Pregnancy: The safe use of moxifloxacin in human pregnancy has not been established. Reversible joint injuries are described in children receiving some quinolones, however this effect has not been reported as occurring on exposed fetuses. Animal studies have shown reproductive toxicity. The potential risk for humans is unknown. Consequently, the use of moxifloxacin during pregnancy is contraindicated.
Lactation: As with other quinolones, Moxifloxacin has been shown to cause lesions in the cartilage of the weight bearing joints of immature animals. Preclinical evidence indicates that small amounts of moxifloxacin may be secreted in human milk. There is no data available in lactating or nursing women. Therefore, the use of moxifloxacin in nursing mothers is contraindicated.
