Klean Prep bowel preparation

Klean Prep is a special powder you will take before you have your colonoscopy.

Klean Prep comes in a box containing 4 Sachets. It is available by prescription from your pharmacist.

The Day Before Your Test
You may have a light breakfast (e.g. tea and toast) at 08.00hrs. No further solid food should be taken after breakfast.

Drink clear fluids for the duration of the day along with your bowel prep.
Clear fluids include water, 7-up, fruit juice without pulp, black tea or coffee (no milk or sugar) and jelly.

Avoid red or purple coloured fruit juice and jelly as these can cause discolouration of the lining of the bowel.

You should commence your bowel prep as prescribed at 12 midday.

Mix each sachet with 1 litre (2 pints) of cold water and stir thoroughly until solution turns clear.
Drink each litre of Klean Prep over the duration of 1 hour or approximately 1 standard sized mug (250mls) every 15 minutes. Drinking the solution ice cold also makes the prep more palatable.

You must repeat mixing 1 sachet in 1 litre of water for a total of 4 sachets.

Make sure to drink plenty of clear fluids to prevent dehydration and keep hunger pangs at bay. This will also make the prep work more effectively.

You may experience some crampy abdominal (stomach) pains or nausea but these symptoms will improve once you start passing bowel motions.

You will most likely start passing bowel motions after completion of the 1st sachet. Stay close to toilet facilities. It is advised that you take the afternoon off from work.

Aim to have the prep completed by 18.00 hrs (6pm) so the effects will have worn off before going to bed and sleep pattern will not be effected.

It is very important to complete all of the prep otherwise the procedure cannot be performed effectively.

Vaseline or Sudocream can be applied around the back passage to prevent or soothe any discomfort.

The Day of Your Test
You must not eat or drink after 12 midnight until after your colonoscopy.
