Pre-endoscopy Instructions

These instructions are meant to be a general guideline. You will be given more specific instructions from your gastroenterologist and anesthesiologist. Your anesthesiologist will attempt to phone you the night before your procedure. If your anesthesiologist has been unable to reach you by 9 pm the night before your procedure and you have questions, you can speak to the on-call anesthesiologist through the answering service at 972-566-5632. 

Week before your procedure

You may be asked by your gastroenterologist to stop blood-thinning medications such as Coumadin (warfarin), Pradaxa (dabigatran), Xarelto (rivaroxaban), Eliquis (apixaban), Lovenox (enoxaparin), Plavix (clopidogrel), Effient (prasugrel), and Brilinta (ticagrelor).​​​​​​

It is extremely important that the doctor that prescribed the blood-thinning medication (i.e., cardiologist, primary care physician, hematologist) is part of the decision-making with regards to the timing of the interruption of your blood thinning medication. Some conditions require an alternate, shorter-lasting medication to bridge your therapy before your procedure. Some medicines require up to seven days for the blood thinning effects to adequately diminish. Allow enough time to contact your doctor and learn the safest plan for the interruption of your blood thinning medication.
