Ethinyl estradiol / levonorgestrel Breastfeeding Warnings
Combination hormonal contraceptives may affect the composition of breastmilk; however, evidence suggests in healthy, well-nourished mothers, this is not likely. Combined hormonal contraceptives might transiently negatively affect growth during the first month but are unlikely to adversely affect long-term infant growth and development. The effect on lactation largely depends on time of introduction of the combined hormonal contraceptive postpartum and the dose. Ethinyl estradiol in doses greater than 30 mcg/day can suppress lactation and lead to more supplementation and possibly earlier discontinuation of breastfeeding than nonhormonal or progestin-only contraception. Introduction of an estrogen before 3 weeks postpartum may increase the risk of thromboembolism in postpartum women. Rare cases of reversible breast enlargement in breastfed infants have been reported, mostly with estrogen doses higher than those currently used.

Expert opinion in the United States recommends postpartum breastfeeding women avoid combined hormonal contraceptives during the first 3 weeks after delivery because of concerns about the increased risk for venous thromboembolism; during the fourth week postpartum, combined hormonal contraceptives should be avoided because of concerns on breastfeeding performance. Postpartum breastfeeding women with other risk factors for venous thromboembolism generally should not use combined hormonal contraceptives 4 to 6 weeks after delivery. The World Health Organization (WHO) guidelines are more restrictive, advising that combined hormonal contraceptives be avoided in breastfeeding mothers before 42 days postpartum. The WHO guidelines assess the risks of use as greater than the benefits between 6 weeks and 6 months postpartum.
