1. What Cefazolin Dali Pharma is and what it is used for

Cefazolin Dali Pharma contains the active substance cefazolin (as cefazolin sodium).
Cefazolin is an antibiotic belonging to the group of cephalosporins, which have a bactericidal effect.
Cefazolin Dali Pharma is used to treat bacterial infections caused by bacteria sensitive to cefazolin. Cefazolin Dali Pharma is used to treat the following infections:

• Skin and soft tissue infections
• Bone and joint infections

Cefazolin Dali Pharma is also used before, during, or after surgery to prevent infections in patients.

2. Important information before using Cefazolin Dali Pharma

When not to use Cefazolin Dali Pharma

• If the patient is allergic to cefazolin sodium
• If the patient is allergic to any cephalosporin
• If the patient has had a severe allergic reaction (hypersensitivity) to any beta-lactam antibiotic (penicillins, monobactams, and carbapenems) in the past

Warnings and precautions

Before starting treatment with Cefazolin Dali Pharma, discuss it with your doctor or pharmacist

• if the patient has a tendency to allergies (e.g., hay fever or asthma), as the risk of severe allergic reactions to Cefazolin Dali Pharma is higher.
• if the patient has had an allergic reaction to other beta-lactam antibiotics (e.g., penicillins) in the past, as the risk of an allergic reaction to Cefazolin Dali Pharma is higher (see section 4).
• if the patient has kidney or liver function disorders.
• if the patient has bleeding disorders (e.g., hemophilia) or if the patient is currently at risk of bleeding disorders [due to parenteral nutrition, malnutrition, liver or kidney function disorders, decreased platelet count, which increases the risk of bleeding or bruising (thrombocytopenia), or the use of anticoagulant medications (e.g., heparin)].
• if the patient has diseases that cause bleeding (e.g., stomach and duodenal ulcers).
• if the patient experiences severe, persistent diarrhea during or after treatment with Cefazolin Dali Pharma (see section 4). In such cases, contact your doctor immediately. Do not take medications that suppress intestinal motility without consulting your doctor.
• if the patient has hypertension, consider the sodium content in Cefazolin Dali Pharma

Cefazolin Dali Pharma must not be administered into the spinal canal (intrathecally), as severe central nervous system toxicity (including seizures) has been reported.
Prolonged use of Cefazolin Dali Pharma may cause superinfections. Your doctor will then prescribe appropriate treatment.
Cefazolin Dali Pharma may give false-positive results in some laboratory tests.

Children

Cefazolin should not be used in premature infants and newborns under 1 month of age, as the safety of the medicine in this age group has not been established.

Cefazolin Dali Pharma and other medicines

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. This includes medicines available without a prescription.
Pay special attention if you are taking any of the following medicines:

• Antibiotics that inhibit bacterial growth, such as tetracyclines, sulfonamides, erythromycin, and chloramphenicol.
• Probenecid (used to treat joint disease and gout), as the level of cefazolin in the patient's blood may increase.
• Anticoagulant medications (medicines that prevent blood clotting, such as warfarin or heparin), as their concurrent use with cephalosporins may rarely lead to coagulation disorders. Therefore, during concurrent use of cefazolin and anticoagulant medications, coagulation should be monitored.
• Certain diuretics (e.g., furosemide), as their concurrent use with cefazolin may increase the toxic effect on the kidneys. Kidney function should be monitored during concurrent use of cefazolin and these types of medications.
• Medicines that are potentially toxic to the kidneys. Cefazolin may increase the toxic effect on the kidneys of certain antibiotics (aminoglycosides) and diuretics (e.g., furosemide). Concurrent use of Cefazolin Dali Pharma and one of the above-mentioned medicines requires regular monitoring of kidney function, especially in patients with kidney function disorders.
• Oral contraceptives (birth control pills), as antibiotics reduce their effectiveness.

Cephalosporins like cefazolin may interfere with the conversion and utilization of vitamin K1 in the body, especially in patients with vitamin K1 deficiencies. During treatment with Cefazolin Dali Pharma, your doctor may recommend vitamin K1 supplementation.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a baby, consult your doctor before using this medicine.
Pregnancy
Cefazolin crosses the placental barrier and may affect the unborn child. Therefore, cefazolin should only be used during pregnancy if it is absolutely necessary and after careful consideration by your doctor of the benefit-to-risk ratio.
Breastfeeding
Cefazolin passes into human milk in small amounts. Therefore, breastfeeding should be discontinued during treatment with Cefazolin Dali Pharma.
Fertility
In animal studies, no effect on fertility has been observed.

Driving and using machines

Cefazolin has no influence or negligible influence on the ability to drive and use machines. However, during treatment, side effects (e.g., allergic reactions, non-systemic dizziness) may occur that can affect these activities (see also section 4).

Cefazolin Dali Pharma contains sodium

Cefazolin Dali Pharma contains 101.2 mg of sodium (the main component of table salt) per 2 g dose.
This corresponds to 5.1% of the maximum recommended daily sodium intake in the diet for adults. This should be taken into account in patients on a sodium-restricted diet.

3. How to use Cefazolin Dali Pharma

This medicine should be administered to the patient by a qualified person, i.e., a doctor or nurse. This medicine should always be used as directed by your doctor. In case of doubts, consult your doctor.
Cefazolin Dali Pharma 2 g, after reconstitution, is administered intravenously in the form of an infusion. Your doctor will inform you about the required duration of treatment and the frequency of Cefazolin Dali Pharma administration.

Recommended dose

The recommended dose of Cefazolin Dali Pharma is determined by your doctor based on the severity of the infection, body weight, and age, as well as kidney function.

Adults and adolescents (over 12 years old and weighing ≥ 40 kg)

• Infections caused by bacteria sensitive to the medicine: 1 to 2 g per day divided into 2-3 equal doses (1 dose every 8 or 12 hours).
• Infections caused by bacteria less sensitive to the medicine: 3 to 4 g per day divided into 3-4 equal doses (1 dose every 6 or 8 hours).
• The daily dose of cefazolin can be increased to 6 g divided into 3 or 4 equal doses (1 dose every 6 or 8 hours).

Use in children and adolescents

Premature infants and newborns under 1 month old

The safety of the medicine in premature infants and newborns under 1 month old has not been established.

Children over 1 month old

• Infections caused by bacteria sensitive to the medicine: 25-50 mg/kg body weight per day divided into 2-4 equal doses (1 dose every 6, 8, or 12 hours).
• Infections caused by bacteria less sensitive to the medicine: up to 100 mg of cefazolin per kg body weight per day divided into 3 or 4 equal doses (1 dose every 6 or 8 hours).

Use in elderly patients

Dose adjustment is not necessary in elderly patients with normal kidney function

Special dosage recommendations

Surgical prophylaxis
1 g of cefazolin 30-60 minutes before surgery. In cases of prolonged operations (2 hours or longer), an additional dose of 0.5-1 g of cefazolin during surgery.
Patients with renal impairment
In patients with renal impairment, cefazolin excretion is slowed down. Therefore, your doctor will adjust the dosage according to the degree of renal impairment by reducing the maintenance dose or prolonging the interval between doses.

Duration of treatment

The duration of treatment depends on the severity of the infection and the patient's recovery.

Using a higher dose of Cefazolin Dali Pharma than recommended

Contact your doctor or nurse immediately if you think you have been given a higher dose than recommended.
Since the medicine is administered by a doctor or nurse, it is unlikely that the patient will be given a higher dose than recommended. Symptoms of overdose include systemic dizziness, feeling of pricking, itching, or tingling without an apparent cause (paresthesia) and (or) headache.
In patients with kidney disease, seizures may occur. Contact your doctor immediately if you experience any of the above symptoms! In emergency cases, immediate medical attention is required to treat overdose symptoms.

Missing a dose of Cefazolin Dali Pharma

Contact your doctor immediately if you think you have missed a dose of the medicine.
Missed doses should still be administered. Do not take a double dose to make up for a missed dose. Missed doses should only be administered if the time before the next regular dose is long enough.

Stopping or prematurely ending treatment with Cefazolin Dali Pharma

Small doses of the medicine, irregular dosing, or premature termination of treatment may affect the treatment outcome or cause a relapse of the infection, which is more difficult to treat. Follow your doctor's instructions.
In case of any further doubts related to the use of this medicine, consult your doctor.
