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. WHAT GASTROGRAFIN IS USED FOR 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.
