Cefdinir — Uses, Dosage, Side Effects & Safety

Drug class: Third-generation cephalosporin antibiotic

Overview

Cefdinir is an antibiotic used to treat a variety of bacterial infections, including those affecting the respiratory tract (such as pneumonia, bronchitis, and sinusitis), skin, throat, and ears. It is not effective against viral infections like the common cold or flu. Cefdinir works by stopping the growth of bacteria. It belongs to the cephalosporin class of antibiotics, which disrupt the formation of bacterial cell walls, leading to the death of the bacteria. Key points for patients: Always complete the full course of cefdinir as prescribed, even if you feel better before finishing. Stopping early can lead to the infection returning or becoming resistant. Let your healthcare provider know about any allergies, especially to antibiotics, and all medications or supplements you are taking.
