Michaelena:
Al Lodwick will tell you that the latest studies show no difference between Coumadin & the generics.
My PCP oversees my anticoagulation, since my cardio is in Dallas. The first year post-op, Coumadin wasn't so expensive. Then my insurance plan changed the cost of name brand Rxes in 2004. I asked to switch to generic. He said OK, since I have my own testing machine and could detect any significant changes in INR after the switch. There wasn't any. He's OK with generic warfarin, although others in his office think the opposite.
I get Taro warfarin through Medco. My INR is usually 3.2-3.6.
I'd rather have the extra bucks in my bank account than lining the coffers of a big pharmaceutical company. There's always another medically-related bill I have to pay.
