Progesterone
Excreted into breast milk in a non-significant amount with no side-effects observed in breastfed infants of treated mothers. The plasma levels in those infants have been undetectable or very low.
During the first 6 weeks after birth, non-hormonal methods are of choice as contraceptives.
If associated to estrogens may inhibit lactation. It is recommended the use of contraceptive medication that does not contain estrogens, or, better if it contains progestogen alone.
