🩺 Clinical
Meropenem and vaborbactam injection is used to treat serious urinary tract infections . Meropenem is in a class of medications called carbapenem antibiotics. It works by killing bacteria. Vaborbactam is in a class of medications called beta-lactamase inhibitors. It works by preventing bacteria from destroying meropenem. Antibiotics such as meropenem and vaborbactam injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE VABOMERE (meropenem and vaborbactam) is a combination of meropenem, a penem antibacterial, and vaborbactam, a beta-lactamase inhibitor, indicated for the treatment of patients 18 years and older with complicated urinary tract infections (cUTI) including pyelonephritis caused by designated susceptible bacteria. ( 1.1 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of VABOMERE and other antibacterial drugs, VABOMERE should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.
( 1.2 ) 1.1. Complicated Urinary Tract Infections (cUTI), including Pyelonephritis VABOMERE ® is indicated for the treatment of patients 18 years of age and older with complicated urinary tract infections (cUTI) including pyelonephritis caused by the following susceptible microorganisms: Escherichia coli , Klebsiella pneumoniae , and Enterobacter cloacae species complex. 1.2.
Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of VABOMERE and other antibacterial drugs, VABOMERE should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

⛔ Contraindications ▾
4 CONTRAINDICATIONS VABOMERE is contraindicated in patients with known hypersensitivity to any components of VABOMERE (meropenem and vaborbactam), or to other drugs in the same class or in patients who have demonstrated anaphylactic reactions to beta-lactam antibacterial drugs [see Warnings and Precautions (5.1) ] . Known hypersensitivity to the components of VABOMERE (meropenem and vaborbactam) or anaphylactic reactions to beta-lactams. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypersensitivity reactions were reported with the use of VABOMERE. Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients receiving beta-lactam antibacterial drugs. Discontinue infusion if signs of acute hypersensitivity occur.
( 5.1 ) Seizures and other adverse Central Nervous System experiences have been reported during treatment with meropenem, a component of VABOMERE. ( 5.2 ) Rhabdomyolysis: If signs or symptoms of rhabdomyolysis are observed, discontinue VABOMERE and initiate appropriate therapy. ( 5.3 ) Clostridioides difficile -associated diarrhea has been reported with nearly all systemic antibacterial agents, including VABOMERE.
Evaluate patients if diarrhea occurs. ( 5.4 ) Co-administration of meropenem with valproic acid or divalproex sodium reduces the serum concentration of valproic acid potentially increasing the risk of breakthrough seizures. ( 5.5 , 7.1 )
5.1Hypersensitivity Reactions Hypersensitivity reactions were reported in patients treated with VABOMERE in the clinical trials [see Adverse Reactions (6.1) ] . Serious and occasionally fatal hypersensitivity (anaphylactic) reactions and serious skin reactions have been reported in patients receiving therapy with beta-lactam antibacterial drugs. These reactions are more likely to occur in individuals with a history of sensitivity to multiple allergens.
There have been reports of individuals with a history of penicillin hypersensitivity who have experienced severe hypersensitivity reactions when treated with another beta-lactam antibacterial drug. Before initiating therapy with VABOMERE, it is important to inquire about previous hypersensitivity reactions to penicillins, cephalosporins, other beta-lactam antibacterial drugs, and other allergens. If an allergic reaction to VABOMERE occurs, discontinue the drug immediately.
5.2Seizure Potential Seizures and other adverse Central Nervous System (CNS) experiences have been reported during treatment with meropenem, which is a component of VABOMERE. These experiences have occurred most commonly in patients with CNS disorders (e.g., brain lesions or history of seizures) or with bacterial meningitis and/or compromised renal function [see Adverse Reactions (6.1) and Drug Interactions (7.1) ] . Close adherence to the recommended dosage regimens is urged, especially in patients with known factors that predispose to convulsive activity.
Continue anti-convulsant therapy in patients with known seizure disorders. If focal tremors, myoclonus, or seizures occur, evaluate neurologically, place on anti-convulsant therapy if not already instituted, and reexamine the dosage of VABOMERE to determine whether it should be decreased or discontinued.
5.3Rhabdomyolysis Rhabdomyolysis has been reported with the use of meropenem, a component of VABOMERE [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 VABOMERE and initiate appropriate therapy.
5.4Clostridioides difficile -associated Diarrhea Clostridioides difficile -associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including VABOMERE, 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 isolates 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, o…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. VABOMERE was evaluated in a Phase 3 comparator-controlled clinical trial in cUTI, including pyelonephritis, which included 272 patients treated with VABOMERE and 273 patients treated with the comparator piperacillin/tazobactam 4.5 grams (piperacillin 4 g/tazobactam 0.5 g) every 8 hours.
After a minimum of 15 doses of IV therapy, patients could be switched to oral levofloxacin (500 mg daily every 24 hours) to complete the treatment course. Mean duration of IV therapy was 8 days in both treatment groups. Mean duration of IV and oral therapy was 10 days; patients with baseline bacteremia could receive up to 14 days of treatment.
The mean age of patients treated with VABOMERE was 53 years (range 18 to 92 years), and 32% of patients were 65 years of age or older. Patients were predominantly female (66.5%) and White (93.4%). Most patients were enrolled in Europe (89.7%).
Serious Adverse Reactions and Adverse Reactions Leading to Discontinuation Treatment was discontinued due to adverse reactions in 2.9% (8/272) of patients receiving VABOMERE and in 5.1% (14/273) of patients receiving piperacillin/tazobactam. Most common adverse reactions resulting in discontinuation of VABOMERE included hypersensitivity, 1.1% (3/272) and infusion-related reactions, 0.7% (2/272). Death occurred in 2 (0.7%) patients who received VABOMERE and in 2 (0.7%) patients who received piperacillin/tazobactam.
Common Adverse Reactions The most frequently reported adverse reactions (3% or greater) in patients receiving VABOMERE in the Phase 3 cUTI trial were headache, phlebitis/infusion site reactions, and diarrhea. Table 3 provides adverse reactions occurring in 1% or greater of patients receiving VABOMERE in the Phase 3 cUTI trial.

7 DRUG INTERACTIONS Hormonal Contraceptives: Effectiveness may be reduced; use an effective alternative non-hormonal form of contraception or additional contraceptive method. ( 7.4 , 12.3 )
7.1Valproic Acid Case reports in the literature have shown that co-administration of carbapenems, including meropenem, to patients receiving valproic acid or divalproex sodium results in a reduction in valproic acid concentrations. The valproic acid concentrations may drop below the therapeutic range as a result of this interaction, therefore increasing the risk of breakthrough seizures. Although the mechanism of this interaction is unknown, data from in vitro and animal studies suggest that carbapenems may inhibit the hydrolysis of valproic acid's glucuronide metabolite (VPA-g) back to valproic acid, thus decreasing the serum concentrations of valproic acid.
If administration of VABOMERE is necessary, then supplemental anti-convulsant therapy should be considered [see Warnings and Precautions (5.5) ] .
7.2Probenecid Probenecid competes with meropenem for active tubular secretion, resulting in increased plasma concentrations of meropenem. Co-administration of probenecid with VABOMERE is not recommended [see Clinical Pharmacology (12.3) ].
7.3Potential for VABOMERE to Affect Other Drugs When administering VABOMERE concomitantly with medicinal products that are predominantly metabolized by CYP1A2, CYP3A4, CYP2C, and/or are substrates of P-gp transporters, there is a potential risk of interaction which may result in decreased plasma concentrations and activity of the co-administered drug(s) [see Clinical Pharmacology (12.3) ]. When VABOMERE is concomitantly administered with the substrates of CYP1A2, CYP3A4, CYP2C, and/or P-gp, refer to the prescribing information for these concomitant medications for guidance on need for dosage adjustments and/or need for frequent drug level monitoring when administered with a weak CYP inducer(s).
When administering VABOMERE concomitantly with medicinal products that are substrate of OAT3 transporters, there is a potential risk of interaction which may result in increased plasma concentrations and activity of the co-administered drug(s) [see Clinical Pharmacology (12.3) ]. When VABOMERE is concomitantly administered with OAT3 substrate(s), refer to the prescribing information for these concomitant medication(s) for guidance on need for dosage adjustments and/or need for frequent drug level monitoring when administered with an OAT3 inhibitor(s).
7.4Hormonal Contraceptives Hormonal contraceptives (e.g., combined oral contraceptives containing a progestin and an estrogen) are metabolized by CYP3A and other pregnane X receptor (PXR)-regulated enzymes. Therefore, the blood concentration and the effectiveness of hormonal contraceptives may be reduced when used with VABOMERE [see Clinical Pharmacology (12.3) ] . Effective alternative non-hormonal forms of contraception or additional contraceptive methods are recommended for patients taking hormonal contraceptives when treated concomitantly with VABOMERE [see Use in Specific Populations (8.3) and Clinical Pharmacology (12.3) ].
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Fetal malformations were observed in vaborbactam-treated rabbits, therefore advise pregnant women of the potential risks to the fetus. There are insufficient human data to establish whether there is a drug-associated risk of major birth defects or miscarriages with VABOMERE, meropenem, or vaborbactam in pregnant women. Malformations (supernumerary lung lobes, interventricular septal defect) were observed in offspring from pregnant rabbits administered intravenous vaborbactam during the period of organogenesis at doses approximately equivalent to or above the maximum recommended human dose (MRHD) based on plasma AUC comparison.
The clinical relevance of the malformations is uncertain. No similar malformations or fetal toxicity were observed in offspring from pregnant rats administered intravenous vaborbactam during organogenesis or from late pregnancy and through lactation at a dose equivalent to approximately 1.6 times the MRHD based on body surface area comparison [see Data ] . No fetal toxicity or malformations were observed in pregnant rats and cynomolgus monkeys administered intravenous meropenem during organogenesis at doses up to 1.6 and 1.2 times the MRHD based on body surface area comparison, respectively.
In rats administered intravenous meropenem in late pregnancy and during the lactation period, there were no adverse effects on offspring at doses equivalent to approximately 1.6 times the MRHD based on body surface area comparison [see Data ]. The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Data Animal Data Meropenem Reproductive studies have been performed with meropenem in rats at doses of up to 1000 mg/kg/day and in cynomolgus monkeys at doses of up to 360 mg/kg/day (on the basis of body surface area comparisons, approximately 1.6 times and 1.2 times higher, respectively, than the MRHD of 2 grams every 8 hours). These studies revealed no evidence of harm to the fetus due to meropenem, although there were slight changes in fetal body weight at doses of 250 mg/kg/day (equivalent to approximately 0.4 times the MRHD of 2 grams every 8 hours based on body surface area comparison) and above in rats.
In a published study 1 , meropenem administered to pregnant rats from Gestation Day 6 to Gestation Day 17, was associated with mild maternal weight loss at all doses, but did not produce malformations or fetal toxicity. The no-observed-adverse-effect-level (NOAEL) for fetal toxicity in this study was considered to be the high dose of 750 mg/kg/day (equivalent to approximately 1.2 times the MRHD based on body surface area comparison). In a peri-postnatal study in rats described in the published literature 1 , intravenous meropenem was administered to dams from Gestation Day 17 until Postpartum Day 21.
There were no adverse effects in the dams and no adverse effects in the first generation offspring (including developmental, behavioral, and functional assessments and reproductive parameters) except that female offspring exhibited lowered body weights which continued during gestation and nursing of the second generation offspring. Second generation offspring showed no meropenem-related effects. The NOAEL value was considered to be 1000 mg/kg/day (approximately 1.6 times the MRHD based on body surface area comparisons).
Vaborbactam In a rat embryo-fetal toxicology study, intravenous administration of vaborbactam during Gestation Days 6-17 showed no evidence of maternal or embryofetal toxicity at doses up to 1000 mg/kg, which is equivalent to approximately 1.6 times the MRHD based on body surface area comparisons. In the rabbit, intravenous administration of vaborbactam during Gestation Days 7–19 at doses up to 1000 mg/kg/day (approximately 5 times the M…

No fetal toxicity or malformations were observed in pregnant rats and cynomolgus monkeys administered intravenous meropenem during organogenesis at doses up to 1.6 and 1.2 times the MRHD based on body surface area comparison, respectively.
In rats administered intravenous meropenem in late pregnancy and during the lactation period, there were no adverse effects on offspring at doses equivalent to approximately 1.6 times the MRHD based on body surface area comparison [see Data ]. The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Data Animal Data Meropenem Reproductive studies have been performed with meropenem in rats at doses of up to 1000 mg/kg/day and in cynomolgus monkeys at doses of up to 360 mg/kg/day (on the basis of body surface area comparisons, approximately 1.6 times and 1.2 times higher, respectively, than the MRHD of 2 grams every 8 hours). These studies revealed no evidence of harm to the fetus due to meropenem, although there were slight changes in fetal body weight at doses of 250 mg/kg/day (equivalent to approximately 0.4 times the MRHD of 2 grams every 8 hours based on body surface area comparison) and above in rats.
In a published study 1 , meropenem administered to pregnant rats from Gestation Day 6 to Gestation Day 17, was associated with mild maternal weight loss at all doses, but did not produce malformations or fetal toxicity. The no-observed-adverse-effect-level (NOAEL) for fetal toxicity in this study was considered to be the high dose of 750 mg/kg/day (equivalent to approximately 1.2 times the MRHD based on body surface area comparison). In a peri-postnatal study in rats described in the published literature 1 , intravenous meropenem was administered to dams from Gestation Day 17 until Postpartum Day 21.
There were no adverse effects in the dams and no adverse effects in the first generation offspring (including developmental, behavioral, and functional assessments and reproductive parameters) except that female offspring exhibited lowered body weights which continued during gestation and nursing of the second generation offspring. Second generation offspring showed no meropenem-related effects. The NOAEL value was considered to be 1000 mg/kg/day (approximately 1.6 times the MRHD based on body surface area comparisons).
Vaborbactam In a rat embryo-fetal toxicology study, intravenous administration of vaborbactam during Gestation Days 6-17 showed no evidence of maternal or embryofetal toxicity at doses up to 1000 mg/kg, which is equivalent to approximately 1.6 times the MRHD based on body surface area comparisons. In the rabbit, intravenous administration of vaborbactam during Gestation Days 7–19 at doses up to 1000 mg/kg/day (approximately 5 times the MRHD based on AUC exposure comp…
🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of VABOMERE in pediatric patients (younger than 18 years of age) has not been established. Studies of VABOMERE have not been conducted in patients younger than 18 years of age.
🧓 Geriatric Use ▾
8.5Geriatric Use Of the 272 patients treated with VABOMERE in the Phase 3 cUTI trial, 48 (18%) patients were 65 years of age and older, while 39 (14%) patients were 75 years of age and older. No overall differences in safety or effectiveness were observed between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Meropenem, a component of VABOMERE, is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with renal impairment.
Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Population pharmacokinetic (PK) analysis found no clinically relevant change in pharmacokinetic parameters in elderly patients. No dosage adjustment based on age is required.
Dosage adjustment for elderly patients should be based on renal function [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3) ] .
🆘 Overdosage ▾
10 OVERDOSAGE In the event of overdose, discontinue VABOMERE and institute general supportive treatment. Meropenem and vaborbactam can be removed by hemodialysis. In subjects with end-stage renal disease (ESRD) administered meropenem 1 gram and vaborbactam 1 gram, the mean total recovery in dialysate following a hemodialysis session was 38% and 53% of the administered dose of meropenem and vaborbactam, respectively.
No clinical information is available on the use of hemodialysis to treat VABOMERE overdosage.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action VABOMERE is an antibacterial drug [see Microbiology (12.4) ] .
12.2Pharmacodynamics Similar to other beta-lactam antibacterial drugs, the percentage of time of a dosing interval that unbound plasma concentration of meropenem exceeds the meropenem-vaborbactam minimum inhibitory concentration (MIC) against the infecting organism has been shown to best correlate with efficacy in animal and in vitro models of infection. The ratio of the 24-hour unbound plasma vaborbactam AUC to meropenem-vaborbactam MIC is the index that best predicts efficacy of vaborbactam in combination with meropenem in animal and in vitro models of infection.
Cardiac Electrophysiology At a dose of 1 and 3 times the maximum approved recommended dose, Vabomere (meropenem and vaborbactam) does not prolong the QT interval to any clinically relevant extent.
12.3Pharmacokinetics Pharmacokinetic (PK) Parameters The mean PK parameters of meropenem and vaborbactam in healthy adults with normal renal function after single and multiple 3-hour infusions of VABOMERE 4 grams (meropenem 2 grams and vaborbactam 2 grams) administered every 8 hours are summarized in Table 4. The PK parameters of meropenem and vaborbactam were similar for single and multiple dose administration of VABOMERE.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Serious Allergic Reactions Advise patients that allergic reactions, including serious allergic reactions, could occur and that serious reactions require immediate treatment. Ask patient about any previous hypersensitivity reactions to VABOMERE (meropenem and vaborbactam), penicillins, cephalosporins, other beta-lactams, or other allergens [see Warnings and Precautions (5.1) ] . Seizures Patients receiving VABOMERE on an outpatient basis must be alerted of adverse events such as seizures, delirium, headaches and/or paresthesias that could interfere with mental alertness and/or cause motor impairment.
Until it is reasonably well established that VABOMERE is well tolerated, patients should not operate machinery or motorized vehicles [see Warnings and Precautions (5.2) ] . Potentially Serious Diarrhea Counsel patients that diarrhea is a common problem caused by antibacterial drugs including VABOMERE, which usually ends when the antibacterial drug is discontinued. Sometimes after starting treatment with antibacterial drugs, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibacterial drug.
If this occurs, patients should contact their physician as soon as possible [see Warnings and Precautions (5.4) ] . Interaction with Valproic Acid Counsel patients to inform their physician if they are taking valproic acid or divalproex sodium. Valproic acid concentrations in the blood may drop below the therapeutic range upon co-administration with VABOMERE.
If treatment with VABOMERE is necessary and continued, alternative or supplemental anti-convulsant medication to prevent and/or treat seizures may be needed [see Warnings and Precautions (5.5) ] . Interaction with Hormonal Contraceptives Advise patients that administration of VABOMERE may reduce the efficacy of hormonal contraceptives. Instruct patients to use effective alternative or back-up methods of contraception (such as condoms and spermicides) during treatment with VABOMERE [see Drug Interactions (7.4) and Use in Specific Populations (8.3) ] .
Antibacterial Resistance Counsel patients that antibacterial drugs, including VABOMERE, should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When VABOMERE is prescribed to treat a bacterial infection, tell patients that although it is common to feel better early in the course of therapy, take the medication exactly as directed.
Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by VABOMERE or other antibacterial drugs in the future [see Warnings and Precautions (5.8) ] .
