When Klean-Prep is dissolved in water, it is a bowel cleansing agent. This means it flushes everything out of your intestines (gut) through a laxative action so that they are completely empty and clean.

You have been given Klean-Prep because you are going to have one of these procedures:

  • Colonoscopy
  • Barium enema
  • Gut surgery

For all of these, it is important that your gut is clean so the procedure is more likely to be a success.


Always take Klean-Prep exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

The usual dose is up to 4 sachets. Start taking Klean-Prep the day before your hospital procedure

If you have a morning appointment at the hospital take Klean-Prep during the afternoon and evening of the day before you appointment. This will take about 4 to 6 hours altogether.

If you have an afternoon appointment, take 2 sachets on the evening before your appointment, and the rest the next morning. This takes about 2-3 hours each time.

To take Klean-prep:

  • Empty the contents of one sachet of Klean-Prep into 1 litre (1 ¾ pints) of water.
  • Stir until the solution is clear.
  • Drink 1 glassful (¼ litre or ½ pint) of Klean-Prep about every fifteen minutes until you have drunk it all.
  • Make up and take the next sachets in the same way. You should be starting to have watery bowel movements so stay near a toilet. If after three sachets you are passing only clear liquid, there is no need to take the final sachet.

What else do I need to know?

You should start opening your bowels 1 to 2 hours after starting to take Klean-Prep. If you have not had a bowel movement after taking 2 sachets, wait until you go to the toilet before you continue with Klean-Prep. If you have slept the night and still not have had any bowel movements, contact the hospital for advice.

If you take more Klean-Prep than you should, drink lots of liquids especially fruit juices.

If you forget to take Klean-Prep, take the next dose as soon as you remember. Do not take a double dose to make up for a forgotten dose.
