Table of contents of the leaflet:
The medicine contains the active substance cefazolin, which is an antibiotic. Cefazolin MIP Pharma is used to treat bacterial infections caused by microorganisms sensitive to cefazolin, such as:
Cefazolin may also be used before, during, or after surgery to prevent potential infections.
Before starting treatment with Cefazolin MIP Pharma, discuss it with your doctor.
Tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
Be particularly careful when taking the following medicines:
If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor before using this medicine.
Cefazolin crosses the placental barrier and may affect the unborn child. Therefore, cefazolin should only be used during pregnancy if absolutely necessary and after careful consideration by the doctor of the benefit-to-risk ratio.
Cefazolin passes into breast milk in small amounts. Therefore, breastfeeding should be discontinued during treatment with Cefazolin MIP Pharma.
Cefazolin MIP Pharma has no or negligible influence on the ability to drive and use machines.
The medicine contains 101.6 mg of sodium (the main component of table salt) per vial, which corresponds to 5.1% of the maximum recommended daily sodium intake in the diet for adults.
This medicine should always be used as directed by your doctor or pharmacist. If you have any doubts, consult your doctor. The medicine is administered by injection or infusion (into a vein) after prior dissolution. The doctor will decide on the duration and frequency of Cefazolin MIP Pharma administration.
infections caused by bacteria sensitive to the medicine: 1 to 2 g per day divided into 2 or 3 doses.
infections caused by bacteria less sensitive to the medicine: 3 to 4 g per day divided into 3 or 4 doses.
It is possible to increase the daily dose of cefazolin to 6 g administered in 3 or 4 equal doses.
The safety of the medicine in infants under 1 month has not been established.
infections caused by bacteria sensitive to the medicine: 25 to 50 mg per kg of body weight per day divided into 2 to 4 single doses, every 6, 8, or 12 hours.
infections caused by bacteria less sensitive to the medicine: up to 100 mg of cefazolin per kg of body weight per day divided into 3 or 4 single doses, every 6 to 8 hours.
Cefazolin should not be used in children under 1 month of age.
No dose adjustment is necessary in elderly patients with normal kidney function.
Prevention of infections during surgical procedures
1 g of cefazolin 30-60 minutes before the surgical procedure.
In the case of prolonged operations (2 hours or longer), an additional dose of 0.5 to 1 g of cefazolin during the procedure.
Patients with renal impairment
In patients with renal impairment, cefazolin excretion is slowed down. Therefore, the doctor will adjust the dosage according to the degree of renal impairment by reducing the maintenance dose or prolonging the interval between doses.
The duration of treatment depends on the severity of the infection and the patient's recovery.
Do not take a double dose to make up for a missed dose. A missed dose should only be taken if the time before the next regular dose is long enough.
Symptoms of overdose include headache, dizziness, burning or tingling sensation on the skin (paresthesia), restlessness (irritation), involuntary muscle contractions or muscle group contractions (myoclonus), and seizures. If you experience any of these symptoms, contact your doctor.
In emergency situations, immediate medical attention is required to treat overdose symptoms.
Small doses, irregular dosing, or premature discontinuation of treatment may affect the outcome of treatment or cause a relapse of the infection, which may be more difficult to treat. Follow your doctor's instructions.
If you have any further doubts about using this medicine, consult your doctor, pharmacist, or nurse.

Information intended for healthcare professionals only:
Cefazolin MIP Pharma for injection and infusion can be administered as a slow intravenous injection or, after dilution, as an intravenous infusion.
In the case of any administration route, refer to the information in the table, which presents additional volumes and concentrations of solutions that may be useful in situations where divided doses are required.
Intravenous injection:
2 g of powder should be dissolved in at least 10 ml of water for injection or in one of the solvents listed below.
Content per vial | Minimum amount of solvent to be added | Approximate concentration |
2 g | 10 ml | 200 mg/ml |
Cefazolin should be injected slowly into a vein over 3-5 minutes. Injections lasting less than 3 minutes are contraindicated. Injections should be administered directly into a vein or into a set through which the patient is receiving intravenous solutions.
Single doses greater than 1 g should be administered as an intravenous infusion over 30 to 60 minutes.
Intravenous infusion
2 g of powder should be dissolved in 8 ml of water for injection and diluted with a compatible solvent to a volume of 50-100 ml.
Content per vial | Dissolution | Dilution | Approximate concentration |
Minimum amount of solvent to be added | Amount of solvent to be added | ||
2 g | 8 ml | 50 ml - 100 ml | 34 mg/ml - 19 mg/ml |
If smaller doses are required, it is recommended to use half of the dissolved solution (about 4 ml from 1 g of cefazolin, i.e., half of the vial content) and add a compatible solvent to the target volume of 100 ml (resulting concentration of about 10 mg/ml). The required amount of such a diluted solution can then be administered to the patient over a specified period.
Compatibility with intravenous fluids
The following solvents are suitable for preparing the solution:
The dissolved solution is clear, light yellow, and should be protected from light.
Only use clear solutions without contaminants.
Shelf life of the prepared infusion solution
The prepared solution shows chemical and physical stability for 12 hours at 25°C and for 24 hours at 2-8°C. From a microbiological point of view, the prepared solution should be used immediately after preparation. If the solution is not used immediately, the time and conditions of storage after opening are the responsibility of the healthcare professional.
The dissolved product is only suitable for single use. Any unused product or waste material should be disposed of in accordance with local regulations.
The contents of 1 vial (2000 mg of cefazolin) are dissolved in 10 ml of a compatible solvent (i.e., a concentration of about 200 mg/ml). The following table shows the appropriate volume of this solution to be used along with the dose in mg.

Children with renal impairment (like adults) may require lower doses to avoid accumulation of the medicine.
A lower dose can be selected based on blood test results. If this is not possible, the dose can be determined based on creatinine clearance according to the following guidelines.
In children with moderate renal impairment (creatinine clearance 40-20 ml/min), it is sufficient to use 25% of the usual daily dose divided into doses every 12 hours.
In children with severe renal impairment (creatinine clearance 20-5 ml/min), it is sufficient to use 10% of the usual daily dose divided into doses every 24 hours.
All of the above guidelines apply after the initial dose.
