Instructions for Larger Volume Prep

Depending on your insurance, the preparation selected for you may not be covered and/or may be more expensive than an alternate such as NuLYTELY, GoLYTELY, Peg 3350 or another 4-liter prep. The prescription you were given allows the pharmacy to substitute to the less expensive option. Be aware that the less expensive option is twice the amount of liquid to drink. If you use the 4-liter prep, you will drink half the container the evening before your procedure and the other half on your procedure day.
Please follow these instructions:
Mix the solution with 4 quarts of warm water. Shake well until all the powder is dissolved. Plan to drink the first half of the prep approximately 6-8 hours before you plan to go to bed. Drink an 8-ounce glass every 15 minutes until half the prep is gone. On your procedure day, start drinking the remaining prep 6 hours before your check-in time at NW Endoscopy Center. Follow the rest of the instructions on the prep form you were given. If you start to get nauseous while drinking the prep, slow down. You may find it easier to drink the prep with a straw. You can also flavor the prep with the packets provided or use Crystal Light (avoid red colored flavoring).
