# Do Drugs Used in Obstetric Anesthesia Interfere with Early Breastfeeding? What Determines Drug Safety in Lactation? Part 1

## TL;DR

This paper explores how drugs used in obstetric anesthesia might affect early breastfeeding and the safety of these drugs during lactation.

## Contribution

The paper introduces pharmacokinetic characteristics of drugs relevant to their transfer into mother's milk during perinatal and lactation periods.

## Key findings

- Drug transfer into fetal blood and mother's milk is a key factor in assessing drug safety during lactation.
- The risk of inhibiting lactogenesis 2 and psychological effects on mothers are important considerations.
- Formula feeding based on cow's milk poses additional risks compared to breastfeeding.

## Abstract

The issues concerning the transfer of drugs into mothers' milk and their influence on breastfed babies have not been fully studied. Assessment of the situation should include such aspects as drug transfer into fetal blood and into mother's milk, the real risk of inhibiting lactogenesis 2 in women after birth, as welI as the psychological consequences for the mother of suspending breastfeeding. The risk of feeding a newborn with formula based on cow's milk is another fateful issue.

The following paper presents the pharmacokinetic characteristics of drugs which determine their transfer level through the placenta and into mother's milk during the perinatal period and lactation.
