I have allergy to iodine. Gastrografin needed for CT scan. Is it safe for me to take?

No. If you have iodine allergy, you will need to premedicate with benedryl and possibly solumedrol (methylprednisolone). You do not "need" gastrografin for your study. You can drink barium and this will be safe for you.
