Convulsions or neuromuscular excitability may occur when high doses are used, especially in renally impaired patients. Renal impairment. Lactation: Low concentrations of piperacillin excreted in breast milk; tazobactam unknown; use caution

Pregnancy-Lactation

Pregnancy Piperacillin and tazobactam cross placenta in humans; however, there are insufficient data with piperacillin and/or tazobactam in pregnant women to inform a drug-associated risk for major birth defects and miscarriage Animal data No fetal structural abnormalities observed in rats or mice when drug administered intravenously during organogenesis at doses 1 to 2 times and 2 to 3 times human dose of piperacillin and tazobactam, respectively; based on body-surface area (mg/m2); however, fetotoxicity in presence of maternal toxicity was observed in developmental toxicity and peri/postnatal studies conducted in rats (intraperitoneal administration prior to mating and throughout gestation or from gestation day 17 through lactation day 21) at doses < maximum recommended human daily dose based on body-surface area (mg/ m²) Lactation Piperacillin is excreted in human milk; tazobactam concentrations in human milk have not been Studied; no information available on effects of piperacillin and tazobactam on breastfed child or on milk production; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for drug and any potential adverse effects on breastfed child from therapy or from underlying maternal condition

Interactions

Interacts w/ high doses of heparin, oral anticoagulants or other drugs that affect blood coagulation or thrombocyte function. Prolongs the neuromuscular blockade of vecuronium and non-depolarising muscle relaxants. Prolongs half-lives w/ probenecid. Increased risk of methotrexate toxicity.

Mechanism of Action

Piperacillin has an antimicrobial activity against a wide range of gm-ve organisms including K. pneumoniae, P. aeruginosa, Enterobacteriaceae and against gm+ve organisms eg E. faecalis and B. fragilis. Tazobactam is a penicillanic acid sulfone derivative with beta-lactamase inhibitory properties. In combination, tazobactam enhances the activity of piperacillin against beta-lactamase-producing bacteria.
