It is not uncommon for patients who are taking anticoagulants such as Coumadin (wafarin) to be taken off of it before an invasive procedure to reduce the risk of bleeding. Depending on your individual risk factors, you may need to be “bridged”, meaning switched on a different anticoagulant that wears off quicker than Coumadin. Usually that is Lovenox (enoxaparin), which is similar to Heparin and is administered as a shot once or twice a day.
