UNII-7E1DV054LO has not been studied during breastfeeding. However, the similar drug, estradiol valerate, has been used to suppress lactation, usually in combination with testosterone. Generally, UNII-7E1DV054LO should be avoided in mothers wishing to breastfeed.

Another injection ester form of estradiol, estradiol valerate was previously used therapeutically to suppress lactation, usually in combination with testosterone.[3][4][5]A retrospective cohort study compared 371 women who received high-dose estrogen (either 3 mg of diethylstilbestrol or 150 mcg of ethinyl estradiol daily) during adolescence for adult height reduction to 409 women who did not receive estrogen. No difference in breastfeeding duration was found between the two groups, indicating that high-dose estrogen during adolescence has no effect on later breastfeeding.[6]
