The Sutab Bow Kit includes a 16-ounce container and two bottles of pills, with each bottle containing 12 pills. Prior to your colonoscopy, you need to follow a clear liquid diet for at least 30 hours. On the day before the procedure, between 6 and 7 PM, open one bottle of Sutab and fill the container with a clear liquid of your choice. Take each pill with a sip of clear liquid and then drink two more 16-ounce containers of any clear liquid within the next hour. Five hours before the procedure, open the second bottle of Sutab, fill the container with a clear liquid to the fill line, and swallow each pill with a sip of clear liquid over 15 minutes. Once again, drink two more 16-ounce containers of any clear liquid. Expect diarrhea to continue for several hours, so it's important to stay near a restroom.
