Consumer Medicine Information


This leaflet answers some common questions about Gastrografin. It does not contain all the available information. It does not take the place of talking to your doctor or radiologist.

All medicines have risks and benefits. Your doctor has weighed the risks of using this medicine against the benefits they expect it will have for you.

If you have any concerns about using this diagnostic agent, ask your doctor.

Keep this leaflet. You may need to read it again.

Gastrografin is an X-ray contrast medium that acts like an X-ray dye when X-rays of the gastrointestinal tract are being taken. It is provided as a solution for drinking or diluted for use as an enema. Gastrografin has a sweet taste. All X-ray contrast mediums, including Gastrografin, contain iodine. Just as X-rays are unable to pass through bones in your body and thus produce a ‘picture’, X-rays are unable to pass through the iodine in contrast medium. In this way, Gastrografin enables the radiologist to see the gastrointestinal tract more clearly.

Gastrografin is often used when a barium enema or meal cannot be used. It is sometimes added to barium to improve the X-ray picture.

Gastrografin is sometimes used to treat meconium ileus, a specific type of bowel blockage.

Gastrografin may also be used for CT scan (Computerised Tomography) in the abdominal region.

Gastrografin is only available in X-ray departments and X-ray practices for use in conjunction with taking X-rays.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions given, ask your doctor for help.

How much is taken/used

The actual dose of Gastrografin that is right for you will be worked out by the doctor and will depend on your age and the type of X-ray examination that is being done.

How it is taken/used

You will receive Gastrografin for drinking or diluted as an enema.

A cleansing of the bowels before the use of Gastrografin is recommended. Your doctor will advise you on this.

Adequate water and electrolyte (salt) intake should be maintained as Gastrografin may cause dehydration and electrolyte imbalance.

Gastrografin must not be given as an injection.

If you take too much (overdose)

As Gastrografin is administered in specialist centres, overdosage is unlikely. If it does happen the doctor will treat any symptoms that follow. This may involve water and salt replacement through an intravenous drip. The rare and severe side effects noted above can occur regardless of the dosage that is administered.

If in doubt it is advisable to telephone the Poisons Information Centre (Australia: 13 11 26 or New Zealand: 0800 POISON or 0800 764 766) for advice if you think that you or anyone else may have taken too much Gastrografin. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

Tell your doctor or radiologist as soon as possible if you do not feel well while you are taking Gastrografin. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Do not be alarmed by the following list of side effects. You may not experience any of them.

Ask your doctor or radiologist to answer any questions you may have.

Tell your doctor or radiologist if you notice any of the following and they worry you.

This list includes the more common side effects of your medicine:

  • diarrhoea
  • nausea and vomiting
  • existing inflammation of the bowel may temporarily worsen.
  • in case of bowel obstruction, prolonged contact of Gastrografin with the bowel can lead to bleeding due to damage of bowel tissue.

The list below includes the rare side effects of your medicine.

  • inhalation of contrast medium into the lungs and subsequent build up of fluid in the lungs
  • skin redness
  • itchy rashes

Allergic and allergy like reactions have been observed after use of X-ray contrast media such as Gastrografin.

Tell your doctor or radiologist if you notice any of the following and they worry you:

  • nausea
  • vomiting
  • mild swelling of the facelips, tongue or throat
  • conjunctivitis
  • coughing
  • itching
  • running nose
  • sneezing and hives

Tell the doctor immediately if you experience any of these reactions as it may be the first sign of developing a severe reaction. Allergy-like reactions have been reported rarely or very rarely after use of X-ray contrast media such as Gastrografin. The symptoms are usually mild and generally occur in the form of skin reactions.

The risk of allergic reactions is higher if you have a history of allergic disorders, have bronchial asthma, have previously had an allergic reaction to iodinated contrast media, or have a heart condition.

Other reactions include:

  • chest pain and pneumonia
  • sneezing
  • a sore ulcerated mouth
  • delayed reactions (e.g. fever, rash, flu-like symptoms, joint pain or itchiness) can occasionally occur and are more likely in patients who have received interleukin.
