According to the American College of Radiology, the plasma half-life of intravenously administered iodinated contrast for CTs is approximately 2 hours, and less than 1% of the maternal dose is excreted into breastmilk in the first 24 hours. In addition, less than 1% of this small amount of contrast in the breastmilk is absorbed by the infant gut. Therefore, it is not recommended to interrupt breastfeeding after the lactating parent has a CT with contrast. There may be a change in the taste of the milk for a few hours after the CT, but it is not considered harmful to the child.
