What is Kefzol?
Kefzol is a cephalosporin (SEF a low spor in) antibiotic. It works by fighting bacteria in your body.
Kefzol is used to treat many kinds of bacterial infections, including severe or life-threatening forms. This medicine is also used to help prevent infection in people having certain types of surgery.
Kefzol may also be used for purposes not listed in this medication guide.
Before taking this medicine
You should not use Kefzol if you have ever had a severe allergic reaction to Kefzol or any other cephalosporin antibiotic, such as:
cefdinir (Omnicef), cefditoren (Spectracef);
cephalexin (Keflex), cephradine (Velosef).
To make sure Kefzol is safe for you, tell your doctor if you have:
a stomach or intestinal disorder such as colitis; or
if you are allergic to any type of penicillin.
Kefzol is not expected to harm an unborn baby. Tell your doctor if you are pregnant.
Cefazolin can pass into breast milk, but effects on the nursing baby are not known. Tell your doctor if you are breast-feeding.
How is Kefzol given?
Kefzol is injected into a vein through an IV.
A healthcare provider will give you this injection when Kefzol is used to prevent infection from surgery.
You may be shown how to use an IV at home to treat an infection. 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.
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Kefzol may need to be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.
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. Kefzol will not treat a viral infection such as the flu or a common cold.
This medicine can cause unusual results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using Kefzol.
Store unmixed Kefzol at room temperature, away from moisture, heat, and light.
After mixing Kefzol with a diluent, store the mixture in the refrigerator. Do not freeze.
Take the mixture out of the refrigerator and allow it to reach room temperature before injecting your dose. Mixed medicine must be used within a certain number of days once it reaches room temperature. Carefully follow all mixing and storage instructions for this medicine.
Do not use the medicine if it has changed colors or has particles in it. Call your pharmacist for new medication.
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.
