Is Basiliximab safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Basiliximab. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
No information is available on the clinical use of basiliximab during breastfeeding. Because basiliximab is a large protein molecule with a molecular weight of about 144,000 Da, the amount in milk is likely to be very low.[1] It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal.[2] Until more data become available, basiliximab should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. Waiting for at least 2 weeks postpartum to resume therapy may minimize transfer to the infant.[3] The manufacturer recommends that breastfeeding be discontinued during basiliximab therapy.

“No published information” means the studies do not exist yet — not that Basiliximab is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
