Levonorgestrel is a progestin, and active metabolite isomer of norgestrel, both derived from nortestosterone. It is excreted in breast milk in clinically non-significant amount, and, no problems have been observed in infants whose mothers were treated. The plasma levels of these infants were very low.
Levonorgestrel and progestogens are generally considered contraceptive drugs of choice during lactation since they neither alter the quantity and composition of milk nor cause side effects on both growth of infants and the duration of breastfeeding.
Published study results have shown protection against breast bone mass loss with the use of progestin-only contraceptives.
For the first 6 weeks postpartum, non-hormonal methods are of choise. There is a debate on the role of progestin-related drugs in decreasing milk production when used before lactation has been fully established.
