Receiving contrast while breastfeeding
If you will be having a CT or any other type of exam where you will receive contrast of some kind, it is SAFE for you and your baby to continue to breastfeed or pump, but there are some things that you should know.
The contrast that will be given to you will be in very small amounts in your breast milk. Your baby will only absorb the small amounts when breastfeeding so it is safe for you to breast feed after getting contrast.
It is up to you to decide if you want to stop breastfeeding for a short time after getting contrast. If you are worried about any effects contrast will have on your baby, you can stop breastfeeding from the time the first contrast is given for up to 12 to 24 hours.
There is no need to stop breastfeeding beyond 24 hours. You will need to express and discard breast milk from both breasts during that time. You may wish to use a breast pump to express milk before the contrast is given. You can then use that expressed milk to feed your baby during the time after the exam.
