One Day Bowel Preparation

Day Before Surgery


You should STOP eating all solid foods. You may have only clear liquids including fruit juices tea, coffee (without milk), water, soda, jello, broth, popsicles….no milk or milk products like ice cream.


It is important that you continue taking your prescription medicines during this time. If you take insulin on a daily basis please check with your regular practitioner about how to manage your diabetes while the bowel preparation is in progress.


You will have a prescription for a bowel preparation which needs to be mixed with water. Follow the directions on the label for mixing. Start drinking the medication by noon to give yourself plenty of time. Do not drink it quickly. If you begin to feel full or nauseous, slow down between glasses.






Some hints to help you get through:


  • Do not refrigerate medication; (even though it says to on the jug) a ½ gallon of cold fluid may give you the chills.
  • You can suck on a lemon or lime before and after each drink to cut the taste.
  • If you get bloated during the process, stop for some time, and then resume.

You should have two prescriptions for neomycin and erythromycin. You will need to take 2 pills of each at 2pm 3pm and 10pm. Check to be sure that each pill is 500mg. Nausea is a normal reaction to this medication. IF, however, you feel very sick or vomit, do not panic. Do your best; if you cannot get the pills down, don’t worry about it just finish the liquid preparation.


Do not have anything to eat or drink after midnight.


You may take your regular medicines with a small sip of water in the morning.
