Kevin:
If you have insurance the medication should be covered. Coumadin, which is the brand name costs $57.80 for 90, and Warfarin, which is the generic costs $31.84, at our pharmacy. (both are for 5mg). This will give you an idea. Prices vary according to the strength of the medication, number purchased, location purchased, etc. People who do not have insurance must pay the cost themselves because Coumadin/Warfarin is not an option for those who have valve surgery. Your doctor will decide whether you will take Coumadin or Warfarin. Some doctors have a strong preference for one or the other. Hope this helps.
