Meropenem and vaborbactam are antibiotics that fight bacteria.

Meropenem and vaborbactam is a combination medicine used to treat serious urinary tract infections in adults.

Meropenem and vaborbactam may also be used for purposes not listed in this medication guide.

Before you receive meropenem and vaborbactam, tell your doctor if you have a history of allergies to any antibiotic medications.

Follow all directions on your prescription label. Do not use meropenem and vaborbactam in larger or smaller amounts or for longer than recommended.

Meropenem and vaborbactam is injected into a vein through an IV. You may be shown how to use an IV at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of needles, IV tubing, and other items used.

Meropenem and vaborbactam is usually given every 8 to 12 hours for up to 14 days. This medicine must be given slowly, and the infusion can take about 3 hours to complete.

Meropenem and vaborbactam is a powder medicine that must be mixed with a liquid (diluent), and then further diluted before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.

The diluted mixture must be used within 4 hours if you keep it at room temperature. If you store the IV bag in a refrigerator, use it within 22 hours. Do not freeze.

Each single-use vial (bottle) of meropenem and vaborbactam powder is for one use only. Throw it away after one use, even if there is still medicine left inside.

Do not mix other injectable medications in the same IV bag or tubing used to given your meropenem and vaborbactam injection.

Throw away any unused medicine left in the IV bag after your infusion. Do not not save it for later use.

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Meropenem and vaborbactam will not treat a viral infection such as the common cold or flu.

Your kidney function may need to be checked while you are using this medicine.

Store unmixed powder at room temperature away from moisture and heat.

Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
