1. What is Biotaxym and what is it used for

Biotaxym contains a third-generation cephalosporin antibiotic - cefotaxime.
The medicine, after dissolution and proper dilution, is administered intramuscularly or intravenously
(in injection or infusion).
Cefotaxime is used:

• to treat severe infections caused by susceptible bacteria:
• lower respiratory tract infections, including pneumonia;
• urinary tract infections;
• infections in the pelvic area;
• septicemia;
• skin and soft tissue infections;
• intra-abdominal infections, including peritonitis;
• bone and joint infections;
• central nervous system infections, including meningitis;
• to prevent postoperative infections.

2. Important information before using Biotaxym

When not to use Biotaxym:

• if the patient is allergic to cefotaxime or other cephalosporins;
• if the patient is taking penicillins, due to the possibility of cross-reaction (see section: "Biotaxym and other medicines");
• if the patient has ever experienced a severe skin rash or exfoliation after taking cefotaxime or other cephalosporins;
• with lidocaine:
• in patients allergic to lidocaine or other amide local anesthetics;
• intravenously;
• in infants under 30 months of age;
• in patients with severe heart failure or heart block (without a pacemaker).

Warnings and precautions

Before starting treatment with Biotaxym, you should discuss it with your doctor or nurse.

• If the patient has an allergy, especially to cephalosporins and penicillins (and other beta-lactam antibiotics); you should be particularly careful, as people allergic to penicillins may also be allergic to cephalosporins (so-called cross-allergy). There is a risk of a severe allergic reaction. If an allergic reaction occurs, cefotaxime should be discontinued and, if necessary, appropriate treatment should be administered. In the treatment of severe reactions, the use of adrenaline and other anti-shock medications (circulatory supportive medications, corticosteroids, and antihistamines) may be necessary.
• Severe skin reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug rash with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP), have been reported with the use of cefotaxime. You should discontinue cefotaxime and immediately consult a doctor if any of the symptoms associated with these severe skin reactions occur, as described in section 4.
• If the patient has kidney problems, the doctor may order monitoring and, if necessary, reduce the dose of the medicine.
• If the patient experiences neurological symptoms such as changes in consciousness, abnormal movements, and seizures, they should consult a doctor before continuing treatment.
• If cefotaxime is used for a long time, as with other antibiotics, initially susceptible strains may become resistant, and an increase in bacteria from the Enterococcus spp. family may occur. The doctor may then recommend an antibiogram.
• If the patient experiences diarrhea associated with the use of the medicine, they should consult a doctor, who will recommend appropriate action. Rarely, during or after antibiotic treatment, pseudomembranous colitis may occur, characterized by diarrhea. The inflammation can be mild or severe. Mild cases usually resolve after discontinuation of the medicine. In more severe cases, the doctor may recommend taking metronidazole or vancomycin. You should not take medications that slow down bowel movements or have a constipating effect.
• If the patient has a history of colitis, especially colitis of the colon.
• If the patient is taking the medicine for more than 7 days, the doctor may recommend monitoring the white blood cell count and liver function.

Children

Children under 2 months of age should be given the medicine only intravenously.

Biotaxym and other medicines

You should tell your doctor about all medicines you are currently taking or have recently taken,
as well as any medicines you plan to take.
You should be careful when taking cefotaxime and:

• bacteriostatic agents (e.g., tetracycline, erythromycin, chloramphenicol, sulfonamides) - may weaken the antibacterial effect of cefotaxime;
• aminoglycoside antibiotics (e.g., streptomycin) and potent diuretics (e.g., furosemide) - may increase the harmful effect on kidney function;
• probenecid - increases the concentration of cefotaxime in the serum and prolongs its action.

Effect on laboratory test results
Taking cefotaxime may cause:

• false-positive results of glucose reduction tests in urine;
• false-positive Coombs test result.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, you should consult a doctor or pharmacist before taking this medicine.
Pregnancy
The safety of cefotaxime in pregnant women has not been established. Therefore, cefotaxime should not be used during pregnancy unless the expected benefits outweigh the risks.
Breastfeeding
Cefotaxime passes into breast milk. It cannot be excluded that it may affect the physiological intestinal flora of breastfed infants, leading to diarrhea, colonization of yeast-like fungi. A hypersensitivity reaction may also occur in the newborn. You should discuss with your doctor whether to stop breastfeeding or discontinue treatment, considering the benefit of breastfeeding for the child and the benefit of treatment for the mother.

Driving and using machines

There is no evidence that cefotaxime directly impairs the ability to drive vehicles and operate machines. High doses of cefotaxime, especially in patients with kidney failure, may cause changes in consciousness, movement disorders, and seizures. In such cases, you should not drive vehicles or operate machines.

Biotaxym contains sodium

The medicine contains 48 mg of sodium (the main component of common salt) per gram. This corresponds to 2.4% of the maximum recommended daily intake of sodium in the diet for adults.
This should be taken into account in patients with reduced kidney function and in patients controlling their sodium intake.
Preparation of the medicine for administration - see the section: "Information intended exclusively for healthcare professionals" at the end of the leaflet. When calculating the total sodium content in the prepared solution, you should take into account the sodium from the diluent. To obtain accurate information about the sodium content in the solution used to dilute the medicine, you should read the patient information leaflet of the diluent used.

3. How to use Biotaxym

This medicine should always be used in accordance with the doctor's recommendations. If you have any doubts, you should consult a doctor.
Dosage and method of administration are determined by the doctor, depending on the severity and type of infection, age, body weight, and kidney function of the patient.
Detailed dosing and administration instructions are provided at the end of the leaflet, in the section "Information intended exclusively for healthcare professionals".

Using a higher dose of Biotaxym than recommended

If you suspect that you have received too high a dose of Biotaxym, you should inform your doctor. Overdose may occur, especially in patients with kidney failure. Seizures, tremors, and coma may occur. In such cases, you should discontinue the medicine and receive appropriate treatment. Hemodialysis removes the medicine from the body.

Missing a dose of Biotaxym

If you suspect that a dose of Biotaxym has been missed, you should tell your doctor as soon as possible.

Information intended exclusively for healthcare professionals

BIOTAXYM, 1 g, powder for solution for injection or infusion

BIOTAXYM, 2 g, powder for solution for injection or infusion

Cefotaximum

Dosage

Adults and children over 12 years of age

For mild to moderate infections, 1 g is administered every 12 hours.
In severe infections, the daily dose can be increased to 12 g in 3 or 4 divided doses.
Daily doses up to 6 g should be divided into at least two doses, administered every 12 hours. Higher daily doses should be divided into at least 3 to 4 doses, administered every 8 or 6 hours.
Dosing guidelines are provided in the table below:

Infants and children under 12 years of age

In infants and children under 12 years of age, 50 mg to 150 mg/kg body weight per day of cefotaxime is administered in 2 or 4 divided doses.
In very severe infections, especially life-threatening ones, it may be necessary to increase the daily dose of cefotaxime to 200 mg/kg body weight per day in divided doses.
Children under 2 months of age should be given the medicine only intravenously.

Preterm and full-term newborns

The dose should not exceed 50 mg/kg body weight per day of cefotaxime in 2 to 4 divided doses.
In severe, life-threatening infections, it may be necessary to increase the daily dose from 150 to 200 mg/kg body weight per day, in divided doses.
In such cases, the dosing recommended in the table below is suggested:

Gonorrhea

Uncomplicated gonorrhea: a single intramuscular injection of 1 g of cefotaxime. Before starting treatment with cefotaxime, appropriate tests should be performed to rule out concurrent syphilis.

Prophylaxis of postoperative infections

A single dose of 1 g of cefotaxime should be administered 30 to 90 minutes before the surgical procedure.
Depending on the risk of infection, the administration of the medicine may be continued after the procedure.

Dosage in patients with kidney failure

A reduction in the dose of the preparation is necessary only in cases of severe kidney failure
(creatinine clearance less than 5 ml/min, serum creatinine concentration 751 micromoles/l). After the initial, loading dose of 1 g, the daily dose should be reduced by half without changing the frequency of administration of the medicine, e.g., a dose of 1 g every 12 hours should be reduced to 500 mg every 12 hours, a dose of 1 g every 8 hours should be reduced to 500 mg every 8 hours, a dose of 2 g every 8 hours should be reduced to 1 g every 8 hours, etc.
In some patients, further modification of the dose may be necessary, depending on the course of the infection and the patient's general condition.

Method of administration

The medicine, after proper dilution, is administered intravenously in a 3-5 minute injection or intramuscularly - deeply into the upper, outer quadrant of the gluteus maximus muscle or the lateral thigh.
The medicine can be administered in intravenous infusion.

Method of puncturing the vial

Puncture the stopper with a needle and inject the recommended volume of solvent into the vial. To puncture the stopper, a needle with a diameter not greater than 0,8 mm (21 G in the Gauge [G] scale) should be used. The needle should be inserted into the centrally marked field at a 90° angle, as shown in the scheme below:

After adding the solvent to the vial, it should be shaken until the preparation dissolves, after 1-2 minutes the solution is clear. Before administering the medicine, you should check if the solution is clear and does not contain insoluble particles. The solution of the medicine may be colorless or light yellow.

Preparation of solutions for injection and infusion

Intramuscular injection

The medicine should be administered deeply intramuscularly after dissolution in an appropriate amount of water for injection or 1% lidocaine solution. Do not administer intravenously a solution of the medicine with lidocaine.
Intravenous injection(from 3 to 5 minutes)
The contents of the vial are dissolved in water for injection in a volume dependent on the dose, as shown in the table above.
Intravenous infusion(from 20 to 60 minutes)
To prepare solutions for intravenous infusion, the powder is dissolved in water for injection (as for intravenous injections). The resulting solution should then be diluted with one of the following solutions:

• 0.9% sodium chloride solution,
• 5% glucose solution,
• 5% glucose solution with 0.45% sodium chloride solution,
• 5% glucose solution with 0.2% sodium chloride solution,
• Ringer's lactate solution,
• sodium lactate solution for injection (M/6). It is not recommended to use infusion solutions containing sodium bicarbonate, as cefotaxime is unstable in these solutions.

Cefotaxime and aminoglycosides should not be mixed in the same syringe or infusion solution.
If concurrent administration is necessary, these medicines should be injected at different sites.
