DOSE 1 – On the Day Prior to Colonoscopy

STEP 1 At 5:00 PM Open 1 flavor enhancing packet and pour the contents into 1 bottle.

STEP 2  Fill the provided bottle with lukewarm water up to the fill line. After capping the bottle, gently shake the bottle until all powder has mixed well (dissolved). For best taste, refrigerate the solution for an hour before drinking. Do not freeze.
