Minimizing infant exposure to and risks from medications while breastfeeding

Area of Science:

• Perinatal health
• Pharmacology
• Lactation science

Background:

• Breastfeeding provides significant advantages for both mothers and newborns.
• Lactating mothers often express concerns regarding medication safety and potential risks to their infants.
• Understanding drug transfer into breast milk is crucial for managing breastfeeding safety.

Purpose of the Study:

• To provide guidance on medication use during breastfeeding.
• To inform healthcare providers and mothers about drug safety in lactation.
• To support continued breastfeeding when possible.

Main Methods:

• Review of established principles of lactation and drug pharmacokinetics.
• Utilization of available resources to assess medication safety for breastfeeding.
• Development of strategies to minimize medication transfer to the infant.

Main Results:

• All medications are excreted into breast milk, but typically in minimal quantities.
• Resources exist to classify medications as contraindicated or compatible with breastfeeding.
• A systematic approach can minimize infant exposure to medications via breast milk.

Conclusions:

• Informed decisions regarding medication use can support safe breastfeeding.
• Understanding drug transfer facilitates risk-benefit assessments for medications.
• The goal should be to encourage and support mothers in continuing breastfeeding.
