Rectal Preparation Instructions
CT Simulation for Radiation Therapy
Dear Patient:
To properly perform your CT simulation, it is very important that your rectum is empty. This helps us accurately plan your radiation treatment.
Please follow these instructions:
The night before your appointment
- Use one dose of Paralax®, as prescribed.
- Drink one full glass of water afterward.
On the day of your CT simulation
- Use one dose of Paralax® 2 to 4 hours before your appointment
(ideally 3 hours before). - Drink one full glass of water after using the medication.
- Try to have a bowel movement before leaving home.
Important notes
- Do not skip any dose.
- Eat light meals the day before, if possible.
- If you are unable to have a bowel movement, please still come to your appointment and inform the staff.
If you have any questions, please contact our clinic. Sincerely,
Radiation Oncology Team
