I take aspirin, or anticoagulants or other blood thinners. Do I need to stop these medications before my procedure?

In general, aspirin, anticoagulants and other blood thinners should be stopped at least 3 days prior to your procedure. This is to reduce the chance of bleeding if biopsies are obtained or polyps are removed. There are, however, important medical circumstances in which these medications must NOT be stopped. If you have any questions about stopping these medications, consult your primary physician.
