-What is the best clear liquid to take?
Gatorade, which comes in many flavors, is an excellent choice as it contains electrolytes such as potassium. It is important to remember to avoid red liquids.

-Why avoid red liquids?
The color red can persist in the colon and potentially look like blood.

-One of my medications I was instructed to take the morning of my procedure is red. Can I take it?
Medications for blood pressure, heart conditions, and seizures should be taken the morning of your exam regardless of the color.

-Is there any way that I can make this taste and better?
You can try sucking on hard candy or putting it in the freezer to make a slush. You can also rinse your mouth with water or a mouthwash. Do not eat or drink anything while you are drinkning this solution.

-I feel like vomiting, what should I do?
It is important that you take your entire prep if at all possible. Remember that without a clean bowel, the doctor will not be able to adequately see the inside of your colon to complete the examination. If you do vomit the first dose, call us and have a phone number of a pharmacy that is open, in case we need to call in a prescription.

-I already have diarrhea before taking the prep, do I still have to take the laxative?
Yes, you must take the prep as directed by your doctor. Your colon is approximately 6 feet long. The entire colon must be emptied for your physician to see the colon clearly.

-I am taking the prep and already having loose, watery stool. Do I still need the rest of the prep?
Yes, you may have solid stool higher in the colon that needs to be eliminated.

-I see yellow color in the toilet bowl and a few flecks. What do I do?
If your last bowel movements were clear enough that you were able to see the bottom of the toilet, you should be fine. It is OK if you may have some flecks of material. The yellow color is a result of bile that normally colors the feces. This shouldn’t interfere with the examination.

-My bottom is sore. What can I do?
To clean the area, avoid rubbing. Gently pat with a wet washcloth. Apply Vaseline (TM), Preparation H (TM), or Desitin liberally.

-Can I drink alcoholic beverages?
We strongly suggest that you do not drink any alcoholic beverages prior to your procedure since they can cause dehydration and some wines may thin your blood.

-Can I drink any nutritional supplements?
You may drink Ensure (chocolate or vanilla) or Slim-Fast with Soy Protein/Lactose Free. These drinks are water based, not milk based.
