Warnings
Important safety information
Serious hypersensitivity reactions (anaphylactic/anaphylactoid) reactions have been reported in patients receiving piperacillin and tazobactam for injection. Discontinue piperacillin and tazobactam for injection 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 for injection. If HLH is suspected, discontinue piperacillin and tazobactam for injection 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 for injection may cause neuromuscular excitability or seizures. Patients receiving higher doses, especially in the presence of renal impairment maybe 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 for injection 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 are more likely to occur in individuals with a history of penicillin, cephalosporin, or carbapenem hypersensitivity or a history of sensitivity to multiple allergens. Before initiating therapy with piperacillin and tazobactam for injection, careful inquiry should be made concerning previous hypersensitivity reactions. If an allergic reaction occurs, piperacillin and tazobactam for injection should be discontinued and appropriate therapy instituted. 5.2 Severe Cutaneous Adverse Reactions 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. If patients develop a skin rash they should be monitored closely and piperacillin and tazobactam for injection discontinued if lesions progress. 5.3 Hemophagocytic Lymphohistiocytosis Cases of hemophagocytic lymphohistiocytosis (HLH) have been reported in pediatric and adult patients treated with piperacillin and tazobactam for injection. Signs and symptoms of HLH may include fever, rash, lymphadenopathy, hepatosplenomegaly and cytopenia. If HLH is suspected, discontinue piperacillin and tazobactam for injection immediately and institute appropriate management. 5.4 Rhabdomyolysis Rhabdomyolysis has been reported with the use of Piperacillin and tazobactam for injection [ see Adverse Reactions ( 6.2 ) ] . If signs or symptoms of rhabdomyolysis such as muscle pain, tenderness or weakness, dark urine, or elevated creatine phosphokinase are observed, discontinue Piperacillin and tazobactam for injection and initiate appropriate therapy. 5.5 Hematologic Adverse Reactions Bleeding manifestations have occurred in some patients receiving beta-lactam drugs, including piperacillin. These reactions have sometimes been associated with abnormalities of coagulation tests such as clotting time, platelet aggregation and prothrombin time, and are more likely to occur in patients with renal failure. If bleeding manifestations occur, piperacillin and tazobactam for injection should be discontinued and appropriate therapy instituted. The leukopenia/neutropenia associated with piperacillin and tazobactam for injection administration appears to be reversible and most frequently associated with prolonged administration. Periodic assessment of hematopoietic function should be performed, especially with prolonged therapy, i.e., ≥ 21 days [see Adverse Reactions ( 6.1 )] . 5.6 Central Nervous System Adverse Reactions As with other penicillins, piperacillin and tazobactam for injection may cause neuromuscular excitability or seizures. Patients receiving higher doses, especially patients with renal impairment may be at greater risk for central nervous system adverse reactions. Closely monitor patients with renal impairment or seizure disorders for signs and symptoms of neuromuscular excitability or seizures [ see Adverse Reactions ( 6.2 ) ] . 5.7 Nephrotoxicity in Critically Ill Patients The use of piperacillin and tazobactam for injection 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 [ see Adverse Reactions ( 6.1 ) ] . 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 [ see Dosage and Administration ( 2.4 ) ] . Combined use of piperacillin/tazobactam and vancomycin may be associated with an increased incidence of acute kidney injury [ see Drug Interactions ( 7.3 ) ] . 5.8 Electrolyte Effects Piperacillin and tazobactam for injection contains a total of 2.84 mEq (65 mg) of Na + (sodium) per gram of piperacillin in the combination product. This should be considered when treating patients requiring restricted salt intake. Periodic electrolyte determinations should be performed in patients with low potassium reserves, and the possibility of hypokalemia should be kept in mind with patients who have potentially low potassium reserves and who are receiving cytotoxic therapy or diuretics. 5.9 Clostridioides difficile -Associated Diarrhea Clostridioides difficile -associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including piperacillin and tazobactam for injection, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile . C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibacterial drug use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile , and surgical evaluation should be instituted as…
Who should not take Piperacillin and Tazobactam
Piperacillin and tazobactam for injection is contraindicated in patients with a history of allergic reactions to any of the penicillins, cephalosporins, or beta-lactamase inhibitors. Patients with a history of allergic reactions to any of the penicillins, cephalosporins, or beta-lactamase inhibitors. ( 4 )
Overdose — what happens if you take too much
There have been postmarketing 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. Patients may experience neuromuscular excitability or seizures if higher than recommended doses are given intravenously (particularly in the presence of renal failure) [see Warnings and Precautions ( 5.6 )] . Treatment should be supportive and symptomatic according the patient's clinical presentation. Excessive serum concentrations of either piperacillin or tazobactam may be reduced by hemodialysis. Following a single 3.375 g dose of piperacillin/tazobactam, the percentage of the piperacillin and tazobactam dose removed by hemodialysis was approximately 31% and 39%, respectively [see Clinical Pharmacology ( 12 )] .

Interactions
Piperacillin and tazobactam for injection administration can significantly reduce tobramycin concentrations in hemodialysis patients. Monitor tobramycin concentrations in these patients. ( 7.1 ) Probenecid prolongs the half-lives of piperacillin and tazobactam and should not be co-administered with piperacillin and tazobactam for injection unless the benefit outweighs the risk. ( 7.2 ) Co-administration of piperacillin and tazobactam for injection with vancomycin may increase the incidence of acute kidney injury. Monitor kidney function in patients receiving piperacillin and tazobactam for injection and vancomycin. ( 7.3 ) Monitor coagulation parameters in patients receiving piperacillin and tazobactam for injection and heparin or oral anticoagulants. ( 7.4 ) Piperacillin and tazobactam for injection may prolong the neuromuscular blockade of vecuronium and other non-depolarizing neuromuscular blockers. Monitor for adverse reactions related to neuromuscular blockade. ( 7.5 ) 7.1 Aminoglycosides Piperacillin may inactivate aminoglycosides by converting them to microbiologically inert amides. In vivo inactivation: When aminoglycosides are administered in conjunction with piperacillin to patients with end-stage renal disease requiring hemodialysis, the concentrations of the aminoglycosides (especially tobramycin) may be significantly reduced and should be monitored. Sequential administration of piperacillin and tazobactam for injection and tobramycin to patients with either normal renal function or mild to moderate renal impairment has been shown to modestly decrease serum concentrations of tobramycin but no dosage adjustment is considered necessary. In vitro Inactivation: Due to the in vitro inactivation of aminoglycosides by piperacillin, piperacillin and tazobactam for injection and aminoglycosides are recommended for separate administration. Piperacillin and tazobactam for injection and aminoglycosides should be reconstituted, diluted, and administered separately when concomitant therapy with aminoglycosides is indicated. Piperacillin and tazobactam for injection is not compatible with tobramycin for simultaneous Y-site infusion [ see Dosage and Administration ( 2.8 ) ] . 7.2 Probenecid Probenecid administered concomitantly with piperacillin and tazobactam for injection prolongs the half-life of piperacillin by 21% and that of tazobactam by 71% because probenecid inhibits tubular renal secretion of both piperacillin and tazobactam. Probenecid should not be co-administered with piperacillin and tazobactam for injection unless the benefit outweighs the risk. 7.3 Vancomycin Studies have detected an increased incidence of acute kidney injury in patients concomitantly administered piperacillin/tazobactam and vancomycin as compared to vancomycin alone [ see Warnings and Precautions ( 5.7 ) ] . Monitor kidney function in patients concomitantly administered with piperacillin/tazobactam and vancomycin. No pharmacokinetic interactions have been noted between piperacillin/tazobactam and vancomycin. 7.4 Anticoagulants Coagulation parameters should be tested more frequently and monitored regularly during simultaneous administration of high doses of heparin, oral anticoagulants, or other drugs that may affect the blood coagulation system or the thrombocyte function. [ see Warnings and Precautions ( 5.5 ) ] . 7.5 Vecuronium Piperacillin when used concomitantly with vecuronium has been implicated in the prolongation of the neuromuscular blockade of vecuronium. Piperacillin and tazobactam for injection could produce the same phenomenon if given along with vecuronium. Due to their similar mechanism of action, it is expected that the neuromuscular blockade produced by any of the non-depolarizing neuromuscular blockers could be prolonged in the presence of piperacillin. Monitor for adverse reactions related to neuromuscular blockade (see package insert for vecuronium bromide). 7.6 Methotrexate Limited data suggests that co-administration of methotrexate and piperacillin may reduce the clearance of methotrexate due to competition for renal secretion. The impact of tazobactam on the elimination of methotrexate has not been evaluated. If concurrent therapy is necessary, serum concentrations of methotrexate as well as the signs and symptoms of methotrexate toxicity should be frequently monitored. 7.7 Effects on Laboratory Tests There have been reports of positive test results using the Bio-Rad Laboratories Platelia Aspergillus EIA test in patients receiving piperacillin/tazobactam injection who were subsequently found to be free of Aspergillus infection. Cross-reactions with non- Aspergillus polysaccharides and polyfuranoses with the Bio-Rad Laboratories Platelia Aspergillus EIA test have been reported. Therefore, positive test results in patients receiving piperacillin/tazobactam should be interpreted cautiously and confirmed by other diagnostic methods. As with other penicillins, the administration of piperacillin and tazobactam for injection may result in a false-positive reaction for glucose in the urine using a copper-reduction method (CLINITEST ® ). It is recommended that glucose tests based on enzymatic glucose oxidase reactions be used.
