Colonoscopy Preparation

Preparing for a colonoscopy can be extremely difficult especially when friends and family eat in front of you and you just want a bite of their food.  Depending on your preparation choice (Picolax or MoviPrep) it influences when you have to start your preparation for the colonoscopy.  MoviPrep is the day before the procedure whilst Picolax is 3 days before the procedure.  For both preparations you can take your usual medications but avoid all iron medication and any other constipating drugs for one week before the procedure.

BOTH preparations cause diarrhoea!  And both may cause stomach cramps and vomiting.  These preparations are to clean the bowel out for the colonoscopy.  If you cannot handle the pain and cramps drink the preparations more slowly over 30mins to ease the side effects and if it still persists seek medical advice from the endoscopy unit or GP (if open).

To reduce irritation from wiping use soft or moist tissue paper and apply petroleum jelly (Vaseline) to your bum before and after each visit.

With Picolax you have to start a low residue diet Day 1 (3 days before the procedure).  So if your procedure is on the Monday you start your diet on the Friday.  See the below for the list of foods and drinks you are allowed and the ones you have to avoid when following a low residue diet.

Day 2 (2 days before the procedure) you must follow a clear liquid diet.  See below for the list of drinks allowed when following a clear liquid diet.

Day 3 (day before the procedure) you have to continue the clear fluids to prevent you from becoming dehydrated.  At 8am dissolve the powder containing one sachet of Picolax with 150ml of cold water and drink.  At 4pm dissolve the powder of the second sachet of Picolax and drink.

On the day of the procedure if you are only having a colonoscopy, keep drinking clear liquids up until your appointment time to satisfy your thirst.  After your procedure you can start eating and drinking as normal again.

With the MoviPrep the preparation starts the day before the procedure.  You have to have a low residue breakfast BEFORE 8am.  After 8am follow a clear fluid diet.  To prepare the MoviPrep take one of sachet A and one of sachet B and dissolve both in one litre of luke-warm water.  Start drinking at 1pm and finish at 2pm, drink one glass every 15mins.  And do the same with the second set of sachets and drink between 6pm and 7pm.  Drink each glass as quickly as possible instead of sipping it slowly.
