Prior to the esophageal dilation, you will need to fast (not have food or water) for a minimum of 6 hours. You should follow your doctor’s pre-procedure instructions regarding fasting time.
During the procedure, your doctor may use sedation in order to help you relax and not remember the procedure. If this method is used, you will need someone to drive you home, as common medications used in this procedure include: fentanyl, versed, or propofol. All these medications require that you do not drive for 24 hours.
Alternatively, your doctor may use a spray anesthetic to numb your throat to perform your procedure. If this method is used, you will be fully awake for the procedure and would be able to drive. After the procedure, you will be given instructions on when you can eat and drink. Drinking will be withheld until any anesthetic effects have worn off. This is so that you do not have liquid go into your lungs instead of your stomach, since the anesthetic inhibits the normal swallowing functions. You will likely also have a mild sore throat for several days after the procedure.
