Side effects
Contraindications
What are the contraindications for warfarin?
Pregnancy
Significant risk of major bleeding
Active bleeding
How can you explain how warfarin works to a patient?
Thins the blood to treat or prevent blood clots
It does this by blocking vitamin K which is the vitamin used by the body to make clots
