Quick answer

Warfarin is a generic, so it’s usually inexpensive. The price for the same pill can still vary a lot, so compare three places before you fill it.

  1. Check TrumpRx.govThe federal site lists it with partner pharmacy prices: Warfarin.
  2. Check Cost Plus DrugsMark Cuban’s Cost Plus Drugs sells many generics by mail at a published markup.
  3. Ask your pharmacy for two pricesYour insurance copay and the cash price with a free discount card. Sometimes cash is lower than your copay.

Cost tip for warfarin: The pills are cheap, but warfarin needs regular INR blood tests, which have their own costs. When comparing with newer blood thinners, include those visits. Generic rivaroxaban (Xarelto) became available in 2025.
