Prior to having ERCP, there are a number of things you will need to remember:

•    First, don’t eat or drink anything for at least six hours beforehand or after midnight if your ERCP is scheduled for first thing in the morning.
•    Be sure to tell your doctor all the medication you are taking, including aspirin, aspirin-containing drugs, or blood thinners.
•    Identify any allergies or any reactions you have had to drugs, particularly antibiotics or pain medications.
•    Follow all of your doctor’s instructions regarding preparation for the procedure.
ERCP can be done either as an outpatient procedure or may require hospitalization, depending on the individual case. Your doctor will explain the procedure and its benefits and risks, and you will be asked to sign an informed consent form. This form verifies that you agree to have the procedure and understand what’s involved.
