From the Guidelines

The recommended antibiotic treatment for epiglottitis is a third-generation cephalosporin such as ceftriaxone (1-2g IV every 24 hours) or cefotaxime (1-2g IV every 8 hours), typically administered for 7-10 days. This recommendation is based on the most recent and highest quality study available, which prioritizes the treatment of Haemophilus influenzae type b, Streptococcus pneumoniae, and Staphylococcus aureus, the most common causative organisms of epiglottitis 1.

For patients with severe penicillin allergy, alternatives include levofloxacin (750mg IV daily) or clindamycin (600-900mg IV every 8 hours) plus a fluoroquinolone. Treatment should be initiated immediately after securing the airway and obtaining blood cultures, without waiting for culture results. Empiric coverage should target the most common causative organisms, and once culture results are available, therapy can be narrowed based on susceptibility.

Some key points to consider in the treatment of epiglottitis include:

  • The importance of securing the airway before initiating treatment
  • The need for hospitalization with close airway monitoring due to the risk of rapid airway obstruction
  • The potential for transitioning to oral antibiotics after clinical improvement
  • The importance of vaccination against H. influenzae type b, especially in adults with immunocompromise

It's worth noting that the evidence from 1 and 1 supports the use of third-generation cephalosporins as the first-line treatment for epiglottitis, and that the choice of antibiotic should be guided by local resistance patterns and patient-specific factors. However, ceftriaxone and cefotaxime remain the preferred options due to their broad spectrum of activity and favorable safety profile.

From the Research

Recommended Antibiotics for Epiglottitis

The following antibiotics are recommended for the treatment of epiglottitis:

  • Ceftriaxone, a third-generation cephalosporin, has been shown to be effective in treating epiglottitis in children 2, 3
  • Sulbactam/ampicillin is also an effective treatment option for acute epiglottitis in children, especially when Haemophilus influenzae type b is the causative agent 4
  • Other third and fourth generation cephalosporins, such as ceftazidime and cefoperazone, may also be effective, but their use may be limited by their susceptibility to beta-lactamases 5

Key Findings

  • Ceftriaxone has been shown to be safe and effective in treating epiglottitis, with a short course of treatment (2-5 days) being sufficient 2, 3
  • Sulbactam/ampicillin has been shown to be effective in treating epiglottitis, especially in cases where the causative agent is Haemophilus influenzae type b 4
  • The choice of antibiotic should be based on the suspected or confirmed causative agent, as well as the patient's clinical condition and medical history 2, 3, 4, 5

Antibiotic Resistance

  • Haemophilus influenzae type b, the most common causative agent of epiglottitis, has been shown to produce beta-lactamases, making it resistant to some antibiotics, such as ampicillin 4
  • The use of sulbactam/ampicillin or other beta-lactamase inhibitors may be necessary to overcome this resistance 4
  • Ceftriaxone has been shown to be effective against Haemophilus influenzae type b, including strains that produce beta-lactamases 2, 3
