Additionally, changes in blood coagulation may occur in patients with diseases that may cause or worsen bleeding, such as hemophilia or stomach or intestinal ulcers. In these cases, your blood coagulation will be monitored.
This medicine should not be injected into the area near the spinal cord (intrathecally), as cases of central nervous system toxicity (including seizures) have been reported.
Prolonged use of cefazoline may lead to superinfections. Your doctor will monitor you closely for this and treat it if necessary.
Children

Use of Cefazoline with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This also applies to over-the-counter medicines and herbal medicines, as Cefazoline Normon may affect how other medicines work. Additionally, other medicines may affect how Cefazoline Normon works.

- Aminoglycosides or other antibiotics (used to treat infections).
- Probenecid (used to treat gout).
- Vitamin K.

3. How to use Cefazoline Normon
Follow the instructions for administration of this medicine exactly as indicated by your doctor or pharmacist. If you are unsure, consult your doctor or pharmacist again.
Cefazoline should only be administered by properly qualified personnel (doctors or other healthcare professionals).
Remember to use your medicine.
Your doctor will indicate the duration of your treatment with Cefazoline Normon.
The selected dose should be established according to the infection, the patient's condition, and the sensitivity of the causative agent to cefazoline.
The recommended dose is:
Adults and children over 12 years:for mild infections, 500 mg every 8 hours (total daily dose 1.5g); for moderate to severe infections, 500 mg to 1g every 6 or 8 hours (total daily dose 3g-4g); for severe infections, 1 to 1.5g every 6 hours (total daily dose 4g-6g).
Children (under 12 years and over 1 month):a total daily dose of 25 to 50 mg per kg of body weight, divided into three or four equal doses, is effective in most mild to moderate infections. The total daily dose should not exceed 100 mg/kg, even in cases of severe infections.
Prevention of surgical infections / postoperative infections in adultsTo prevent postoperative infection in surgery, the recommended doses are as follows:
- 1-2 g intramuscularly administered 1/2 to 1 hour before starting surgery.
- for prolonged surgical procedures (e.g., 2 hours or more) 500mg to 1 g intramuscularly during surgery (the dosage will be adjusted depending on the duration of the procedure).
- 500 mg to 1 g intramuscularly every 6 to 8 hours during the 24 hours postoperative.
Prevention of surgical infections / postoperative infections in children
- 25-30 mg/kg for children up to a maximum of 50 mg/kg (the maximum dose should not exceed 2 g)
It is essential that the preoperative dose is administered just before (1/2 to 1 hour) starting the procedure. Also, cefazoline will be administered, if necessary, at appropriate intervals during the procedure.
In patients for whom infection at the surgical site may pose a significant risk (e.g., open-heart surgery and prosthetic joint replacement), prophylactic administration of cefazoline may be continued for 3 to 5 days after surgery. If signs of infection appear, samples should be taken for culture to identify the causative agent and initiate appropriate therapy.
Patients with renal insufficiency
Cefazoline can be used in patients with renal insufficiency once the dose has been adjusted according to the doctor's recommendations.
Duration of treatment
The duration of treatment depends on the course of the disease. According to the general principles of antibiotic therapy, cefazoline should be continued for at least 2 to 3 days after the fever has subsided or the test for eradication of the causative agent has been obtained.
Method of administration
Cefazoline is administered by deep intramuscular injection.
If you use more Cefazoline Normon than you should
Consult your doctor or pharmacist. The administration of large, inappropriate doses of parenteral cephalosporins may cause seizures, especially in patients with renal insufficiency. It is necessary to reduce the dose when renal function is impaired (see section 3. How to use Cefazoline Normon). If seizures occur, the administration of the medicine should be stopped immediately; anticonvulsant treatment may be administered if clinically indicated. Hemodialysis may be considered in case of massive overdose.
In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone 91 562 04 20, indicating the medicine and the amount used.
If you forget to use Cefazoline Normon
Do not take a double dose to make up for forgotten doses.
If you stop treatment with Cefazoline Normon

If you have any doubts about the use of this product, ask your doctor or pharmacist.
