Colonoscopy, preparation using Plenvu®

Information in English how to clean your bowel with Plenvu prior to a colonoscopy.

For your upcoming colonoscopy your bowel must be empty and cleaned out with a laxative called Plenvu® . Please follow these instructions for the preparation to proceed in an optimal manner.

You can pick up Plenvu® for free at the Endoscopic Unit, Monday to Friday from 08.00 - 15.00. You can also buy Plenvu® at the pharmacy – however this will be at your own expense.

If you have any questions concerning the examination or the preparation, please don't hesitate to call us at the Endoscopic Unit, phone number 38 63 54 68 (press 3 for nurse), weekdays between 08.00 am - 03.00 pm (Friday between 09.00 am - 03.00 pm)

Diet during bowel cleansing

Efficient bowel cleansing with Plenvu® creates an unobstructed view for your doctor, creating the best conditions for a successful colonoscopy.

7 days prior to the examination

You must stop taking iron supplements, as the iron darkens the color of your stool, which makes it more difficult to examine the surroundings during the colonoscopy.

5 days prior to the examination

You must stop eating food that contains seeds and kernels as they can interfere with the camera view during the colonoscopy. (e.g. kiwis, tomatoes, grapes, grapes and wholemeal bread but also chia-, sesame-, sunflower- and flaxseeds)

If you take any medicine regularly in the morning, you can take this on the day of your examination when the bowel movements have stopped.

However, if you have diabetes you should not take your regular medicine on the day of the examination.

6 - 4 hours prior to the examination you must drink Plenvu® Dose 2, sachet A and B
