屈螺酮

Compatible

Safe substance and/or breastfeeding is the best option.

It is a progestogen analog of spironolactone with antiandrogenic activity. Used as a contraceptive. Oral administration.

It is excreted in breast milk in a clinically insignificant amount and no problems have been reported in infants whose mothers took it. (Melka 2020, Blode 2001) 

The manufacturing laboratory considers it compatible with breastfeeding. (AEMPS 2019, FDA 2019)

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, 2013 y 2010, 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)

Alternatives

We do not have alternatives for 屈螺酮 since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
