Diatrizoic acid 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 leak into the abdominal cavity. It does not coat the stomach/bowel lining as well as barium, so it is not used commonly for this purpose. It is also used to treat Ascaris lumbricoides (roundworms).<unk>  may not actually kill Ascaris, but instead it promotes , so may relieve intestinal obstruction caused by impacted Ascaris.<unk>  is used in suspected intestinal perforation, meconium ileus, and to identify bowel-lumen communication. It should not be used to investigate tracheo-oesophageal fistula because it can cause pulmonary oedema when aspirated into respiratory system.<unk>  can dislodge sticky meconium by drawing water into intestines.<unk>  is minimally absorbed from the intestines and excreted into urinary bladder. Because of its high osmolarity it can draw water from the surrounding tissues into the intestines, thus cause dehydration in people with already small plasma volume such as infants. Because of the additives and flavouring agents,<unk>  must not be used intravascularly. This chemical must be keep away from sunlight during storage. Administration It is given orally on computed tomography of the abdomen and pelvis as 30 ml solution with 3% concentration to visualise the bowel lumen and any communications with the bowel lumen. In principle, diatrizoic acid is administered by the route most appropriate and sensible to image the structure/-s of interest (e.g., IV for blood vessels through which it is distributed and kidney–ureters–bladder that excrete it; orally or per rectally as an enema for the gastrointestinal tract). *It is given orally or by enema to image the gastrointestinal tract. *It is given by Foley catheter to image the urinary tract.
