Brand names: Vabomere

Carbapenem / Beta-Lactamase Inhibitor Rx

Vabomere is a drug that combines two medicines to fight certain infections. It contains meropenem, an antibacterial, and vaborbactam, which helps meropenem work better.

What it does

Vabomere treats complicated urinary tract infections (cUTIs) in adults.

Common side effects

Headache, Irritation, swelling, or pain at the IV site, Diarrhea

Key warnings

You should not take this medicine if you are allergic to any of its ingredients or to similar drugs.

How It Works

Meropenem kills bacteria by stopping them from building cell walls. Vaborbactam blocks enzymes that bacteria use to break down meropenem. This helps meropenem work more effectively against the infection.

How to Take It

Vabomere is given into your vein through an IV. You'll receive 4 grams of Vabomere (2 grams of meropenem and 2 grams of vaborbactam) every 8 hours. Each dose is infused slowly over 3 hours. Treatment usually lasts up to 14 days.

Pregnancy & Breastfeeding

Vabomere may harm your unborn baby. Talk to your doctor if you are pregnant or plan to become pregnant. It is not known if Vabomere passes into breast milk, so discuss breastfeeding with your doctor.

Missed Dose

If you miss a dose, contact your doctor or nurse right away to reschedule it. It is important to get every dose of Vabomere on time.

Storage

Store Vabomere vials at room temperature, between 68°F to 77°F.

Serious Warnings

You should not take this medicine if you are allergic to any of its ingredients or to similar drugs. Vabomere may cause seizures, especially if you have kidney problems or a history of seizures. It can also cause severe muscle damage called rhabdomyolysis. Diarrhea can occur, and it may be a sign of a serious infection in your colon.

Known Drug Interactions

moderate probenecid

7.2 Probenecid 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) ].

Mechanism: Probenecid blocks the kidneys from removing meropenem, which makes the level of the antibiotic in your blood go up.

What to do: You should not take these two medications together.

( 7.4 , 12.3 ) 7.1 Valproic 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. 7.2 Probenecid Probenecid competes with meropenem for active tubular secretion, resulting in increased plasma concentrations of meropenem.

Mechanism: Meropenem can significantly lower the amount of seizure medication in your blood, which increases the risk of having a seizure.

What to do: Your doctor may need to monitor your blood levels of seizure medicine or choose a different antibiotic to keep your seizures under control.

What the FDA Data Shows for meropenem/vaborbactam

The FDA label for meropenem/vaborbactam (sold under brand names such as Vabomere) classifies it as a prescription-only medication in the Carbapenem / Beta-Lactamase Inhibitor class. Vabomere treats complicated urinary tract infections (cUTIs) in adults. Official labeling lists 3 commonly reported side effects, including Headache, Irritation, swelling, or pain at the IV site, Diarrhea.

Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. For this drug, FAERS contains 18,241 voluntary reports. The database also lists 2 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated moderate severity. Acquisition-cost data is surveyed weekly by CMS and updated as manufacturers report changes.

Report counts do not establish causation — a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information further shape supply and switching decisions.
