Preparation Procedures for Upper Endoscopy

Seven Days Before the Procedure

Medication Restrictions

  1. Diabetics taking insulin will need dose adjustment the day before the exam. Please ask for advice from the physician that prescribes your insulin. For diabetics only taking diabetic pills simply do not take
    the pills the day of the procedure (see below).
  2. Blood thinners including Coumadin, aspirin, and Plavix type medicines. These can increase the risk of bleeding during endoscopic procedures to a varying degree. We recommend stopping Coumadin three days before the procedure, if possible. Please ask for advice from the physician that prescribes your Coumadin. If aspirin is used for preventative reasons and not for active cardiac or stroke prevention then it should be stopped for 7 days before the procedure. Discuss the use of other blood thinners, such as Plavix, with the prescribing physician.
