Polyethylene glycol (PEG) Colonoscopy Bowel Preparations

There are two types of polyethylene glycol (PEG) preparation that may be used for bowel cleansing. A prescription is needed for any PEG preparation. Your preparation should begin the day before your colonoscopy and finish the day of the procedure. Prepare and chill the PEG oral solution the morning before the procedure (it tastes better cold). Plan to be near a bathroom for the entire evening. Feelings of nausea and bloating are common; they will go away with time. The bowel cleansing will be improved if you drink at least one (1) gallon of clear liquid during the evening. See the colonoscopy booklet for allowed clear liquids.

An A&D type ointment applied to the rectal area can help with any irritation. The goal is for your stool to be clear or light yellow water.

On the day before the procedure, eat breakfast in the morning. Do not eat any solid food after breakfast. Oral bowel preparations work best on an empty stomach.

For all colonoscopy bowel preparations, stop drinking all liquids two (2) hours before your scheduled appointment time.

PEG preparation (NuLYTELY, CoLyte, GoLYTELY, TriLyte)
___ Between 4 pm and 6 pm the day before your colonoscopy, begin drinking half (about 2 quarts) of the PEG solution, which you have mixed ahead of time and chilled. Drink a glassful (8 ounces) every 15 minutes until the entire two (2) quarts are gone. Your bowels may begin to move in about 30 to 60 minutes.
___ The day of the procedure, drink the remaining two (2) quarts (half of the solution) starting at least 4 hours before your scheduled appointment in the procedure unit. Be sure to add driving time to the 4 hours.

MoviPrep preparation
___ 6 pm the day before your colonoscopy, begin drinking half (1 quart) of the MoviPrep solution, which you have mixed ahead of time and chilled.

___ 7 pm to 9 pm the day before the procedure, drink two 8-ounce glasses of any clear liquid of your choice (see the colonoscopy booklet for allowed clear liquids).
___ The day of the procedure, drink the second chilled quart of MoviPrep solution, an 8-ounce glassful every 15 minutes, starting at least 4 hours before your scheduled appointment in the procedure unit.
