Cefdinir is what generation?

What “generation” is cefdinir?

Cefdinir is a third-generation cephalosporin. [1]

Why people ask about “generation”

Cephalosporin “generation” is a rough way to describe how the drug’s antibacterial spectrum evolved across older vs newer versions of the class. Cefdinir is placed in the third generation based on its spectrum compared with first- and second-generation cephalosporins. [1]

Common confusion: cefdinir vs other cephalosporins

If you’re comparing it to other cephalosporins, check the label or reference for the specific drug:
- 1st generation: more focused on gram-positive coverage
- 2nd generation: broader gram-negative coverage than 1st
- 3rd generation (includes cefdinir): generally stronger gram-negative activity than earlier generations

(Those general trends are the reason people classify them by generation, even though each drug has its own specifics.) [1]
