Read the Comment.

Antibiotic of the quinolone type, active in vitro against Pseudomonas aeruginosa, structurally related to nalidixic acid.
It has been used orally and intravenously (two daily doses) to treat urinary tract infections from Gram-negative bacteria (Shimizu M 1975).

SInce the last update we have not found published data on its excretion in breastmilk.

Low toxicity in humans has been reported (Azierta 2016).

This product has very few bibliographical references.

Until there is more published data on this drug in relation to breastfeeding, safer known alternatives may be preferable, especially during the neonatal period and in case of prematurity or glucose-6-phosphate dehydrogenase deficiency.

The possible negativity of cultures in febrile infants whose mothers take antibiotics should be taken into account, as well as the possibility of gastroenteritis due to alteration of the intestinal flora (Ito 1993).
