How is cefazolin given?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Cefazolin is injected into a vein.
This medicine must be given slowly over 30 minutes.
Ask your doctor or pharmacist if you don't understand how to use an injection.
Cefazolin may need to be mixed with a liquid (diluent) before using it. Prepare an injection only when you are ready to give it. Call your pharmacist if the medicine has changed colors or has particles in it.
Do not reuse a needle or syringe. Place them in a puncture-proof "sharps" container and dispose of it following state or local laws. Keep out of the reach of children and pets.
Keep using this medicine even if your symptoms quickly improve. Skipping doses could make your infection resistant to medication. Cefazolin will not treat a viral infection (flu or a common cold).
This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using cefazolin.
Store unmixed cefazolin at room temperature, away from moisture, heat, and light. Do not freeze.
Cefazolin mixed with a diluent can be stored at room temperature for up to 24 hours, or in a refrigerator for up to 7 days.
If cefazolin is frozen when you receive it, thaw the medicine at room temperature (do not use heat).
After thawing, you may store cefazolin at room temperature for up to 48 hours, or in a refrigerator for 30 days. Do not refreeze the medicine once it has been thawed.
Carefully follow all mixing and storage instructions for this medicine.
