Warfarin - Coumadin, Jantoven

Warfarin is an anticoagulant (blood thinner). Warfarin reduces the formation of blood clots.

Warfarin is used to treat or prevent blood clots in veins or arteries, which can reduce the risk of stroke, heart attack, or other serious conditions.

You should not take warfarin if you are allergic to it, or if:

  • you have very high blood pressure
  • you recently had or will have surgery on your brain, spine, or eye
  • you undergo a spinal tap or spinal anesthesia (epidural)
  • you cannot take warfarin on time every day
  • you are prone to bleeding

When you’re taking warfarin, in case you miss a dose, you need to take the dose as soon as you remember.

When you’re taking warfarin, there’s a chance you may bleed when shaving or brushing your teeth. It’s recommended to use extra care to prevent the bleeding.

Foods that are high in vitamin K (liver, leafy green vegetables, or vegetable oils) can make warfarin less effective. If these foods are part of your diet, eat a consistent amount on a weekly basis.

Grapefruit juice, cranberry juice, noni juice, and pomegranate juice may interact with warfarin and lead to unwanted side effects. Avoid the use of these juice products while taking this medicine.

Avoid drinking alcohol.
