Hi Ray....I agree w/ed34. Warfarin is generic for Coumadin. Since it is the generic for brand Coumadin it is given in same dose. Mom took Warfarin for the 1st three months after her event. Month four, the pharmacy was temporarily out so I took brand name Coumadin (more$$, of course ;-) but it was the exact same dose. Month five, she was back on Warfarin.
Best to you... GV
As far as I'm aware, Coumadin is just one of the brand names of warfarin. It's like if I want some Clopidogrel (another form of anti platelet med) I could ask for either Clopidogrel or Plavix, Plavix is the brand name the drug company trades the medication under.
