How is cefoxitin given?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Mefoxin is injected into a vein through an IV. You may be shown how to use an IV at home. 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.
Mefoxin is a powder medicine that must 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. Mefoxin will not treat a viral infection such as the flu or a common cold.
Mefoxin can cause unusual results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using this medicine.
Store the dry powder medicine in a refrigerator, or at cool room temperature (between 36 and 77 degrees F).
After mixing Mefoxin powder with a diluent, store the mixture in a refrigerator and use within 1 week.
Mixed medicine must be used within 6 hours if you keep it at room temperature.
The temperature and length of time you can store mixed medicine will depend on the type and amount of diluent used in the mixture. 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.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
