The cost of warfarin without insurance can vary significantly, ranging from approximately $10 to over $100 for a 30-day supply, depending on the dosage and pharmacy.
How much does warfarin typically cost at pharmacies?
A 30-day supply of warfarin 5 mg tablets can be found for as low as $10 at some pharmacies, while other locations may charge upwards of $100 for the same quantity and dosage. Prices are influenced by the specific pharmacy, the brand of warfarin, and the dosage prescribed [1].
Can I get warfarin at a lower price with a discount card?
Patient assistance programs and discount cards can substantially reduce the out-of-pocket cost of warfarin. Some programs offer significant savings, potentially lowering the price to around $10 to $20 for a month's supply [1].
What are the common dosages of warfarin?
Warfarin is available in various tablet strengths, including 1 mg, 2 mg, 2.5 mg, 3 mg, 4 mg, 5 mg, 6 mg, 7.5 mg, and 10 mg. The prescribed dosage is individualized based on a patient's specific medical needs and is adjusted based on regular blood monitoring [2].
How does warfarin work?
Warfarin is an anticoagulant, commonly known as a blood thinner. It works by inhibiting vitamin K, which is essential for the synthesis of certain clotting factors in the liver. By reducing the activity of these factors, warfarin decreases the blood's ability to form clots [3].
When does warfarin's patent expire?
Warfarin has been available for many years and is now a generic medication, meaning its original patents have long since expired. This is why it is widely available and relatively inexpensive [4].
Are there alternatives to warfarin?
Yes, several newer anticoagulant medications, known as direct oral anticoagulants (DOACs), are available. These include drugs like apixaban (Eliquis), rivaroxaban (Xarelto), dabigatran (Pradaxa), and edoxaban (Savaysa). DOACs often have fewer food and drug interactions and do not typically require routine blood monitoring like warfarin [5].
How do DOACs compare to warfarin in cost?
Without insurance, DOACs are generally more expensive than generic warfarin. The cost of DOACs can range from $200 to over $400 for a 30-day supply, although prices can vary by pharmacy and specific drug [6].
