Allergic reactions to any drug vary widely from patient to patient. In my experience, it is very uncommon to have an allergic reaction to gastrografin. If you have an iodine allergy, then you should avoid gastrografin. Here is link to more detail information:

Iodine allergy: Here is the fda blurb: anaphylactic reactions: anaphylactic reactions, including fatalities, have been reported with the use of gastrografin. Patients at increased risk include those with a history of a previous reaction to a contrast medium, patients with a known sensitivity to iodine, and patients with a known clinical hypersensitivity (bronchial asthma, hay fever, and food allergies). Medical p. ...Read more
Yes, but...: Reactions to contrast are usually not caused by a true allergy to iodine (which is rare). Low-ionic strength contrast should be used if you have a history of reactions to contrast, and the radiologist will give you antihistamines and corticosteroids (prednisone) before the test to help prevent a reaction. With this regimen, scans are usually very safe. Talk with the radiologist about your concerns. ...Read more
What to do if I have allergy to iodine (lugols/surg prep.) gastrografin needed for CT scan. Is it safe for me to take?
Allergy: It probably wouldn't be cross reactive with gastrograffin because the allergy is not really to the iodine atom. However, if there is concern, there are alternatives to gastrograffin. For example, a diluted barium preparation, which contains no iodine, is perfectly appropriate as a CT oral contrast agent under most circumstances ...Read more

It is used to outline the stomach and intestinal lining with x-rays of the area to determine ulcers or other abnormalities. It is white or light pink in general. ...Read more

Most commonly, barium is administered into the rectum (along with air) for barium enema.
If there is suspicion of bowel perforation, water soluble gastrografin is used instead. Gastrografin is hyperosmolar and can cause fluid shifts (fluid moves from the blood to the GI tract) and should be used with caution in hemodynamically unstable patients.
Colon is then imaged with x-rays/fluoroscopy. ...Read more
Iodine vs barium: Gastografin (diatrizoic acid) is radiocontrast agent containing iodine and may be used as an alternative to barium sulfate for medical imaging of the gastrointestinal tract, such as upper gastrointestinal series and small bowel series. It is indicated for use in patients who are allergic to barium, or in cases where the barium might be the contraindicated. ...Read more
Probably okay: Policies for different imaging facilities and departments differ, but usually CTs of the abdomen and pelvis without oral contrast are fine for interpretation. Where I work, sometimes we won't even request that oral contrast be given unless it's for very specific indications. ...Read more
You can always cancel but, you may not have too.
Most centers have some flexibility if you do.
The purpose of the exam determines if you should go ahead with it or not. You may be able to reschedule later or maybe just wait a little longer than you would have with the original appointment. Call scheduling first.
We are used to making adjustments for such reasons. ...Read more
