Remember to use your medication.

Your doctor will determine the dose of Cefazolina based on your age, weight, the severity of the infection, and the state of your kidneys. The doctor will explain it to you.

The recommended dose is:

Adults and children over 12 years:in the case of mild infections, 500 mg every 8 hours (total daily dose would be 1.5g); in moderate to severe infections, 500 mg to 1g every 6 or 8 hours (total daily dose 3g-4g); in 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 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.

Surgical site infection prevention / postoperative in adults:

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

a) 1-2 g administered 30 minutes to 60 minutes before starting surgery.

b) for prolonged surgical procedures (e.g., 2 hours or more) of 500 mg to 1 g during surgery (dosage will be adjusted depending on the duration of the procedure).

c) of 500 mg to 1 g every 6 to 8 hours during the 24 hours postoperative.

Surgical site infection prevention / postoperative in children

In patients for whom the infection at the surgical site may pose a severe risk (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, so that appropriate therapy can be initiated.

Adults and children with reduced renal function

If you have kidney problems, you may receive a lower dose. It may be necessary to have a blood test to ensure that you have received a sufficient dose.

Treatment duration

The duration of treatment depends on the course of the disease. According to general principles of antibiotic therapy, cefazolina should be continued for at least 2 to 3 days after the fever has subsided or the causal agent has been eradicated.
