Is intravascular contrast material safe for use in women who are breast feeding?
Yes. Less than 1% of administered iodinated contrast material or gadolinium-based contrast material is excreted in breast milk, and <1% of the contrast material ingested by infants through breast-feeding is absorbed through the gastrointestinal tract. Furthermore, direct toxicity or allergic sensitization or reaction in infants to absorbed contrast material has not been reported. If the mother has concerns about any potential ill effects to her infant, she may express and discard breast milk for 12 to 24 hours after having received contrast material. In anticipation of this, the mother may use a breast pump to obtain and save breast milk during the 24 hours prior to receiving contrast material.
