Is Piperacillin + Tazobactam Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Piperacillin + Tazobactam? Is Piperacillin + Tazobactam safe for nursing mother and child? Does Piperacillin + Tazobactam extracts into breast milk? Does Piperacillin + Tazobactam has any long term or short term side effects on infants? Can Piperacillin + Tazobactam influence milk supply or can Piperacillin + Tazobactam decrease milk supply in lactating mothers?

Piperacillin (see specific info) is a ureidopenicillin similar to ticarcillin (see specific info).Tazobactam is added as a beta-lactamase inhibitor with few clinical and pharmacokinetic effects similar to that of piperacillin. It is excreted into breastmilk in a clinically insignificant amount (Baier 1982, Chaplin 1982, Wyeth 2007). Because it lacks of oral bioavailability, seems difficult any pass to the infant’s plasma through the breast milk ingested, except on premature infants and immediate neonatal period, in which there may be an increased intestinal permeability. Authorized use in infants and small infants (Chen 2009). Be aware of the likelihood of false negative cultures of febrile infants whose mothers are on antibiotics, as well as the possibility of gastroenteritis due to imbalanced intestinal flora.
