(Iodide Radiopaque Agent)
The various Iodinated contrast media for imaging examinations (X-rays, CT scans) are considered compatible with breastfeeding since they are rapidly eliminated with little or no release of iodine, not metabolized and virtually not absorbed when taken by mouth. They are structurally very similar to each other and one of them is their data no or minimal excretion in milk.
Given the low lipid solubility of the iodinated contrast, less than 1% of the dose administered to the mother just passing milk.
Due to their low oral bioavailability, intestinal absorption is less than 1% of the dose that he may take the infant.
The maximum dose just getting the baby is less than 0.01% of the maternal dose, which represents less than 1% of the dose administered to a nursing practice that is a radiological contrast examination.
Most radiology scientific societies agree that after a radiological iodinated contrast examination is not necessary to wait no time to nurse.

Very Low Risk
Compatible. Not risky for breastfeeding or infant.
Moderately safe. Mild risk possible. Follow up recommended. Read the Comment.
Poorly safe. Evaluate carefully. Use a safer alternative. Read the Comment.
Very High Risk
Not recommended. Cessation of breastfeeding or alternative.
