• If you are on a low-sodium diet.

If you are to have blood or urine tests

If you are administered ceftriaxone for a prolonged period, you may need to have blood tests regularly.

Ceftriaxone may affect the results of blood glucose tests and a blood test called the Coombs test. If you are to have tests:

• Inform the person who takes the sample that you are being administered ceftriaxone.

If you are diabetic or need to control your blood glucose levels, do not use some blood glucose monitoring systems that may give incorrect results while you are being administered ceftriaxone. If you use these systems, check the instructions and consult your doctor, pharmacist, or nurse.

Alternative analysis methods should be used if necessary.

Children

Consult your doctor, pharmacist, or nurse before administering Medaxone to your child if:

• Recently administered in a vein a product containing calcium.

Use of Medaxone with other medications

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

Specifically, inform your doctor or pharmacist if you are taking any of the following medications:

• A group of antibiotics known as aminoglycosides.
• An antibiotic called chloramphenicol (used to treat infections, especially eye infections).

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or intend to become pregnant, consult your doctor or pharmacist before using this medication.

Your doctor will evaluate the benefits of ceftriaxone treatment for you and the risk it poses to your child.

Driving and operating machinery

Ceftriaxone may cause dizziness. If you feel dizzy, do not drive or operate tools or machinery.

Consult your doctor if you experience these symptoms.

Medaxone is usually administered by a doctor or a nurse.

It can be administered in the form of

• intravenous infusion (drip) or
• in a muscle.

The doctor, pharmacist, or nurse reconstitutes Medaxone and it should not be mixed or administered simultaneously with injections that contain calcium.

Recommended dose

Your doctor will decide on the correct dose of Medaxone for you. The dose will depend on the severity and type of infection, whether you are receiving other antibiotics, your weight and age, and whether your kidneys and liver are functioning properly.

The number of days or weeks that you will be administered Medaxone will depend on the type of infection you have.

Adults, elderly, and children 12 years of age or older with a body weight of 50 kilograms (kg) or more:

• 1 to 2g once a day depending on the severity and type of infection. If the infection is severe, your doctor will increase the dose (up to 4 g once a day). If the daily dose is greater than 2g, it may be administered once a day or divided into two doses.

Newborns, infants, and children between 15 days and 12 years of age with a body weight less than 50 kg:

• 50-80 mg of ceftriaxone per kg of the child's weight once a day depending on the severity and type of infection. If the infection is severe, your doctor will increasethe dose up to 100 mg per kg of body weight up to a maximum of 4 g once a day. If the daily dose is greater than 2g, it may be administered once a day or divided into two doses.
• Children weighing 50 kg or more should receive the usual adult dose.

Newborns (0-14 days)

• 20-50 mg of ceftriaxone per kg of the child's weight once a day depending on the severity and type of infection.
• The maximum daily dose should not exceed 50 mg per kg of the baby's weight.

Patients with liver and kidney problems

You may be administered a different dose than the usual one. Your doctor will decide how much Medaxone you need and will closely monitor you depending on the severity of the liver and kidney disease.

If you take more Medaxone than you should

If you accidentally receive a higher dose than prescribed, go to your doctor or the nearest hospital immediately.

If you forget to use Medaxone

If you forget a dose, you should take it as soon as possible. However, if it is almost time for your next dose, omit the missed dose. Do not administer a double dose (two injections at the same time) to compensate for the missed dose.

If you interrupt the treatment with Medaxone

Do not stop using ceftriaxone unless your doctor tells you to.

If you have any other questions about the use of this medication, ask your doctor, pharmacist, or nurse.

This information is intended solely for healthcare professionals:

See the product characteristics summary for the complete technical data sheet.

Administration form

Intramuscular injection

Medaxone can be administered by deep intramuscular injection. 2g of ceftriaxone should be dissolved in 7ml of lidocaine for injection at 1%.

Intramuscular injections should be administered deeply in the mass of a relatively large muscle and not more than 1g per site.

Since the solvent used is lidocaine, the resulting solution should never be administered intravenously.

Intravenous infusion

Medaxone can be administered by intravenous infusion for at least 30 minutes (preferred route).

2g of ceftriaxone should be dissolved in 40ml of one of the following calcium-free solutions.

Intravenous doses of 50 mg/kg or more in infants and children up to 12 years should be administered by infusion. In neonates, intravenous doses should be administered over 60 minutes to reduce the possible risk of bilirubin encephalopathy. The intramuscular route should be evaluated when the intravenous route is not possible or less appropriate for the patient. For doses greater than 2 g, the intravenous route should be used.

Ceftriaxone is contraindicated in neonates (≤ 28 days) if they require (or are expected to require) treatment with intravenous solutions containing calcium, for example, continuous infusions containing calcium such as total parenteral nutrition, due to the risk of ceftriaxone-calcium precipitation.

Do not use diluents containing calcium (e.g. Ringer's solution or Hartmann's solution) to reconstitute ceftriaxone vials or to dilute a reconstituted vial for intravenous administration because precipitation may occur. Ceftriaxone-calcium precipitation may also occur when ceftriaxone is mixed with solutions containing calcium in the same intravenous administration catheter. Therefore, ceftriaxone solutions and solutions containing calcium should not be mixed or administered simultaneously.

For prophylaxis of surgical site infections, ceftriaxone should be administered 30-90 minutes before the intervention.

Instructions for use

It is recommended to use freshly prepared solutions. These maintain potency for at least 6 hours at 25°C or 24 hours at 2-8°C.

Intramuscular injection:

2 g of ceftriaxone should be dissolved in 7 ml of lidocaine injection at 1%.

The solution can be administered by deep intramuscular injection. Doses greater than 1 g should be fractionated and injected in more than one site.

Ceftriaxone should not be mixed in the same syringe with any other drug except a 1% lidocaine injection (only for intramuscular injection).

Solutions in lidocaine should not be administered intravenously.

Ceftriaxone is compatible with various intravenous infusion liquids of common use, such as dextrose for injection BP at 5% or 10%, sodium chloride for injection BP, sodium chloride (0.45%), dextrose for injection (2.5%) BP, dextran at 6% in dextrose for injection BP at 5%, and hydroxyethyl starch at 6%.

The infusion should be administered for at least 30 minutes.

Concentrations for intravenous infusion: 50 mg/ml

Disposal of unused medication and all materials that have come into contact with it will be carried out in accordance with local regulations.

Incompatibilities:

Based on bibliographic publications, ceftriaxone is not compatible with amsacrine, vancomycin, fluconazole, aminoglycosides, and labetalol.

Solutions containing ceftriaxone should not be mixed or added to other agents except those mentioned in the "Instructions for use". In particular, diluents containing calcium (such as Ringer's solution or Hartmann's solution) should not be used to reconstitute ceftriaxone vials or to dilute a reconstituted vial for intravenous administration because precipitation may occur. Ceftriaxone should not be mixed or administered simultaneously with solutions containing calcium, including total parenteral nutrition.
