Piperacillin, a broad spectrum, semi-synthetic penicillin active against many gram-positive and gram-negative aerobic and anaerobic bacteria, exerts bactericidal activity by inhibition of both septum and cell wall synthesis. Tazobactam is a potent inhibitor of many beta-lactamases, including the plasmid and chromosomally mediated enzymes that commonly cause resistance to penicillins.
Piperacillin and tazobactam is contraindicated in patients with a history of allergic reactions to any of the penicillins, cephalosporins, or β -lactamase inhibitors.
Adverse events primarily involving the skin, including rash, pruritus and Purpura; the gastrointestinal system including diarrhea, Constipation, nausea, vomiting, Dyspepsia and Abdominal Pain; General disorders and administration site conditions including Fever, Injection site reaction (≤1%) and Rigors.
Piperacillin and tazobactam cross the 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. Piperacillin is excreted in human milk; tazobactam concentrations in human milk have not been studied. No information is available on the effects of piperacillin and tazobactam on the breastfed child or on milk production.
Serious hypersensitivity reactions (anaphylactic/anaphylactoid) reactions have been reported in patients receiving Piperacillin and tazobactam. Discontinue Piperacillin and tazobactam if a reaction occurs.
Piperacillin and tazobactam may cause severe cutaneous adverse reactions, such as Stevens- Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms, and acute generalized exanthematous pustulosis. Discontinue Piperacillin and tazobactam for progressive rashes.
There have been post marketing reports of overdose with piperacillin/tazobactam. The majority of those events experienced, including nausea, vomiting, and diarrhea, have also been reported with the usual recommended dosages.
