Trovafloxacin Levels and Effects while Breastfeeding
Summary of Use during Lactation
No information is available on the clinical use of trovafloxacin during breastfeeding; however, amounts in breastmilk appear to be low. 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,[3] but insufficient data exist to prove or disprove this assertion. Use of trovafloxacin is acceptable in nursing mothers with monitoring of the infant for possible effects on the gastrointestinal flora, such as diarrhea or candidiasis (thrush, diaper rash). However, it is preferable to use an alternate drug for which safety information is available.
Drug Levels
Maternal Levels. The manufacturer reports that trovafloxacin was found in the breast milk of three lactating subjects. The average measurable breastmilk concentration was 0.8 mcg/mL (range 0.3 to 2.1 mcg/mL) after a single intravenous alatrofloxacin dose equivalent to 300 mg of trovafloxacin. Further details on the study are not available.
Infant Levels. Relevant published information was not found as of the revision date.
