Omnicef pharmacologic effect

Omnicef (cefdinir) is an oral cephalosporin (broad-spectrum antibiotic). This drug has become one of the most widely prescribed antibiotics for the treatment of pediatric infections.

Omnicef is approved for the treatment of pharyngitis or tonsillitis in children and adults, and also for the treatment of uncomplicated skin infections. It is also approved for use in pneumonia, acute exacerbations of chronic bronchitis and acute maxillary sinusitis in adolescents and adults.

Cefdinir is a semisynthetic cephalosporin, which is active against a number of gram-positive and gram-negative aerobic bacteria. Cefdinir shows activity against the following bacteria:

  • Gram-positive microorganisms (Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus Pyogenes);
  • Gram-negative microorganisms (Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis).

Contraindications and warnings

Cefdinir is contraindicated in patients with severe hypersensitivity reactions to cephalosporins.

Caution should be exercised when using cefdinir in patients with hypersensitivity to beta-lactam antibiotics.

Just like other antibiotics, cefdinir may affect the bacterial flora of the gastrointestinal tract and lead to diarrhea.

Cefdinir may be administered during pregnancy (based on clinical need).

What should you know about Omnicef side effects?

Drug interactions

Cefdinir should not be taken together with antacids containing magnesium or aluminum.

Additives containing iron can reduce the absorption of cefdinir (from 30 to 80%). Patients treated simultaneously with cefdinir and preparations containing iron may have symptoms associated with stool color changes. If any change is accompanied by abdominal pain, diarrhea or fever, patients should discontinue treatment and immediately contact their health care provider.

It is not recommended to use probenecid during treatment with cefdinir. Probenecid violates the renal excretion of cefdinir.
