Irrespective of the type of prep used (eg Picoprep or Prekit-C), both contain three sachets which are mixed with water and drunk in the 24 hours prior to your colonoscopy.
PicoPrep
PicoPrep® is recommended as it is sold as a box of three sachets. Each sachet consists of white powder that is mixed as a drink with a glass (i.e. 250ml) of water. Those having a morning colonoscopy drink their PicoPrep® at 2pm, 4pm and 6pm the day before their colonoscopy. Those having an afternoon colonoscopy drink their PicoPrep® at 6pm and 8pm (day before) and 6am (day of) their colonoscopy. Those having an evening colonoscopy drink their PicoPrep® at 6pm (day before) and 6am and 8am (day of) their colonoscopy (see Table 1).
Prep kit C
Prep Kit C® may be required to obtain a clean colon for those with chronic constipation or those who have previously not had a clean bowel preparation with conventional preps.
This kit also consists of three sachets: two small Picoprep each mixed with 250ml of water and one much larger sachet (Glycoprep-C), which is mixed with 1 Litre of water and sipped slowly over the hour.
