WHY is this medicine prescribed?
Cefazolin injection is used to treat certain infections caused by bacteria including skin, bone, joint, genital, blood, heart valve, respiratory tract (including pneumonia), biliary tract, and urinary tract infections. Cefazolin injection also may be used before, during, and sometimes for a brief period after surgery in order to prevent the patient from getting an infection. Cefazolin injection is in a class of medications called cephalosporin antibiotics. It works by killing bacteria.
Antibiotics such as cefazolin injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
HOW should this medicine be used?
Cefazolin injection comes as a powder to be mixed with liquid, or as a premixed product, to be injected intravenously (into a vein) over a period of 30 minutes. Cefazolin injection can also be given intramuscularly (into a muscle). It is usually given every 6, 8, or 12 hours. The length of your treatment depends on the type of infection you have and how your body responds to the medication.
You may receive cefazolin injection in a hospital or you may administer the medication at home. If you will be receiving cefazolin injection at home, your healthcare provider will show you how to use the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions.
You should begin to feel better during the first few days of treatment with cefazolin injection. If your symptoms do not improve or get worse, call your doctor.
Use cefazolin injection until you finish the prescription, even if you feel better. If you stop using cefazolin injection too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Are there OTHER USES for this medicine?
Cefazolin injection is also sometimes used for certain penicillin allergic patients who have a heart condition and are having a dental or upper respiratory tract (nose, mouth, throat, voice box) procedure, in order to prevent them from developing a heart valve infection. Cefazolin injection is also sometimes used to treat certain penicillin allergic women who are in labor in order to prevent the newborn from developing an infection.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
