Gallon Prep Instructions
This bowel preparation requires a little organization but is an extremely important part of your colonoscopy to ensure you have the highest quality exam. Bowel preparation starts days prior to your procedure, as you need to stop taking certain medications or supplements and change your diet. If you do not follow these directions, your colonoscopy may be cancelled.

- You cannot go home alone (no walking, bus, taxi, Uber, etc.). If you don’t have someone to take you, your procedure will be canceled.
