How to prepare for your Colonoscopy

To have a successful preparation of your bowel and avoid you having to come back again, your bowel must be empty and clean. You must follow the diet set out in this leaflet and take the Senna laxative and both sachets of Picolax. You may need to have a blood test prior to starting the prep. This will be discussed with you by the Pre-Assessment nurse.

4 days before your appointment

Stop taking any medication that may cause you to become constipated for example Lomitil or Codeine Phosphate but continue to take all your usual medications.

3 days before your appointment

You must drink at least one glass of fluid every hour throughout the day, over the 3 day preparation period. If you can do this your bowel will be empty and clean and ready for your colonoscopy examination. Please avoid using Non Steroidal Anti inflammatory drugs e.g. Ibuprofen, Diclofenac from today until after the colonoscopy. You may have been asked to stop certain medications from today. The Pre Assessment nurse will confirm these with you.

Medications to stop
