Coumadin vs Warfarin: are they the same?
Coumadin is a commercial brand whose active ingredient is exactly Warfarin. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Coumadin contains Warfarin as its active ingredient. Talking about "Coumadin" in clinical terms is the same as talking about Warfarin at the dose strengths 1mg, 2mg, 2.5mg, 3mg, 4mg, 5mg, 6mg, 7.5mg, 10mg. The differences from the authorised generic are brand, manufacturer (Bristol-Myers Squibb), excipients, tablet appearance and price — not the active molecule itself.

Mechanisms compared

Brand or generic — which to choose?
For most patients, authorised generics of Warfarin are clinically equivalent substitutes for Coumadin and typically cost substantially less. The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
