How is Zerbaxa given?
This medicine is usually given for 4 to 14 days, depending on the type of infection being treated. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
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. Zerbaxa will not treat a viral infection such as the common cold or flu.
Zerbaxa is injected into a vein through an IV. You may be shown how to use an IV at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine.
Zerbaxa is a powder medicine that must be mixed with a liquid (diluent) before using it. You will then need to dilute this mixture into a solution with another liquid in an IV bag. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.
Each single-use vial (bottle) of this medicine is for one use only. Throw away after one use, even if there is still some medicine left in it after preparing your dose.
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.
Store the dry powder medicine in a refrigerator. Do not freeze.
After you mix the powder and diluent, you may store this mixture at room temperature for up to 1 hour before further diluting it.
Medicine mixed in an IV bag must be used within 24 hours if you keep it at room temperature.
Mixed medication in an IV bag can also be stored in the refrigerator for up to 7 days. Do not freeze. Throw away any unused mixture that has not been used within that time.
Do not use the diluted solution if it has changed colors or has particles in it. Call your pharmacist for new medication.
