Norethisterone or Nornorethindrone is a contraceptive progestogen derived from 19-northstastterone used as a single product or associated with ethinylestradiol. Oral administration daily or in intramuscular injection every 8 weeks.
It is excreted in breast milk in clinically significant amount (Betrabet 1987, Toddywalla 1980, Saxena 1977) and no problems have been observed in infants whose mothers took it. (WHO 1994, Shaaban 1991, Giner 1976, Karim 1971)
Plasma levels of these infants were undetectable or very low.(Betrabet 1987)
No alterations have been observed in the amount or composition of breast milk in mothers treated with norethindrone. (Giner 1976)

During breastfeeding progestin-only contraceptives are preferable to those combined with estrogen and, in this case, those with a lower dose of estrogen. (CDC 2016, WHO/OMS 2015, Altshuler 2015, Berens 2015, CLM 2012, Moretti 2000)
For the first 4-6 weeks postpartum, non-hormonal methods are the first choice, followed by IUDs and progestogen implants. (Berens 2015, Mwalwanda 2013, Rowe 2013, CLM 2012)
