compare to my meters) doesn't prescribe more than 30 days at a time. This clinic is at a hospital that was destroyed by an earthquake in 1971. They don't trust their patients, for some strange reason, with more than 30 days worth of warfarin. (I have a supply that I got months ago, and it should help carry me through if I ever have an emergency and am unable to get warfarin).
I often wonder about the logic, or sense, of this anticoagulation clinic. (They refer to me as 'Mr. Consistent.' Could it be related to the fact that I do my own monitoring and management and usually check my INR before a blood draw or a visit to the clinic?).
