Cefadroxil for Otitis Media
Cefadroxil is not recommended for the treatment of acute otitis media in pediatric patients; amoxicillin at 80-90 mg/kg/day remains the first-line antibiotic of choice. 1, 2
Why Cefadroxil Is Not Appropriate
Cefadroxil is a first-generation cephalosporin that lacks adequate coverage against the primary pathogens causing acute otitis media, particularly Haemophilus influenzae and Moraxella catarrhalis, which are frequently beta-lactamase producers. 1
The most common bacteria causing AOM in children are Streptococcus pneumoniae (including penicillin-resistant strains), Haemophilus influenzae, and Moraxella catarrhalis. 1
None of the current guidelines from the American Academy of Pediatrics, American Academy of Family Physicians, or American Academy of Otolaryngology-Head and Neck Surgery recommend cefadroxil for acute otitis media. 1, 2, 3
First-Line Treatment Algorithm
For All Children with Confirmed AOM:
Amoxicillin 80-90 mg/kg/day divided into 2-3 doses is the mandatory first-line treatment, providing optimal coverage against penicillin-resistant S. pneumoniae. 1, 2
Treatment duration should be 10 days for children under 2 years of age and 5-7 days for children over 2 years with uncomplicated cases. 1, 2
Immediate antibiotic therapy is mandatory for all infants under 6 months, regardless of severity, due to higher risk of complications. 1
Age-Specific Considerations:
Children under 2 years with bilateral AOM require immediate antibiotics without observation. 1
Children 6-23 months with nonsevere unilateral AOM may be considered for watchful waiting only with assured follow-up within 48-72 hours. 1
Children over 2 years with nonsevere symptoms may be observed for 48-72 hours if follow-up is reliable. 1, 2
Appropriate Cephalosporin Alternatives (When Indicated)
For Non-Type I Penicillin Allergy:
Cefdinir, cefpodoxime, or cefuroxime are the recommended cephalosporin alternatives, not cefadroxil. 1, 2, 3
These second- and third-generation cephalosporins provide excellent coverage against S. pneumoniae, H. influenzae, and M. catarrhalis, including beta-lactamase-producing strains. 3, 4
Cefdinir has demonstrated 72.7% eradication rates for penicillin-intermediate S. pneumoniae and 50% for penicillin-resistant strains in tympanocentesis-documented AOM. 4
For Treatment Failure:
If symptoms persist or worsen after 48-72 hours of amoxicillin, switch to amoxicillin-clavulanate 90 mg/kg/day (of the amoxicillin component). 1, 2
Reassessment with proper visualization of the tympanic membrane is mandatory to confirm diagnosis. 1, 2
Special Clinical Situations Requiring Amoxicillin-Clavulanate Instead of Amoxicillin:
Child received amoxicillin within the previous 30 days. 1
Concurrent purulent conjunctivitis (suggests H. influenzae infection). 2
History of recurrent AOM unresponsive to amoxicillin. 1
Common Pitfalls to Avoid
Do not prescribe antibiotics without adequate visualization of the tympanic membrane to confirm middle ear inflammation and effusion. 1, 2
Do not use first-generation cephalosporins like cefadroxil for AOM, as they lack coverage against common beta-lactamase-producing pathogens. 1
Do not forget pain management—analgesics should be provided systematically, especially during the first 24 hours, regardless of antibiotic use. 1, 2, 3
Do not fail to reassess within 48-72 hours if symptoms persist or worsen. 1, 2
Do not use antibiotics for otitis media with effusion (OME) unless it persists beyond 3 months with complications. 2
