Summary of Use during Lactation

No information is available on the use of delafloxacin during breastfeeding. Fluoroquinolones have traditionally not been used in infants because of concern about adverse effects on the infants' developing joints. However, recent studies indicate little risk.[1,2] The calcium in milk might prevent absorption of fluoroquinolones in milk,[3] but insufficient data exist to prove or disprove this assertion. Use of delafloxacin is acceptable in nursing mothers. However, it is preferable to use an alternate drug for which safety information is available.
