Colonoscopy Preparation Instructions


Two weeks before your colonoscopy:

¨ Call your pharmacy two weeks prior to your procedure. Tell them you are ready for them to fill your prescription for the colonoscopy bowel prep kit.

¨ If you are on medications (other than aspirin) that thin your blood or if you take medications for diabetes, you will need to let your family doctor know you are planning to have a colonoscopy and ask for instructions regarding this medication.

¨ Please note that UVA performs colonoscopies at two locations. Please confirm your location by referring to your appointment reminder letter.

Five days before your colonoscopy:

¨ Start a low fiber diet. See the food list on Page 4. 

¨ Stop iron, including vitamins that contain iron.

¨ Arrange a ride home with a friend or family member.

¨ Have plenty of clear liquids available at home.  See Page 3.

¨ If you wish, buy soft toilet paper, moist wipes or external ointment.

Two days before colonoscopy:

Taking Your Prep- Do not follow directions on the bottle.  Follow directions given to you by your doctor or nurse

¨ At 8:00 am you should have two jugs. Do not combine jugs, mix them separately. Add water up to the fill line of the colonoscopy bowel prep jugs. Mix well and place in refrigerator.

¨ What You Eat, Have a light breakfast (eggs, yogurt, white toast, Ramen noodles, etc.). Avoid all cereals, fruit, seeds, nuts and meat products.

¨ After your light breakfast drink only clear liquids for the entire day. Be sure to drink at least 8 tall glasses (about 8-10 ounces each) of clear liquids throughout the day. It is important that you drink plenty of liquid during the day.  Follow the lists on Page 3. 

¨ Start drinking your first jug of bowel prep at 5:00PM. You will need to drink 8 cups (1 cup = 8oz) of prep solution every 10-15 minutes until HALF of first jug is finished. Drink at least 16 ounces of additional clear liquids before bedtime.

¨ Stay close to a bathroom. Cleaning your colon causes diarrhea.

One day before colonoscopy

¨ At 12:00 PM begin to drink the other half of your first jug of bowel prep.

¨ You will need to drink 8 cups (1 cup = 8oz) of the prep every 10-15 minutes until you have finished the other half.

¨ At 6:00 PM begin to drink the second jug.

¨ You will need to drink 8 cups (1 cup = 8oz) of the prep every 10-15 minutes until HALF of the second jug is gone.

¨ Drink only clear liquids all day. Do NOT eat any solid foods or milk products. Be sure to drink at least 12 tall glasses (about 8-10 ounces each) of clear liquids throughout the day in addition to what you drink with your bowel prep.

Day of colonoscopy:

¨ Begin drinking the rest of your second jug of prep 5 hours before you leave home. You will need to drink 8 cups (1 cup = 8oz) of prep solution every 10-15 minutes until the other HALF of you second jug is finished.

¨ Continue drinking clear liquids up to 2 hours before coming to UVA. See Page 3.

¨ Arrive 45 minutes before your scheduled appointment time with a responsible adult who will be able to accompany you home.

¨ You must bring your CPAP machine with you if you have sleep apnea

Frequently Asked Questions:

Why Is It Important To Get Cleaned Inside? Your doctor must be able to see in order to complete the colonoscopy exam. If your colon is “dirty” on the inside, your doctor may not be able to see important things like polyps or cancer.

Is My Prep Working? The bowel movement coming out should look like the fluids you are drinking – clear without many particles.  You know you are done when the bowel movement coming out is yellow, light, liquid, and clear, like urine.

What are the effects of the “bowel prep?” You will have lots of diarrhea from the bowel prep. This will start anywhere from a few minutes to 3 hours after you start your prep. Many people have bloating, abdominal discomfort, and/or nausea. Some people do not like the taste or smell of the medicine. Please do not let this get in the way of taking the medicine as directed. 

Rarely, some people throw up while taking the prep. If you throw up, stop taking the prep for 30-60 minutes. Then try taking the prep again. If you are unable to finish the bowel prep, your colon may not be clean enough for your exam.

Can I drive myself home after my colonoscopy? No. For your comfort, you will receive sedation during your procedure. You will need to have a responsible adult take you home.  He or she must be with you when you register and must remain near the facility until you are discharged. 

Why do I need my CPAP machine?  Sedation or anesthesia during your procedure is like sleeping, but much deeper.  It is very important to use your CPAP during the procedure to maximize you breathing safely.  This is true even if you rarely use your CPAP.

How long will the procedure take? The exam itself takes about 45 minutes. However, time is required to prepare you for the colonoscopy; this is why we ask you to arrive 45 minutes before your scheduled appointment time. You will also require time to recover after your exam.  Expect to spend about 2-3 hours at UVA. 

My prep hasn't started working yet. What do I do? Different people respond differently to the bowel prep. If you have waited more than 3 hours without a response, then it may not be working well. Be sure you are drinking enough fluids.  If that doesn’t work, drink the second part of your prep and continue to drink fluids. It should work eventually. Call the UVA Endoscopy Unit at 434-982-0225 after 8 am on the morning of your procedure if the medicine is still not working.
