Yes,I would stay away from the (New) bloodthinners. I would stick to Coumadin/Warfarin. Also you can go to www.Goodrx.com and print or copy a coupon and get your Coumadin/Warfarin for practically nothing.
Simply choose the cheapest pharmacy nearest you. If you cannot print the coupon, simply write down the Bin# and other info.
The last time I used it,costs me $2 for a script!
