Colonoscopy Preparation Under 60 (Picolax)

Dear Patient,

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:

  1. A detailed referral from your general practitioner. When scheduling your appointment, please fax this referral to 02-6778050.
  2. Any relevant medical form or laboratory results.
  3. 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.
