Colonoscopy

Preparation

  • Fasting is not necessary. High-fiber bread, cereals, linseed or fruits/vegetables with a lot of seeds should be avoided the last five days before the examination.
  • Patients should avoid iron supplements in the last seven days before the examintaion.
  • Bowel emptying through taking oral laxative solutions (an abundant bowel emptying is necessary).
  • If the patient uses anticoagulants and it is necessary to take biopsies or slinging polyps (usually), the patients should consult their doctor to ensure the safety of taking a break in the medication according to the following rules:
    • Plavix® and equivalent antiplatelet is not to be discontinued if they have been in use < 1 year, otherwise stop may be considered.
    • Pradaxa®, Xarelto® and Eliquis® must be stopped two days before the examination, earlier if renal impairment.
    • Restarted after two days if a sling resection or another examination that can cause bleeding is performed.
    • Marevan® (warfarin) is stopped five days before the examination. INR is measured an hour before the procedure and should be below 1,8. If the patient has a high risk of thrombosis (heart valve and others) low molecular weight heparin must be considered. Start with double dose of Marevan® (warfarin) the same evening.
    • Albyl-E® (Acetylsalicylic Acid) can be continued.

If it is contraindicated to discontinuate (for example dual antiplatelet agent), and there is an indication to perform the examination as soon as possible, a tailored program should be made in collaboration with the general practitioner and possibly a cardiologist/haematologist.

  • Any other medications in the morning can be taken as usual.
  • If the patient has diabetes and use insulin, an appointment early in the day can be made.
  • The bladder should be empty before the examination.
