Diet and Bowel Preparation Information for patients using Plenvu
The aim of this information is to help you to prepare for your endoscopy procedure (colonoscopy, flexi sigmoidoscopy or enteroscopy). Please read this thoroughly for advice on alterations needed to your diet and administration of bowel preparation medication to clean your bowel in the days leading up to your endoscopy test.
These instructions for taking your bowel preparation replace those enclosed in the packets containing Plenvu. However, it is important you read the manufacturer’s leaflet inside the packet of preparation before you take the bowel preparation. The leaflet will tell you about the preparation itself, allergies, indications for taking or not taking the preparation, the possible side effects, the effect it can have on taking oral medications – in particular medications that may affect fluid balance, and when you should consult a doctor before taking the bowel preparation.
Any usual oral medication should be taken at least two hours before starting the Plenvu to minimise the risk of flushing the medication through the gut and not being fully absorbed.
The aim of the bowel preparation is to clean your bowel so that there are clear views of the lining of your bowel during your endoscopy procedure. If you are unable to take any of the bowel preparation for any reason or your bowel preparation does not work properly it is important you contact the endoscopy unit using the contact telephone number on your endoscopy appointment letter.
Poor bowel preparation may mean that your endoscopy procedure will be stopped or may not go ahead and you will need to repeat the preparations and endoscopy test on another day.
We understand we may be asking you to get up early on the day of your test to take your second sachets of bowel preparation.
Research shows that to achieve good views during your colonoscopy procedure and reduce the risk of missing lesions or polyps it is best to take the second part of your bowel preparation 5 hours before the time of your appointment for your endoscopy test. If you feel it is impossible to get up this early to take your bowel preparation please contact endoscopy.
Important information about some of the ingredients of Plenvu: Plenvu contains aspartame, which is a source of phenylalanine which may be harmful for people with phenylketonuria (a genetic disorder affecting metabolism). It also contains ascorbate which may be harmful for people with glucose-6-phosphate dehydrogenase deficiency. Do not take Plenvu if you have phenylketonuria or glucose-6-phosphate dehydrogenase deficiency, please contact endoscopy.
The remainder of this information advises you on how to prepare in the days leading up to your endoscopy procedure. Please follow the actions below starting 7 days before the day of your appointment if you take iron medications or day 4 before for all other patients.

- Drink the bowel preparation solution through a straw
- Some people find that drinking the bowel preparation quickly, followed by a small drink of apple juice (with no pulp/bits) helps
- If you feel nauseated while taking the preparation, stop for half an hour before resuming drinking more slowly
- If you feel bloated, try walking around, sucking peppermints or drinking peppermint tea.
- Hydration is essential for effective bowel preparation. Continue to drink plenty of fluids, preferably water.
- Use a barrier cream around the anus to reduce discomfort
- Stay near a bathroom.
- If you get any side effects, talk to your doctor, pharmacist or nurse.
If you become ill or have severe abdominal pain, stop taking the bowel preparation and seek medical advice.
