Colonoscopy - Fleet Phospho-Soda Two Day Preparation

Have someone drive you or be available to drive you home the day of the procedure. Due to the sedation you will not be allowed to drive yourself. Somebody responsible for you can accompany you in a taxi, but no public transport is allowed. This is for your own safety. Your procedure will be canceled if you do not have a ride.

It is recommended that you do not go back to work, do any strenuous exercise, drive or sign any legal documents after the procedure.

Please contact our office immediately if you have any of the following medical conditions and have not already discussed this with us:

Please notify us if you have special health care needs.
