How Does Ancef Work?

As mentioned, Ancef 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. Ancef works by stopping bacteria from making cell walls, which eventually causes the bacteria to die. Cephalosporins are related to penicillin. Ancef is usually classified as a "first-generation" cephalosporin.

When and How to Use It

Some general considerations to keep in mind during treatment with Ancef 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.
  • Ancef is often given for a few days after the infection has cleared up. For serious infections, an even longer treatment course may be recommended.
