Most sources consider breastfeeding to be contraindicated during maternal antineoplastic drug therapy, although the evidence for this recommendation is very weak.[1][2] Although only minimal data are available to determine an appropriate period to withhold breastfeeding, the drug's terminal half-live of 4.5 hours with normal kidney function suggests that withholding breastfeeding for at least 24 hours may be sufficient for patients receiving intermittent therapy. This period may be longer in patients with impaired kidney function. Chemotherapy may adversely affect the normal microbiome and chemical makeup of breastmilk.[3]
