From the Research

Omnicef (cefdinir) is typically dosed at 300 mg twice daily or 600 mg once daily for adults for most common infections, with a treatment duration of 5-10 days depending on the infection type. For children, the recommended dose is 7 mg/kg every 12 hours or 14 mg/kg once daily, not exceeding the adult dose 2. Dosage adjustments are necessary for patients with renal impairment; those with creatinine clearance less than 30 mL/min should receive 300 mg once daily. Omnicef should be taken with or without food, though taking it with food may improve gastrointestinal tolerance. The medication works by inhibiting bacterial cell wall synthesis, making it effective against many common respiratory, skin, and urinary tract infections. Some key points to consider when prescribing Omnicef include:

  • The drug's broad spectrum of activity against many gram-negative and gram-positive aerobic organisms, including Streptococcus pneumoniae, Staphylococcus aureus, Streptococcus pyogenes, Haemophilus influenzae, and Moraxella catarrhalis 3
  • Its stability to hydrolysis by common beta-lactamases, making it effective against beta-lactamase-producing strains of H. influenzae and M. catarrhalis 2
  • The importance of completing the full course of antibiotics, even if symptoms improve before completion, to prevent antibiotic resistance and ensure complete eradication of the infection. Common side effects include diarrhea, nausea, and rash, and patients should be monitored for these adverse events 2, 3. Overall, Omnicef is a safe and effective treatment option for a range of infections, and its dosing regimen can be tailored to the individual patient's needs.
