Safety of Augmentin During Breastfeeding

Augmentin (amoxicillin/clavulanic acid) is safe to use during breastfeeding and is recommended as an appropriate antibiotic option for lactating mothers. 1

Evidence for Safety

  • Amoxicillin/clavulanic acid is specifically recommended for breastfeeding mothers in clinical practice guidelines, indicating its established safety profile 1
  • The FDA drug label acknowledges that ampicillin-class antibiotics (including amoxicillin) are excreted in breast milk but does not contraindicate its use during breastfeeding 2
  • While small amounts of the drug are transferred to breast milk, the amount that an infant would ingest is significantly less than therapeutic pediatric doses 3

Clinical Considerations

  • In a prospective study comparing amoxicillin/clavulanic acid to amoxicillin alone in breastfeeding women, adverse effects in infants were generally minor and self-limiting 3
  • The rate of adverse effects in infants may increase with higher maternal dosages, but these effects typically don't necessitate interruption of breastfeeding 3
  • Potential infant side effects to monitor for include:
    • Mild gastrointestinal disturbances 4
    • Changes in stool consistency 3

Recommendations for Clinical Practice

  • When prescribing Augmentin to breastfeeding mothers:
    • Use the lowest effective dose for the shortest duration needed 1
    • Advise mothers to monitor their infant for potential side effects such as diarrhea or changes in feeding patterns 3
    • Reassure mothers that most antibiotics, including amoxicillin/clavulanic acid, are compatible with breastfeeding 5

Alternative Options

  • If concerns exist about using amoxicillin/clavulanic acid, other antibiotics considered safe during breastfeeding include:
    • Amoxicillin alone (which may have a lower rate of infant side effects) 3
    • Cephalosporins 5
    • Erythromycin or azithromycin 1

Important Considerations

  • The benefits of treating maternal infection generally outweigh the minimal risks to the breastfed infant 6
  • Temporary interruption of breastfeeding is usually not necessary and can disrupt the nursing relationship 5
  • Most commonly used antibiotics, including Augmentin, are relatively safe for breastfed babies as the dose received via milk is generally small 7
