ADVICE/MEDICAL EDUCATION

What should you know about antibiotics?

Antibiotics are effective against infections caused by bacteria. They do not work against infections caused by viruses. Also, your doctor chose to prescribe this antibiotic for you because it suits your particular case and your current illness. Some bacteria have the ability to survive and reproduce despite the action of an antibiotic. This phenomenon is known as resistance: it inactivates certain antibiotic treatments.

Resistance is the result of abusive or inappropriate use of antibiotics.

You may promote the development of resistant bacteria and therefore delay your recovery or even inactivate this medicine, if you do not:

• take the dose prescribed for you,
• take it as often as prescribed,
• complete the whole course of treatment.

Therefore, to preserve the efficacy of this medication:

1. 1. Do not use an antibiotic unless it has been prescribed by your doctor.
2. 2. Take it exactly as prescribed.
3. 3. Do not reuse an antibiotic without a prescription, even if you think you are treating an illness that appears to be similar.
4. 4. Never give your antibiotic to another person, because it may not be appropriate for that person’s illness.
5. 5. Once your treatment is complete, return to your pharmacist any opened boxes so that they can be discarded correctly and appropriately.

The following information is intended for healthcare professionals only:

Special precautions for disposal and other handling

Cefoxitin may be reconstituted with 10 ml water for injections. Immediately after reconstitution, this Cefoxitin solution can be also added to 40 ml of the following solutions, frequently used in infusion(1g or 2g into 50 ml solution, corresponding to 20 to 40mg/ml):

• sodium chloride 0.9%,
• glucose 5% or 10%,
• mixed solution of glucose 5% and sodium chloride 0.9%,
• glucose 5% buffered with sodium bicarbonate 0.02%,
• glucose 5% supplemented with saline solution 0.2% or 0.45%,
• Ringer's Lactate solution,
• mixed solution of glucose 5% and Ringer Lactate,
• mixed solution of fructose 5% or 10% in water for injections,
• fructose 10% solution in saline solution,
• Sodium lactate solution at M/6.

This medicine may be given together with other antibiotics (intravenously with separate syringes or infusions). When this medicine is administered at the same time as another antibiotic, it is important that the antibiotics are not mixed in the same syringe or infusion.

Reconstitution

Renoxitin should be reconstituted with water for injections: 1 g is soluble in 2 ml. Although, Renoxitin is very soluble, for intravenous use it is preferable to add 10 ml of water for injections to the 1 g vial or to the 2 g vial. It should be shaken to dissolve and then withdraw the entire contents of the vial into a syringe.

Dilution

The reconstituted solution should be diluted with the solvents mentioned above in section 6.6: add around 40 ml of the solvent to the reconstituted solution in order to reach a total volume of 50 ml.

The product should be used immediately after reconstitution/dilution.

Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
