Gastrografin (diatrizoate meglumine and diatrizoate sodium solution USP) is a palatable lemon-flavored, water-soluble iodinated radiopaque contrast medium for oral or rectal administration used for radiographic examination of segments of the gastrointestinal tract and as an adjunct to contrast enhancement in CT of the torso.
Bracco advises users that serious or anaphylactoid reactions that may occur with intravascular administration of radiopaque contrast agents – theoretically possible following administration by other routes. Patients at increased risk include those with a history of a previous reaction to a contrast medium, patients with a known sensitivity to iodine per se, and patients with a known clinical hypersensitivity (bronchial asthma, hay fever, and food allergies).
