Oraltag (iohexol) is a radiographic contrast agent indicated for use in opacification of the gastrointestinal tract during computed tomography (CT) of the abdomen and pelvis to opacify bowel loops and delineate between normal loops and adjacent organs or areas of suspected pathology. Common side effects of Oraltag include:

The adult dose of Oraltag is 4.5 g to 9 g iodine (1 to 2 bottles of prepared solution) administered orally. The volume of prepared solution to administer is 500 mL to 1000 mL. Oraltag may interact with other drugs. Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant or plan to become pregnant before using Oraltag; it is unknown how it would affect a fetus. Iohexol administered intravenously passes into breast milk, however, it is unknown if iohexol administered orally passes into breast milk. Consult your doctor before breastfeeding.

Our Oraltag (iohexol) for Oral Solution Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

In studies involving 44 adult and 69 pediatric patients who received oral and intravenous iohexol for CT examinations of the abdomen, two reports of vomiting (2%) were noted.

Postmarketing Experience

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

The following adverse reactions have been reported following oral administration of the dilute, hypotonic solutions of iohexol (9 mgI/mL to 21 mgI/mL):

  • Gastrointestinal: nausea, diarrhea
