How Does Cefazolin Work?

As mentioned, cefazolin is a cephalosporin antibiotic. Cephalosporins are part of a larger group of medications known as beta-lactam antibiotics, named after the ring-like "lactam" structure of these drugs. Cefazolin works by stopping bacteria from making cell walls, which eventually causes the bacteria to die. Cephalosporins are related to penicillin. Cefazolin is usually classified as a "first-generation" cephalosporin.
 

When and How to Use This Medicine

Some general considerations to keep in mind during treatment with cefazolin include the following:
 
  • This medication is given by IV or by intramuscular injection. It is usually given every 6 to 12 hours.
 
  • For serious infections, it is usually best to give this drug by IV rather than an intramuscular injection.
 
  • Cefazolin is often given for a few days after the infection has cleared up. For serious infections, an even longer treatment course may be recommended.
