Progestin

Very Low Risk for breastfeeding


Safe. Compatible.
Not risky for breastfeeding or infant.

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.

Alternatives

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

Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
It is not intended to replace the relationship you have with your doctor but to compound it.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
