What is Cefdinir?
Cefdinir is a prescription cephalosporin antibiotic used to treat a variety of bacterial infections including ear infections (otitis media), sinus infections, strep throat, bronchitis, pneumonia, and certain skin infections. It works by disrupting the bacteria's ability to form a cell wall, causing them to die. Cefdinir is taken orally as a capsule or liquid suspension and is suitable for both adults and children. Typical adult doses are 300 mg twice daily or 600 mg once daily for 5–10 days. Completing the full course of antibiotics — even if you feel better — is essential to prevent the infection from returning.

What Is Cefdinir?
Cefdinir is an oral, third-generation cephalosporin antibiotic used to treat mild-to-moderate bacterial infections in adults and children. It is broad-spectrum — effective against both gram-positive bacteria (like Streptococcus and Staphylococcus) and some gram-negative bacteria — making it useful for a wide range of common infections.
What Does Cefdinir Treat?
- Acute otitis media (ear infections) — particularly common in children
- Acute bacterial sinusitis — sinus infections that do not resolve on their own
- Strep throat (pharyngitis/tonsillitis)
- Acute exacerbations of chronic bronchitis
- Community-acquired pneumonia (mild to moderate)
- Uncomplicated skin and soft-tissue infections
How Does Cefdinir Work?
Like all beta-lactam antibiotics, cefdinir works by binding to penicillin-binding proteins (PBPs) on the bacterial cell membrane. This inhibits the final step of cell wall synthesis, causing the cell wall to weaken and the bacteria to burst and die.
Dosage Overview
- Adults and adolescents (13+ years): 300 mg every 12 hours or 600 mg once daily for 5–10 days
- Children 6 months–12 years: 7 mg/kg every 12 hours or 14 mg/kg once daily (max 600 mg/day)
Cefdinir may turn stools red-brown when taken with iron-containing products — this is harmless. Complete the full course.
