💊 Profile

Fleroxacin is a fluoroquinolone antibacterial with actions and uses similar to those of ciprofloxacin, but is reported to have greater systemic bioavailability and a longer half-life. It is given orally for the treatment of susceptible infections in usual doses of 200 to 300 mg once daily. It has also been given by intravenous infusion. The incidence of adverse effects associated with fleroxacin has been relatively high.

Breast feeding.

The American Academy of Pediatrics1 states that fleroxacin is usually compatible with breast feeding. However, in a study,2 in which women were given a single 400-mg dose and breast feeding was withheld for 48 hours, it was concluded that although a breast-fed infant would only receive a moderate amount (maximum 10 mg daily), fleroxacin should not be used in breast-feeding mothers due to the potential for adverse effects such as arthropathy in the infant.
