Poorly safe. Evaluate carefully.
Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives).

Stupor, flatulence or vomiting have been described. Theoretical risk though never reported of bone marrow toxicity. Use only if necessary. Avoid any use during neonatal period.

Be aware of the possibility of false negative results of bacterial cultures when the mother is on antibiotics.
