Can you take elotuzumab while breastfeeding?
What LactMed says
The National Library of Medicine’s own summary, quoted in full. We do not write a verdict of our own on this question, and we do not compress theirs into a label.
No information is available on the clinical use of elotuzumab during breastfeeding. Because elotuzumab is a large protein molecule with a molecular weight of 148,100 Da the amount in milk is likely to be very low. It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal. However, elotuzumab is administered with dexamethasone and lenalidomide, two drugs that have no information on use in nursing mothers. The manufacturer recommends that women receiving elotuzumab should not breastfeed.
