From the Guidelines
Cephalexin is not the first-line treatment for recurrent ear infections, and high-dose amoxicillin is recommended as the initial treatment. When considering the treatment of recurrent ear infections, it's crucial to prioritize the most effective and safest options. According to the American Academy of Pediatrics 1, high-dose amoxicillin is the recommended first-line treatment for most patients. This recommendation is based on amoxicillin's effectiveness against common bacterial pathogens, such as Streptococcus pneumoniae and Haemophilus influenzae, as well as its safety profile, low cost, and acceptable taste.
Some key points to consider when treating recurrent ear infections include:
- The use of high-dose amoxicillin (80-90 mg/kg per day in 2 divided doses) as the first-line treatment
- Alternative treatments, such as cefdinir, cefuroxime, or cefpodoxime, may be considered in patients with penicillin allergies or other specific conditions
- The importance of completing the full course of antibiotics, even if symptoms improve before finishing the prescription
- The potential for side effects, such as diarrhea, nausea, and allergic reactions, especially in those with penicillin allergies
It's essential to note that cephalexin, while effective against some bacterial pathogens, is not the primary recommended treatment for recurrent ear infections. However, in certain cases, such as penicillin allergies or specific bacterial susceptibilities, cephalexin may be considered as an alternative treatment option 1. Ultimately, the choice of antibiotic and treatment duration should be determined by a healthcare provider, taking into account the individual patient's needs and medical history.
From the FDA Drug Label
Cephalexin is indicated for the treatment of the following infections when caused by susceptible strains of the designated microorganisms: ... Otitis media due to Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Streptococcus pyogenes, and Moraxella catarrhalis In the therapy of otitis media, clinical studies have shown that a dosage of 75 to 100 mg/kg/day in 4 divided doses is required.
Cephalexin dosage for recurrent ear infection (otitis media):
- The recommended dosage is 75 to 100 mg/kg/day in 4 divided doses 2
- The usual adult dose is 250 mg every 6 hours, but for more severe infections, larger doses may be needed 2

From the Research
Cephalexin for Recurrent Ear Infection
- Cephalexin is a type of cephalosporin antibiotic, which is a broad class of antibiotics used to treat various infections, including ear infections 3.
- However, the provided studies do not specifically mention the use of cephalexin for recurrent ear infections.
- The studies discuss the treatment and prevention of recurrent acute otitis media (rAOM) and suggest the use of systemic antibiotics, such as amoxicillin, cefuroxime axetil, and ceftriaxone, as first-line treatments 4, 5, 6.
- One study mentions that cephalosporins, including cephalexin, have a broad spectrum of microbiologic activity and are effective against various infections, but it does not specifically address recurrent ear infections 3.
- Another study discusses the management of recurrent and persistent acute otitis media, but it does not mention cephalexin as a treatment option 5.
- A study from 2000 recommends a three-step treatment algorithm for refractory AOM, which includes amoxicillin, trimethoprim/sulfamethoxazole, or high-dose amoxicillin/clavulanate, and ceftriaxone or tympanocentesis, but it does not mention cephalexin 6.
- A more recent study from 2023 discusses the treatment of acute otitis externa, but it does not address recurrent ear infections or the use of cephalexin 7.
