From the Guidelines

The recommended first-line treatment for an ear infection is typically oral amoxicillin at a dose of 80-90 mg/kg/day divided into two doses for 5-10 days, with the duration depending on the patient's age and severity of symptoms, as it is the most effective option against the common bacterial causes of ear infections, including Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis 1.

Key Considerations

  • Amoxicillin is preferred due to its effectiveness, safety, low cost, and narrow microbiologic spectrum 1.
  • For patients who have received amoxicillin in the previous 30 days, or those with concurrent conjunctivitis, amoxicillin-clavulanate may be used as an alternative 1.
  • In cases of penicillin allergy, alternatives such as cefdinir, cefuroxime, or cefpodoxime may be considered, as they have a low risk of cross-reactivity with penicillin 1.

Treatment Options

  • Amoxicillin: 80-90 mg/kg/day divided into two doses for 5-10 days 1.
  • Amoxicillin-clavulanate: 90 mg/kg/day of amoxicillin, with 6.4 mg/kg/day of clavulanate in 2 divided doses 1.
  • Cefdinir: 14 mg/kg/day in 1 or 2 doses 1.
  • Cefuroxime: 30 mg/kg/day in 2 divided doses 1.

Important Notes

  • Patients should complete the full course of antibiotics even if symptoms improve before finishing the prescription.
  • Pain management with over-the-counter analgesics like acetaminophen or ibuprofen is also important.
  • The choice of antibiotic should be based on the anticipated clinical response and the microbiologic flora likely to be present 1.

From the FDA Drug Label

Adults and Pediatric Patients Upper Respiratory Tract Infections of the Ear, Nose, and Throat:Amoxicillin for oral suspension is indicated in the treatment of infections due to susceptible (ONLY β-lactamase–negative) isolates of Streptococcusspecies. (α-and β-hemolytic isolates only), Streptococcus pneumoniae, Staphylococcusspp., or Haemophilus influenzae.

The recommended first-line treatment for an ear infection is amoxicillin. There is no direct comparison or mention of augmentin in the provided drug label, so no conclusion can be drawn about which is better between the two. According to the label, amoxicillin is indicated for the treatment of upper respiratory tract infections, including ear infections, due to susceptible isolates of certain bacteria 2.

From the Research

Treatment Options for Ear Infections

The choice between Augmentin (amoxicillin/clavulanic acid) and amoxicillin for the treatment of ear infections depends on various factors, including the severity of the infection, the patient's age, and the presence of resistant pathogens.

  • Efficacy of Amoxicillin/Clavulanic Acid: Studies have shown that amoxicillin/clavulanic acid is effective in treating ear infections, particularly those caused by resistant strains of Streptococcus pneumoniae 3, 4.
  • Comparison with Amoxicillin: Amoxicillin is often recommended as the first-line treatment for uncomplicated ear infections, while amoxicillin/clavulanic acid is recommended for more severe cases or those that do not respond to amoxicillin alone 5.
  • Clinical Trials: A study comparing the efficacy of high-dose amoxicillin/clavulanic acid with cefdinir in the treatment of ear infections found that amoxicillin/clavulanic acid was more effective in achieving clinical cure 6.
  • Safety and Tolerability: Amoxicillin/clavulanic acid is generally well-tolerated, with mild gastrointestinal disturbances being the most common adverse events 3, 7.

Recommendations

Based on the available evidence, amoxicillin/clavulanic acid (Augmentin) may be considered a better treatment option for ear infections, particularly in cases where resistant pathogens are suspected or the patient has not responded to amoxicillin alone 3, 4, 5, 6. However, the choice of treatment ultimately depends on the specific clinical circumstances and the patient's individual needs.

  • First-Line Treatment: Amoxicillin is often recommended as the first-line treatment for uncomplicated ear infections 5.
  • Alternative Treatment: Amoxicillin/clavulanic acid may be considered as an alternative treatment option for patients who do not respond to amoxicillin alone or have severe infections 5, 6.
