THE DAY OF THE PROCEDURE:
In the morning, you should use inhalers, and take heart, blood pressure, seizure, anti-anxiety, and respiratory
medications with a sip of water, enough to swallow them (no blood thinners or oral diabetic medications). You should
wake up early and take these at least 2 hours before your test, even if you are having an EGD with your colonoscopy.
On the morning of the procedure you may pass some cloudy or dark liquid stool. This is common and not something to
be concerned about. If you drank the prep until your stool was clear the day before, your prep is probably fine.
Female patients of childbearing age will be required to provide a urine specimen for a pregnancy test prior to anesthesia
the day of the procedure. Please avoid urinating prior to arrival the day of your procedure to prevent delay or possible
cancellation.
TRANSPORTATION HOME:
Because of the medications you will be given during the procedure, you will need someone to drive you to
the facility and then drive you home. You will not be able to use a taxi or bus. The test may be cancelled if
you do not have a driver. There will be no exceptions. After the procedure, you may resume driving the next
day unless your doctor instructs you differently. If you have any questions, please call our office at 1-855-ILLGASTro/1-855-455-4278.
