Cefazolina Normon contains sodium

This medication contains 96 mg of sodium (main component of table salt/for cooking) in each 2g vial of cefazolin. This is equivalent to 4.8% of the maximum daily sodium intake recommended for an adult.

Follow exactly the administration instructions of this medication indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

Remember to use your medication.

Your doctor will indicate the duration of your treatment with Cefazolina Normon 2 g Injectable.

The normal dose is:

Adults and children over 12 years:in the case of mild infections 500 mg every 8 hours; in moderate to severe infections 500 mg to 1 g every 6 or 8 hours; in more severe infections 1 to 1.5 g every 6 hours.

Children (under 12 years and over 1 year):a total daily dose of 25 to 50 mg per kg of 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.

Prophylactic treatment

To prevent postoperative infection in surgery, the recommended doses are as follows:

a) 1 g i.v. administered 1/2 to 1 hour before starting surgery.

b) for prolonged surgical procedures (e.g., 2 hours or more) 0.5 to 1 g i.v. during surgery (dosage will be adjusted depending on the duration of the intervention).

c) 500 mg to 1 g i.v. every 6 to 8 hours for 24 postoperative hours.

It is essential that the preoperative dose be administered just before (1/2 to 1 hour) starting the intervention. Additionally, cefazolina will be administered, if necessary, at appropriate intervals during the intervention.

In surgical operations where the presence of infection can be especially devastating (e.g., open-heart surgery and prosthetic arthroplasty) the prophylactic administration of cefazolina may be continued for 3 to 5 days after surgery. If there are signs of infection, samples should be obtained for culture, in order to identify the causal germ, in order to establish the appropriate therapy.

Patients with renal insufficiency

Cefazolina can be used in patients with renal insufficiency once the dose has been adjusted according to the prescriber's recommendations.

If you use more Cefazolina Normon than you should

Consult your doctor or pharmacist. The administration of large inappropriate doses of parenteral cephalosporins can cause convulsions, especially in patients with renal insufficiency. It is necessary to reduce the dose when renal function is altered (see section 3. How to use Cefazolina Normon). If convulsions occur, discontinue administration of the medication immediately; anticonvulsant treatment may be administered if clinically indicated. Hemodialysis may be considered in cases 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 medication and the amount used.

If you forgot to use Cefazolina Normon

Do not take a double dose to compensate for the missed doses.
