Ofloxacin Levels and Effects while Breastfeeding
Summary of Use during Lactation
Ofloxacin appears in breastmilk in low levels. 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 the small amounts of fluoroquinolones in milk. Insufficient data exist to prove or disprove this assertion. Developmental problems have been reported in two infants exposed to ofloxacin in breastmilk, but their mothers were also exposed to several drugs during pregnancy and during breastfeeding, so the problems cannot necessarily be attributed to ofloxacin. Use of ofloxacin is acceptable in nursing mothers with monitoring of the infant for possible effects on the flora, such as diarrhea or candidiasis (thrush, diaper rash). . Avoiding breastfeeding for 4 to 6 hours after a dose should decrease the exposure of the infant to ofloxacin in breastmilk.
Maternal use of an ear drop or eye drop that contains ofloxacin presents negligible risk for the nursing infant. To substantially diminish the amount of drug that reaches the breastmilk after using eye drops, place pressure over the tear duct by the corner of the eye for 1 minute or more, then remove the excess solution with an absorbent tissue.
Maternal Levels. Ten lactating women (time postpartum not stated) were given ofloxacin 400 mg orally every 12 hours for 3 doses. Milk ofloxacin was measured after the third dose. The highest levels averaging 2.41 mg/L occurred 2 hours after the dose. Average milk levels then fell as follows: 1.91 mg/L at 4 hours; 1.25 mg/L at 6 hours; 0.64 mg/L at 9 hours; 0.29 mg/L at 12 hours; and 0.05 mg/L at 24 hours after the dose. Using the peak milk level data from this study, an exclusively breastfed infant would receive an estimated maximum of 0.36 mg/kg daily with this maternal dosage regimen.

Effects in Breastfed Infants
Ofloxacin was used as part of multidrug regimens to treat two pregnant women with multidrug-resistant tuberculosis, one throughout pregnancy and postpartum and the other postpartum only. The infants were breastfed (extent and duration not stated). At age 4.6 and 5.1 years, the children were developing normally except for a mild speech delay in one and hyperactivity in the other.
