If you're taking anticoagulants and you need to have surgery or any kind of invasive procedure, make sure that the healthcare professionals treating you are aware of your medication. This includes procedures used to diagnose other conditions, such asan Endoscopy or cystoscopy .

If you're having a dental procedure, such as having a tooth removed, tell your dentist that you take anticoagulants. You may not need to stop taking your medication, but you might need to have a blood test before the procedure to make sure your blood clots at the right speed.
Only stop taking your medication on the advice of your GP or another healthcare professional.
