For best results your bowels must be cleansed. To do this you must take a laxative. There are several types of laxatives, however, for virtual colonoscopy, the laxative you will need to orally ingest is Pico Salax. A lot of bowel preparations leave a residue in the colon which can interfere with the quality of the CT.
We therefore prefer that you use our bowel preparation. However, if you have specific medical reasons why you think you shouldn't, we would be happy to speak with you. Many of your other medications could have caused this.
For instance, pain medications such as phentanyl can cause adverse affects such as constipation. Your doctor may also advise you to modify the way you take some of your other medications in the days leading up to the procedure. There are several types of purgatives. All are osmotic agents, which work by pulling water from the body into the bowel. They are safe and effective when used for appropriate patients according to the directions, but they vary from patient to patient in tolerability.
If a patient does not tolerate a purgative very well, its effect may not be complete, and the colon may not be sufficiently clean to allow a thorough examination. A commonly used purgative is polyethylene glycol PEG.
Nearly one-third of patients who could not tolerate their bowel preparation the first time do not go through with their next colonoscopy.
The second dose is dissolved in mL water 6 to 8 hours later. It is important to drink 1. Drink about mL of fluid each hour after each dose until the effects of the medication have worn off and bowel movements have stopped.
