How is Doribax given?

Use Doribax exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Doribax 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.

Doribax is usually given for 5 days to 2 weeks, depending on the condition being treated. You may be switched to an oral (pill form) antibiotic after the first few days of receiving doripenem by injection.

Doribax is a powder that must be mixed with a liquid (diluent). You will need to place the doripenem and diluent mixture in an IV bag of infusion solution before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medicine. Ask your pharmacist if you have questions.

Use this medication 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. Doribax will not treat a viral infection such as the common cold or flu.

After mixing the doripenem and diluent mixture with an IV infusion solution, you may store it at room temperature or in a refrigerator. Do not freeze.

At room temperature: You may store the mixture for up to 4 hours if your infusion solution is 5% dextrose, or up to 12 hours if your infusion solution is normal saline.

In a refrigerator: You may store the mixture for up to 24 hours if your infusion solution is 5% dextrose, or up to 72 hours if your infusion solution is normal saline.

Doribax does not contain a preservative. Throw away any Doribax mixture not used within the correct number of hours based on your infusion solution and storage method.

What happens if I overdose?

What should I avoid?

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop using Doribax and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
