How should I use ceftizoxime injection (Cefizox)?

Ceftizoxime is given as an injection into a muscle or a vein. Injection into a vein must be given slowly through an IV infusion, and can take up to 30 minutes to complete.

Your doctor, nurse, or other healthcare provider will give you this injection. You may be given instructions on how to use your injections at home. Do not use this medicine at home if you do not fully understand how to give the injection and properly dispose of needles, syringes, and other items used in giving the medicine.

Use the medication exactly as it was prescribed for you. Do not use the medication in larger amounts, or use it for longer than recommended by your doctor. Follow the instructions on your prescription label.

Use this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Ceftizoxime will not treat a viral infection such as the common cold or flu.

To use the medicine, thaw it in a refrigerator or at room temperature. Do not warm in a microwave or boiling water. Keep thawed medicine in the refrigerator and use it within 28 days after thawing it. Do not refreeze thawed medicine.
