Infant risk cannot be ruled out. Available evidence and/or expert consensus is inconclusive or is inadequate for determining infant risk when used during breastfeeding. Weigh the potential benefits of drug treatment against potential risks before prescribing this drug during breastfeeding.
Contraception: Therapy may be initiated 6 weeks postpartum in fully lactating (no formula) women or 3 weeks postpartum in partially lactating (some formula) women.
Although nonhormonal methods are preferred during breastfeeding, progestin-only contraceptives such as norethindrone are considered the hormonal contraceptives of choice during lactation. Poor to fair quality evidence indicates that norethindrone does not adversely affect the composition of milk, the growth and development of the infant or the milk supply.
