Doxorubicin Levels and Effects while Breastfeeding
Summary of Use during Lactation
Most sources consider breastfeeding to be contraindicated during maternal antineoplastic drug therapy, especially anthracyclines such as doxorubicin. It might be possible to breastfeed safely during intermittent therapy with an appropriate period of breastfeeding abstinence; however, the high levels and persistence of doxorubicinol in milk make defining an appropriate abstinence interval difficult. Chemotherapy may adversely affect the normal microbiome and chemical makeup of breastmilk.
Maternal Levels. Doxorubicin, doxorubicinol and two other metabolites were detected in milk after administration of 70 mg/sq m (90 mg) of doxorubicin intravenously. Peak milk levels of 128 mcg/L of doxorubicin and 111 mcg/L of its active metabolite doxorubicinol occurred 24 hours after the dose. Both drugs were detectable in milk for at least 72 hours after the dose. Other metabolites were also detected in milk at lower levels. Using these data, the breastfed infant in this case would have received an estimated 2% of maternal weight-adjusted dosage if he had been allowed to nurse throughout the 72 hours after the dose.

Effects on Lactation and Breastmilk
A study of adolescent males who had received chemotherapy for childhood malignancies found that having received doxorubicin was associated with elevated serum prolactin concentrations.
A woman diagnosed with Hodgkin's lymphoma during the second trimester of pregnancy received 3 rounds of chemotherapy during the third trimester of pregnancy and resumed chemotherapy 4 weeks postpartum. Milk samples were collected 15 to 30 minutes before and after chemotherapy for 16 weeks after restarting. The regimen consisted of doxorubicin 40 mg, bleomycin 16 units, vinblastine 9.6 mg and dacarbazine 600 mg, all given over a 2-hour period every 2 weeks. The microbial population and metabolic profile of her milk were compared to those of 8 healthy women who were not receiving chemotherapy. The breastmilk microbial population in the patient was markedly different from that of the healthy women, with increases in Acinetobacter sp., Xanthomonadacae and Stenotrophomonas sp. and decreases in Bifidobacterium sp. and Eubacterium sp. Marked differences were also found among numerous chemical components in the breastmilk of the treated woman, most notably DHA and inositol were decreased.
