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

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

Cefotaxime is indicated for severe, acute and chronic bacterial infections caused by pathogens sensitive to cefotaxime:

• Respiratory tract 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).
• Inflammation of the heart (endocarditis).
• Lyme disease (especially in stages II and III) (infection caused mainly by tick bites).

In addition, for the prevention of infections following surgical procedures in patients at higher risk of infections.

2. What you need to know before using Cefotaxime Normon

Do not use Cefotaxime Normon

• If you are allergic to cefotaxime, to other cephalosporins, or to any of the other components of this medicine (listed in section 6).
• If you have previously experienced an acute or severe hypersensitivity reaction to penicillin or to other beta-lactam antibiotics. Penicillins and cephalosporins may cause cross-reactions.
• If you have ever had a severe skin rash, peeling skin, blisters, or mouth sores after taking cefotaxime or other cephalosporins.

Do not take Cefotaxime Normon or inform your doctor if any of the above apply to you.

The use of cefotaxime mixed with lidocaine for intramuscular injection is not indicated in children under 30 months of age. The product leaflet containing lidocaine should be consulted for preparation instructions.

Warnings and precautions

Talk to your doctor or pharmacist before using cefotaxime:

• If you are allergic to penicillin or to other beta-lactam antibiotics in any form (for contraindications due to known hypersensitivity reactions, see above in the section "Do not use Cefotaxime Normon").
• If you have an allergic reaction (e.g., hay fever, bronchial asthma, hives) or if you have a history of such conditions. In this case, you have a higher risk of more severe (and in rare cases, fatal) hypersensitivity reactions. If you experience chest tightness, dizziness, nausea, or weakness, these may be signs of a hypersensitivity reaction (see section 4).
• If a hypersensitivity reaction occurs, treatment must be discontinued.
• If you develop severe or persistent diarrhea during treatment or for several weeks after stopping treatment. Inform your doctor immediately, as diarrhea in its most severe form (called pseudomembranous colitis) can be life-threatening and requires treatment. Do not take any medication that reduces intestinal motility.
• If you know you have kidney impairment. Inform your doctor; the dose may need to be adjusted. Your kidney function should be monitored.
• If you are receiving concomitant or subsequent treatment with aminoglycosides (other antibiotics), probenecid (for gout), or other medicines that may cause kidney damage. Your kidney function should be monitored by a doctor, as these substances may increase kidney-related adverse effects and caution is required.
• If you experience movement disorders, seizures, confusion, or altered consciousness. These may be signs of what is called encephalopathy. The risk of these adverse effects increases with high doses, overdose, or in case of renal impairment. If such reactions occur, consult your doctor immediately.
• If your treatment lasts longer than 7 to 10 days. In this case, blood tests should be performed to monitor for possible blood changes (see also section 4).
• If you show signs of a new infection (e.g., fungal infection of mucous membranes with redness and a white coating). Antibiotic use may increase the presence of pathogens not sensitive to the drug. Watch for signs of new infections and inform your doctor if necessary.

Take special care with Cefotaxime 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 cefotaxime treatment. Stop taking cefotaxime and seek immediate medical attention if you notice any of the symptoms described in section 4 related to these serious skin reactions.

Other medicines and Cefotaxime Normon

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Other antibiotics

Concomitant use of certain antibiotics may reduce the effectiveness of cefotaxime. Inform your doctor if you are taking or have recently taken other antibiotics.

Diuretics and medicines potentially harmful to the kidneys

When cefotaxime is used together with medicines that may have a harmful effect on the kidneys, such as aminoglycosides (other antibiotics) or medicines that may cause significant dehydration (diuretics, such as furosemide), the kidney-related adverse effects of these medicines may increase. If administered together, kidney function should be monitored (see section 2, "Warnings and precautions").

Probenecid

Concomitant administration of probenecid leads to increased serum concentrations of cefotaxime and thus prolongs its effect, as probenecid reduces the renal elimination of cefotaxime. Inform your doctor if you are taking probenecid, especially if you have renal impairment, so that the dose may be adjusted if necessary.

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 cefotaxime in pregnant women. Animal studies did not show signs of teratogenic properties of cefotaxime.

Nevertheless, cefotaxime should only be used during pregnancy, especially in the first trimester, after a strict assessment of the risks and benefits of treatment by a specialist.

Breastfeeding

Cefotaxime is excreted in breast milk only in small amounts. If you receive cefotaxime during breastfeeding, it may cause disturbances in intestinal flora resulting in diarrhea, fungal overgrowth, and may also lead to sensitization. The doctor will decide whether to interrupt breastfeeding or discontinue treatment with cefotaxime, taking into account the benefits of breastfeeding for the child and the benefits of treatment for the mother.

Driving and use of machines

Based on previous experience, cefotaxime at low and medium doses has no effect on concentration or reaction ability.

However, if you experience adverse effects such as dizziness or encephalopathy, which may be associated with seizures, confusion, altered consciousness, or movement disorders, you should not drive or operate machinery.

Cefotaxime Normon contains sodium

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

3. How to use Cefotaxime Normon

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

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

Unless otherwise determined by the physician, the recommended dose is:

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

The following table may be considered a dosage guideline:

For the treatment of gonorrhoea in adults, a single dose of 0.5 g of cefotaxime should be administered intramuscularly. In less sensitive pathogens, a higher dose may be required. Before starting treatment, check for the presence of syphilis.

For perioperative prophylaxis of infections, administration of 1–2 g of cefotaxime 30–60 minutes before surgery is recommended. Higher doses may be needed for less sensitive pathogenic microorganisms. Before starting treatment, check for the presence of syphilis.

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

Combination therapy

In severe, life-threatening infections, combination therapy with cefotaxime and aminoglycosides is indicated, even without an antibiogram. When combined with aminoglycosides, renal function must be monitored.

In infections caused by Pseudomonas aeruginosa, combination therapy with other antibiotics effective against Pseudomonas may also be indicated.

For infection prophylaxis in patients with weakened immune systems, combination therapy with other appropriate antibiotics may also be indicated.

Infants and children up to 12 years of age receive 50 to 100 mg of cefotaxime (up to 150 mg) per kilogram of body weight daily, depending on the severity of the infection. The daily dose should be divided into 2 or more equal divided doses administered at intervals of 12 (to 6) hours. In individual cases, especially in life-threatening situations, the daily dose may be increased to 200 mg of cefotaxime per kilogram of body weight.

In premature infants, it must be considered that renal function is not yet fully developed, and the dose should not exceed 50 mg of cefotaxime per kilogram of body weight per day.

In patients with severe renal impairment (creatinine clearance less than 10 ml/min), after the normal initial dose (the first dose at the beginning of treatment), the maintenance dose can be reduced to half the normal dose, maintaining the same dosing interval.

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

Patients undergoing peritoneal dialysis receive 1 to 2 g of cefotaxime daily, depending on the severity of the infection. Cefotaxime is not removed by peritoneal dialysis.

Cefotaxime Normon 1 g is administered intravenously (into a vein), but may also be administered intramuscularly.

Elderly patients

In elderly patients, renal 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 cefotaxime, may cause so-called encephalopathies, accompanied by central nervous system excitation, myoclonus, seizures, confusion, impaired consciousness, and movement disorders. This risk exists with higher doses, in cases of overdose, and in patients with impaired renal function or those suffering from epilepsy or meningitis.

If cefotaxime is injected too rapidly through a central venous catheter (CVC) (in less than 1 minute), it may cause a serious cardiac arrhythmia.

If you think you have received too much cefotaxime, speak immediately with your doctor or medical staff.

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 the medicine will not be administered as directed. If you think a dose has been missed, speak with your doctor or nurse.

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

4. Possible adverse effects
