Impetigo during breastfeeding
Topical fusidic acid, hydrogen peroxide or mupirocin can all be used during breastfeeding.
- is limited or no published evidence of use of these topical medicines during breastfeeding
- there is limited systemic absorption and therefore negligible levels are expected in breast milk
 
 
If systematic antibiotics are required then flucloxacillin is safe in breastfeeding (2):
- if penicillin allergic then all macrolide antibiotics can be used during breastfeeding with precautionary infant monitoring (3)
 
Clinical considerations
- care should be taken to avoid direct contact between the infant and impetigo lesion(s) and treated area.
 - if lesions are on the breast or close to the nipple, it may not be possible to feed from that breast, although this would need thorough assessment
- infant feeding support should also be sought in order to effectively maintain milk supply.
 
 - hands should be washed after applying topical preparations and before touching the infant.
