5 WARNINGS AND PRECAUTIONS • Serious hypersensitivity reactions (anaphylactic/anaphylactoid) have been reported in patients receiving piperacillin and tazobactam. Discontinue piperacillin and tazobactam if a reaction occurs. ( 5.1 ) • Piperacillin and tazobactam for injection 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 injection for progressive rashes. ( 5.2 ) • Hemophagocytic lymphohistiocytosis (HLH) has been reported with the use of piperacillin and tazobactam. If HLH is suspected, discontinue piperacillin and tazobactam immediately. ( 5.3 ) • Rhabdomyolysis: If signs or symptoms of rhabdomyolysis are observed, discontinue Piperacillin and tazobactam for injection and initiate appropriate therapy. (5.4) • Hematological effects (including bleeding, leukopenia and neutropenia) have occurred. Monitor hematologic tests during prolonged therapy. ( 5.5 ) • As with other penicillins, piperacillin and tazobactam may cause neuromuscular excitability or seizures. Patients receiving higher doses, especially in the presence of renal impairment may be at greater risk. Closely monitor patients with renal impairment or seizure disorders for signs and symptoms of neuromuscular excitability or seizures. ( 5.6 ) • Nephrotoxicity in critically ill patients has been observed; the use of piperacillin and tazobactam was found to be an independent risk factor for renal failure and was associated with delayed recovery of renal function as compared to other beta-lactam antibacterial drugs in a randomized, multicenter, controlled trial in critically ill patients. Based on this study, alternative treatment options should be considered in the critically ill population. If alternative treatment options are inadequate or unavailable, monitor renal function during treatment with piperacillin and tazobactam for injection. ( 5.7 ) • Clostridioides difficile associated diarrhea: evaluate patients if diarrhea occurs. ( 5.9 ) 5.1 Hypersensitivity Adverse Reactions Serious and occasionally fatal hypersensitivity (anaphylactic/anaphylactoid) reactions (including shock) have been reported in patients receiving therapy with piperacillin and tazobactam for injection. These reactions ar...

Clinical Trials in Adult Patients During the initial clinical investigations, 2621 patients worldwide were treated with piperacillin and tazobactam in phase 3 trials. In the key North American monotherapy clinical trials (n=830 patients), 90% of the adverse events reported were mild to moderate in severity and transient in nature. However, in 3.2% of the patients treated worldwide, piperacillin and tazobactam was discontinued because of adverse events primarily involving the skin (1.3%), including rash and pruritus; the gastrointestinal system (0.9%), including diarrhea, nausea, and vomiting; and allergic reactions (0.5%).
