Colonoscopy Bowel Preparation Instructions


(Afternoon Appointment)

Please read all instructions and get prescription filled at least three (3) days before your colonoscopy examination.

You should have:

  • A prescription for 2 sachets of Picoprep, to be obtained from your pharmacy-drink to clean the bowel
  • Bowel preparation instructions (this sheet)
  • A pamphlet explaining colonoscopy
  • A hospital patient information booklet, and forms to be completed and sent to the hospital

ON THE DAY BEFORE THE EXAMINATION:

  • Start taking clear fluids only, no solid food, milk or milk products are allowed. This is all you can have for the day prior to, and on the day of the colonoscopy

Clear fluids include:

  • strained fruit juices without pulp (apple, white grape, orange etc)
  • water, tea, coffee
  • clear broth/soup or Oxo
  • All of the following but not coloured red or purple -soft drinks & flavoured cordials -plain jelly(without added fruits or toppings) -clear ice blocks

At 7pm (the evening before your procedure day):

  • Add 1 sachet of picoprep to 125ml of cold water and drink

OR

  • Half fill 3 glasses with lemonade or ginger ale, and divide picoprep equally into each glass and drink.

AFTER THIS

  • Immediately drink one full glass (250 mls) of clear fluid (as listed above), water or ginger ale. Follow this with at least 3 more glasses, the more the better.

At 7am (the day of your procedure):

  • Mix 2nd sachet of picoprep as above and repeat the process.
  • It can make it easier to take the preparation if you chill the mixture, drink it through a straw, or suck barley sugars. It can also be mixed with lemonade or honey. Keep drinking as much water as possible.

IT IS VERY IMPORTANT THAT YOU KEEP DRINKING WATER (OR OTHER CLEAR FLUIDS) UP UNTIL 4 HOURS PRIOR TO YOUR APPOINTMENT TIME. BUT HAVE NOTHING TO EAT OR DRINK IN THE 4 HOURS BEFORE YOUR APPOINTMENT

  • High quality colonoscopic examination can only be achieved if the colon is clear. For this reason, you are asked to follow this regime of bowel clean out.
  • Do not exceed the doses given in the instructions.
  • The picoprep preparation often works within 30 minutes, but may take as long as 6 hours. It may cause multiple urgent bowel movements, so remain within easy reach of toilet facilities.
  • The aim of this preparation is to have you passing clear, light, straw coloured water out of your bowel. If it is muddy, or solid, you may need an enema, so please report on time for your examination. Expect to be at the hospital for at least 2 hours, but delays may occur and your stay may be longer.
    • If you are a diabetic or you are on anticoagulants i.e. warfarin – you will need further instructions and you may need to be monitored by your GP before your procedure
    • If you are on aspirin (or related eg Cartia), don’t take this on morning of colonoscopy
    • If you are on iron supplements, stop these 1 week before the colonoscopy

REMEMBER:

For 24 hours after the procedure, you cannot:

  • DRIVE
  • DRINK ALCOHOL
  • OPERATE ANY HEAVY MACHINERY
  • RIDE ON PUBLIC TRANSPORT ALONE
  • SIGN ANY LEGAL DOCUMENTS
  • MAKE ANY IMPORTANT DECISIONS.
