Purchase the GoLytely/NuLytely prescription medication (polyethylene glycol) at your local pharmacy or drugstore. Please contact your pharmacist to determine if your insurer covers the cost of this medication. Important –

Do not eat popcorn, seeds, nuts, multigrain bread, salad, cheese, or high-fiber foods for the three days prior to the procedure.

One Day prior to procedure

Do not eat solid foods. It is essential to drink at least 8 ounces of clear liquids every hour after awakening to avoid dehydration.

Clear liquids include:

  • Apple or white grape juice
  • Broth
  • Coffee or tea (without milk or creamer)
  • Clear carbonated beverages such as ginger ale or lemon-lime soda
  • Gatorade or other sports drinks (not red)
  • Kool-Aid or other flavored drinks (not red)

  • Popsicles (not red)
  • Water

Note: Avoid red-colored drinks, Jell-o, or popsicles. Do not drink alcohol on the day before or the day of the procedure.

Instructions for preparing the solution are provided on the medication bottle. The GoLytely/NuLytely solution should be mixed no sooner than 48 hours prior to its usage by adding tap water to the gallon level mark and shaking or stirring the solution until it is well mixed. Do not add sugar or flavorings containing sugar to the solution. Do not exceed the recommended dosage, as serious side effects may occur.

Bloating (a feeling of fullness in your stomach), nausea, and occasional vomiting may occur. Do not be alarmed. If you feel nauseated or vomit while taking the bowel preparation, wait 30 minutes before drinking more fluid and start with small sips of solution. Some activity (such as walking) or a few soda crackers may help decrease the nausea you are feeling. If the nausea persists, please contact your health care provider. Note: Individual responses to the bowel preparation medication may vary. The solution should cause multiple bowel movements, but may take several hours to work

Night Before/Day of the procedure

At 8:00 a.m. the night day before, wake up and mix the provided solution with water up to the top line of the container.  It is important to make sure it is well dissolved.  Let the solution sit in the fridge until 6:00 p.m.

At 6:00 p.m. the evening before the procedure, begin drinking one 8 ounce glass every 15 minutes until half the bottle is completed.  Then wake up 6 hours prior to arrival time to drink the rest of the prep in the same manner; one 8 ounce glass every 15 minutes until the bottle is empty.
