Treatments and tests

Stopping warfarin

Your doctor will tell you how long you need to take warfarin and when you can stop. Make sure you know which doctor is responsible for managing your warfarin. This could be your specialist or your GP.

After stopping warfarin your blood will return to normal in a few days.

Don’t stop taking warfarin unless told by your doctor. If you stop taking warfarin before it is safe you are at risk of having clots forming in your blood.

If you can’t take warfarin for any reason (such as illness), tell your doctor – you may need to have extra blood tests.

Where to get help


  • Don’t stop taking warfarin unless advised by your doctor.
  • Stopping warfarin before it is safe could cause blood clots.
