Sulfur Hexafluoride use while Breastfeeding

Summary of Use during Lactation

No published experience exists with sulfur hexafluoride during breastfeeding. The half-life of the agent is about 10 minutes and absorption of the drug by the infant is unlikely. If sulfur hexafluoride is required by the mother, it is not a reason to discontinue breastfeeding.[1] Because of the lack of information, the American College of Radiology states that temporary (~24 hours) pumping and discarding of milk may be considered.[2,3]
