Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Anesthetic indicated for the induction of general anesthesia in adults, infants and babies older than 6 months, children and adolescents (Braun 2020).
Intravenous administration in one to three preoperative doses.

It is excreted in human milk in a clinically non-significant amount (Esener 1992).

Its low excretion in breast milk and its rapid elimination allows breastfeeding as soon as the mother is awake, alert and able to hold her baby.

The small amount of colostrum obtained by the newborn in the first few feedings makes waiting to breastfeed after a cesarean even more superfluous.


  • Methohexital ( Safe. Compatible. Minimal risk for breastfeeding and infant.)
  • Propofol ( Safe. Compatible. Minimal risk for breastfeeding and infant.)
  • Thiopental Sodium ( Safe. Compatible. Minimal risk for breastfeeding and infant.)

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.

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.

Thank you for helping to protect and promote breastfeeding.
