In preparing for your upcoming colonoscopy, we have put together this information packet for your convenience. Please contact us with any questions you may have.
- The Gastroenterology Institute Staff
A colonoscopy is an endoscopic examination of the large bowel ('colon') and the distal section of the small bowel. The doctor uses a fiber optic attached to a flexible tube, which is passed through the rectum. This examination allows doctors to conduct a biopsy, scan for colorectal cancer, and remove polyps.
The exam will take place at the Gastroenterology Institute on floor T1 in the Sharret Oncology Institute. Please bring:
- A detailed referral from your general practitioner. When scheduling your appointment, please fax this referral to 02-6778050.
- Any relevant medical form or laboratory results.
- An authorization from your healthcare fund. Maccabi Healthcare members should also bring their healthcare cards.
If you are taking anticoagulants, please consult your doctor regarding stopping treatment. Resuming treatment will be done after the exam.
If you are taking Clexan: If your dose is 40 mg, the last dose will be given 12 hours prior to the exam. If your dose is above 40 mg, the last dose will be given 24 hours prior to treatment.
If you are taking iron medications to treat anemia, you must stop treatment 5 days prior to the exam. If you suffer from diabetes, please change your medication dosage accordingly, based on the special diet needed for preparation of the exam. Please consult your doctor. Medications taken regularly can be taken up until two hours prior to the exam.
You must come to the exam with an accompanying person as you will be given anesthetics for the exam. You cannot drive on the day of the exam.
If you cannot make it to your scheduled appointment, please cancel the appointment as soon as possible by calling 02-5842111. Please register at the front desk 15 minutes prior to your scheduled appointment.
We do our best to maintain each appointment in a timely manner. Sometimes, certain exams take longer than needed, or the order of the exams change due to professional considerations and your wait may be longer than expected.
Cleaning Your Bowels
It is very important to clean your bowels properly in order for the colonoscopy to be successful. Clean bowels are vital to ensure the effective diagnostics. Preparation includes a special diet and bowel irrigation.

Solid foods, milk products (except what is allowed for breakfast)
|The Day of the Exam
Water only, tea with honey or sugar, clear broth – up to two hours prior to the exam
Bowel Irrigation (Meroken):
The bowel irrigation preparation can be purchased at your local pharmacy with a prescription from your doctor (3 liters). It should be taken on the day prior to your exam starting at 5 pm. You should take one cup every 15-20 minutes.
- Do not add any syrup or juice to the solution.
- You can suck on a candy or ice pop in between sips.
- You can take Pramin to avoid vomiting or nausea 15 minutes prior to beginning the irrigation and with your doctor's permission.
- Do not eat after taking the irrigation; you can drink water or other clear fluids up until 2 hours prior to the exam. (If you are also undergoing a gastroscopy, you can drink until 6 hours prior to the exam).
You are required to perform an enema two hours prior to the exam.
Remove the cover from the top. We recommend you rub some Vaseline onto the mouth. Insert it into the rectum and squeeze the contents inside. After the contents have been emptied into your rectum, wait 10 minutes before going to the bathroom. If the exam is scheduled for after 12:00 pm, you should perform another enema in the morning.
