What is the treatment for acute otitis media in a 4-year-old child with a hypersensitivity reaction to Amoxicillin (amoxicillin)?

From the Guidelines

For a 4-year-old with otitis media who has an amoxicillin allergy, I recommend cefdinir (14 mg/kg/day divided into 1-2 doses for 10 days) as a first-line alternative, considering its effectiveness and low risk of cross-reactivity with penicillin allergy, as supported by recent data 1. When managing otitis media in a child with an amoxicillin allergy, it is crucial to consider the severity of the allergy and the potential for cross-reactivity with other antibiotics.

Key Considerations

• The American Academy of Pediatrics (AAP) and the American Academy of Family Physicians (AAFP) recommend amoxicillin as the first-line treatment for acute otitis media (AOM) due to its effectiveness, safety, and narrow microbiologic spectrum 1.
• However, for patients allergic to amoxicillin, alternative treatments such as cefdinir, cefpodoxime, or cefuroxime can be considered, with cefdinir being a preferred option due to its better coverage against common ear pathogens and low risk of cross-reactivity with penicillin allergy 1.
• The risk of cross-reactivity between penicillins and cephalosporins, such as cefdinir, is lower than historically reported, with recent studies suggesting a negligible risk of cross-reactivity with second- and third-generation cephalosporins 1.

Treatment Recommendations

• Cefdinir (14 mg/kg/day divided into 1-2 doses for 10 days) is a recommended first-line alternative for patients with non-severe penicillin allergies 1.
• Azithromycin (10 mg/kg on day 1, followed by 5 mg/kg once daily for days 2-5) may be considered as an alternative for patients with severe penicillin allergies or those who cannot tolerate cefdinir 1.
• Supportive care, including the use of acetaminophen or ibuprofen for pain and fever, keeping the child well-hydrated, and elevating the head during sleep, is also important in managing otitis media.
• A follow-up appointment should be scheduled in 48-72 hours to assess the child's response to treatment and adjust the management plan as needed.

From the FDA Drug Label

The recommended dose of azithromycin for oral suspension for the treatment of pediatric patients with acute otitis media is 30 mg/kg given as a single dose or 10 mg/kg once daily for 3 days or 10 mg/kg as a single dose on the first day followed by 5 mg/kg/day on Days 2 through 5. For a 4-year-old patient with an allergy to amoxicillin, azithromycin can be considered as an alternative treatment for otitis media.

• The dose of azithromycin for a 4-year-old patient with otitis media would depend on the patient's weight.
• According to the dosage guidelines, for a patient weighing between 10-20 kg (approximately 22-44 lbs), the recommended dose is 15 mL (300 mg) for the 1-day regimen or 5 mL (100 mg) per day for the 3-day regimen.
• It is essential to consult a healthcare professional to determine the appropriate dose and treatment duration for the patient. 2 2 2

From the Research

Treatment Options for Otitis Media in a 4-Year-Old with an Allergy to Amoxicillin

• The patient's allergy to amoxicillin requires alternative antibiotic treatments to be considered 3, 4, 5, 6, 7.
• Clarithromycin is a potential option, as it has been shown to be effective in treating acute otitis media in children, with a clinical success rate of 93% 3.
• Azithromycin is another alternative, with studies demonstrating its comparable efficacy to amoxicillin/clavulanate in treating otitis media in children, and a lower rate of adverse events 5, 7.
• Trimethoprim-sulfamethoxazole has also been shown to be effective in treating acute otitis media, with a higher combined rate of cure and improvement compared to amoxicillin-clavulanate in one study 6.

Considerations for Antibiotic Selection

• The selection of an antibiotic should be based on the suspected or confirmed causative pathogen, as well as the patient's allergy history and potential side effects of the medication 4, 5, 6, 7.
• Pharmacokinetic/pharmacodynamic principles should also be considered in selecting antibiotics for otitis media 4.
• The increasing prevalence of drug-resistant pathogens, such as Streptococcus pneumoniae, should be taken into account when choosing an antibiotic 4, 5.

Alternative Treatments and Prevention

• Tympanocentesis may be useful in identifying the causative pathogen and guiding antibiotic selection 4.
• The pneumococcal conjugate vaccine has been shown to be effective in preventing recurrent otitis media and should be considered for children at risk 4.
