1. What is Cefotaxima Normon and what is it used for

This medicine belongs to a group of medicines called cephalosporins, used to combat bacteria.

Cefotaxima is indicated in severe, acute, and chronic bacterial infections caused by pathogens sensitive to cefotaxima:

• Respiratory infections.
• Otorhinolaryngological infections.
• Renal and urinary tract infections.
• Skin and soft tissue infections.
• Bone and joint infections.
• Gynecological infections, including gonorrhea.
• Abdominal infections (including peritonitis).
• Meningitis.
• Blood poisoning (sepsis).
• Heart inflammation (endocarditis).
• Lyme disease (especially in stages II and III) (infection mainly caused by tick bites).

Additionally, for the prevention of infections after surgical interventions in patients with a higher risk of infections.

2. What you need to know before you use Cefotaxima Normon

Do not use Cefotaxima Normon

• If you are allergic to cefotaxima, other cephalosporins, or any of the other components of this medicine (listed in section 6).
• If you have had a previous acute or severe hypersensitivity reaction to penicillin or other beta-lactam antibiotics. Penicillin and cephalosporins can cause cross-reactions.
• If you have ever suffered from a severe skin rash, peeling, or blisters in the mouth after taking cefotaxima or other cephalosporins.

Do not take Cefotaxima Normon or inform your doctor if any of these apply to you.

The use of cefotaxima mixed with lidocaine for intramuscular injection is not indicated in children under 30 months of age. The package leaflet for the product containing lidocaine must be taken into account.

Warnings and Precautions

Consult your doctor or pharmacist before starting to use cefotaxima:

• If you are allergic to penicillin or other beta-lactam antibiotics in any form (for contraindications due to known hypersensitivity reactions, see above in the section "Do not use Cefotaxima Normon").
• If you have an allergic reaction (e.g., hay fever, bronchial asthma, hives) or if you are known to have one. In this case, you have a higher risk of more severe hypersensitivity reactions (which can be fatal in exceptional cases). If you experience a feeling of chest tightness, or feel dizzy, sick, or weak, these may be signs of a hypersensitivity reaction (see section 4).
• If a hypersensitivity reaction occurs, treatment should be discontinued.
• If you experience severe or persistent diarrhea during treatment or for several weeks after its completion. Inform your doctor immediately, as diarrhea in its most severe form (called pseudomembranous colitis) could be life-threatening and requires treatment. Do not take any medication that limits intestinal activity.
• If you know you have kidney failure. Inform your doctor in this case; if necessary, they may adjust your dose. It is necessary to monitor your kidney function.
• If you are receiving concomitant or subsequent treatment with aminoglycosides (other antibiotics), probenecid (for gout), or other medications that can cause kidney damage. A doctor should monitor your kidney function, as these substances can increase the harmful effects on the kidneys and caution is needed.
• If you experience movement disorders, have seizures, or confusion, or have altered consciousness. These may be signs of what is called encephalopathy. There is a risk of these adverse effects when high doses are administered, in case of overdose, or if you have kidney failure. If these reactions occur, consult your doctor immediately.
• If your treatment lasts more than 7 to 10 days. In this case, control blood tests should be performed because changes in the blood may appear (see also section 4).
• If you have signs of a new infection (e.g., fungal infection of the mucous membranes with redness and a white surface). The use of antibiotics can increase the amount of pathogens that are not sensitive to the used medicine. Be vigilant for signs of a new infection and inform your doctor if necessary.

Be especially careful with Cefotaxima Normon

• Severe skin reactions, such as Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP), have been reported with cefotaxima treatment. Stop taking cefotaxima and seek immediate medical attention if you observe any of the symptoms described in section 4 related to these severe skin reactions.

Other medicines and Cefotaxima Normon

Inform your doctor or pharmacist if you are using, have recently used, or might use any other medicine.

Other antibiotics

The concomitant use of some antibiotics may reduce the effect of cefotaxima. Inform your doctor if you are taking or have recently taken other antibiotics.

Diuretics and potentially kidney-damaging medications

When cefotaxima is used in conjunction with medications that can have a harmful effect on the kidneys, such as aminoglycosides (other antibiotics) or medications with a high capacity to cause dehydration (diuretics, such as furosemide), it can increase the harmful effect on the kidneys of these medications. If administered concomitantly, kidney function should be monitored (see section 2 "Warnings and Precautions").

Probenecid

The simultaneous administration of probenecid leads to an increase in the concentration of cefotaxima in the serum and, therefore, to the extension of its effect, because probenecid limits the elimination of cefotaxima by the kidneys. Inform your doctor if you are taking probenecid, especially if you have kidney failure, so that, if necessary, they can adjust your dose.

Pregnancy, breastfeeding, and fertility

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

Pregnancy

There are insufficient data on the use of cefotaxima in pregnant women. Animal experiments did not show signs of teratogenic properties of cefotaxima.

However, cefotaxima should only be used during pregnancy, especially in the first trimester, after a strict evaluation of the risks and benefits of treatment by a specialist.

Breastfeeding

Cefotaxima is excreted in breast milk only in small amounts. If you receive cefotaxima during breastfeeding, it may cause changes in the intestinal flora with diarrhea, fungal growth, and may also cause sensitization. The doctor will decide whether it is necessary to interrupt breastfeeding or discontinue treatment with cefotaxima, considering the benefit of breastfeeding for the child and the benefit of treatment for the mother.

Driving and using machines

According to previous experience, cefotaxima in low and medium doses does not have any effect on concentration or reaction ability.

If you experience adverse effects such as dizziness or encephalopathy, which can be associated with seizures, confusion, altered consciousness, and movement disorders, do not drive or use machines.

Cefotaxima Normon contains sodium

This medicine contains 50.6 mg (2.20 mmol) of sodium (the main component of table salt/cooking salt) per dose. This is equivalent to 2.53% of the maximum recommended daily sodium intake for an adult.

3. How to use Cefotaxima Normon

Follow the instructions for administration of this medicine exactly as indicated by your doctor. If in doubt, consult your doctor or pharmacist again.

The dose, method of administration, and time intervals between injections depend on the dose, sensitivity of the pathogen, severity of the infection, and the patient's condition.

Unless the doctor considers otherwise, the recommended dose is:

Adults and children over 12 years:the usual dosage is 1 g of cefotaxima every 12 hours. In severe cases, the daily dose can be increased up to 12 g. Daily doses up to 6 g can be divided into at least two fractionated doses administered at 12-hour intervals. Higher daily doses should be divided into at least 3-4 fractionated doses with administration intervals of 6 or 8 hours.

The following table can be considered a guideline for administration:

For the treatment of gonorrheain adults, a single dose of 0.5 g of cefotaxima should be administered intramuscularly. In less sensitive pathogens, a dose increase may be necessary. Before starting treatment, check for the presence of syphilis.

For perioperative prophylaxis of infections, administration of 1-2 g of cefotaxima 30-60 minutes before surgery is recommended. Less sensitive pathogens may require a higher dose. Before starting treatment, check for the presence of syphilis.

For Lyme disease, the daily dose is 6 g of cefotaxima (for 14 to 21 days). In most cases, the daily dose is divided into 3 fractionated doses (2 g of cefotaxima 3 times a day), but in some cases, it has been administered in 2 fractionated doses (3 g of cefotaxima 2 times a day). The dosage recommendations are not based on comparative clinical trials but on observations of individual patients.

Combined treatment

In severe infections that pose a life-threatening risk, combined treatment with cefotaxima and aminoglycosides without an antibiogram is indicated. When combined with aminoglycosides, kidney function should be monitored.

In cases of Pseudomonas aeruginosainfection, combined treatment with other antibiotics effective against Pseudomonasmay also be indicated.

For the prophylaxis of infections in patients with a weakened immune system, combined treatment with other appropriate antibiotics may also be indicated.

Infants and children up to 12 yearsreceive 50 to 100 mg of cefotaxima (up to 150 mg) per kilogram of body weight daily, depending on the severity of the infection. The daily dose will be divided into 2 or more identical fractionated doses, which will be administered at intervals of 12 (to 6) hours. In individual cases, especially in life-threatening situations, the daily dose can be increased to 200 mg of cefotaxima per kilogram of body weight.

In premature infants, it should be taken into account that kidney function is not yet fully developed and the dose should not exceed 50 mg of cefotaxima per kilogram of body weight per day.

In patients with severe kidney failure(creatinine clearance less than 10 ml/minute), after the initial normal dose (the first dose at the start of treatment), the maintenance dose can be reduced to half of the normal dose, maintaining the administration interval.

Patients on hemodialysis receive 1 to 2 g of cefotaxima daily, depending on the severity of the infection. On the day of hemodialysis, cefotaxima should be administered after dialysis.

Patients on peritoneal dialysis receive 1 to 2 g of cefotaxima daily, depending on the severity of the infection. Cefotaxima is not eliminated by peritoneal dialysis.

Cefotaxima Normon 1 g is administered intravenously (in a vein), but it can also be administered intramuscularly.

Elderly patients

In elderly patients, kidney function should be carefully monitored and, if necessary, the dose should be adjusted.

If you use more Cefotaxima Normon than you should

Beta-lactam antibiotics, including cefotaxima, can cause encephalopathies, which are accompanied by central nervous system excitement, myoclonus, seizures, confusion, altered consciousness, and movement disorders. There is a risk of these adverse effects when high doses are used, in case of overdose, or in patients with impaired kidney function or those suffering from epilepsy or meningitis.

If cefotaxima is injected through a central venous catheter (CVC) too quickly (in less than 1 minute), it can cause a severe cardiac arrhythmia.

If you think you have received too much cefotaxima, talk to your doctor or medical staff immediately.

If you forget to use Cefotaxima Normon

Your doctor or nurse will have instructions on when to administer the medicine, so it is unlikely that you will not receive the medicine according to the instructions. If you think you have missed a dose, talk to your doctor or nurse.

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

4. Possible Adverse Effects
