Pregnancy: There are no or a limited amount of data from the use of Piperacillin/Tazobactam in pregnant women.
Studies in animals have shown developmental toxicity, but no evidence of teratogenicity, at doses that are maternally toxic.
Piperacillin and tazobactam cross the placenta. Piperacillin/Tazobactam should only be used during pregnancy if clearly indicated, i.e. only if the expected benefit outweighs the possible risks to the pregnant woman and foetus.
Breast-feeding: Piperacillin is excreted in low concentrations in breast milk; tazobactam concentrations in human milk have not been studied. Women who are breast-feeding should be treated only if the expected benefit outweighs the possible risks to the woman and child.
