Are ear drops better than oral antibiotics?
The latest study, involving 80 children, showed that antibiotic ear drops performed better and faster in treating middle ear infections in children with ear tubes than merely taking oral antibiotics such as swallowing a pill or liquid. The findings are available online in the journal Pediatrics.
What is the best oral antibiotic for ear infection?
If your doctor recommends antibiotics to treat a severe ear infection, they will likely recommend an oral treatment, such as amoxicillin (Amoxil).
When do you need oral antibiotics for ear infection?
Antibiotics are sometimes not needed for middle ear infections. However, severe middle ear infections or infections that last longer than 2–3 days need antibiotics right away. For mild middle ear infection, your doctor might recommend watchful waiting or delayed antibiotic prescribing.
Why do doctors prescribe Cipro and Flagyl together?
Ciprofloxacin works by preventing the bacterial cells from dividing and repairing, thereby killing the bacteria. Metronidazole kills parasites and anaerobic bacteria that cause infections by damaging their DNA. Together, they treat your infection effectively.

How can you tell the difference between otitis media and otitis externa?
Otitis externa is easily diagnosed by looking into the external ear with an otoscope. The main problem with diagnosis is deciding whether or not there is also an otitis media, as often one cannot see the ear drum very well as the external ear canal is swollen, painful and filled with debris.
Can you take amoxicillin for swimmers ear?
Oral antibiotics are rarely used for swimmer's ear. An over-the-counter pain medicine, such as ibuprofen (Advil®, Motrin®) can be taken to relieve pain and swelling. Corticosteroids may be prescribed to reduce itching and inflammation.
Can you have otitis media and externa at the same time?
In severe cases of otitis externa, oral (or even intravenous) antibiotics are also used, especially if the infection spreads to the outer parts of the ear. Although otitis media and otitis externa can both be present at the same time, they generally have nothing to do with each other.
What antibiotics are used for otitis externa?
The frequent use of Amoxicillin and Co-amoxiclav (amoxicillin/clavulanic acid) identified in our review was concerning as the causative bacteria in AOE are predominantly Pseudomonas aeruginosa and Staphylococcus aureus [8], and these antibiotics are inactive against these pathogens. Ciprofloxacin and Flucloxacillin are better choices when indicated. A UK study of general practice electronic healthcare records of 72,278 patients with a diagnosis of otitis externa between 2010 and 2015 found that the rate of inappropriate choice of oral antibiotics was high at 67% [19]. They also found that the most commonly prescribed inappropriate antibiotic was Amoxicillin [19]. The findings of this study and our results indicate that the inappropriate selection of oral antibiotics in AOE appears to be a highly prevalent problem in primary care in the United Kingdom. Not only ineffective, this practice may also lead to avoidable adverse drug events, non-compliance, antibiotic resistance, and the associated healthcare costs [5,8]. Topical antibiotics do not typically suffer with these problems [8]. The high local concentration of topical antibiotics far exceeds the minimum inhibitory concentrations needed to eradicate even resistant organisms [8]. This may explain the equivalent efficacy of various topical preparations demonstrated in meta-analyses [4,5].
How many patients are prescribed antibiotics in ENT?
Of the hospital-based studies, Pabla et al. [13] found that GPs prescribed oral antibiotics in 16% of patients that had attended their ENT emergency clinic. Trinidade et al. [14] showed a similar rate of 17%, often with Co-amoxiclav (amoxicillin/clavulanic acid), followed by Amoxicillin and Erythromycin.
What is the prevalence of oral antibiotics?
Oral antibiotics: The prevalence of prescriptions for oral antibiotics as monotherapy was 6%-30% in patients treated in primary care . A narrower primary care prescription rate of 16%-17% was observed in patients attending the ENT emergency clinic. When oral antibiotics were prescribed, Amoxicillin and Co-amoxiclav (amoxicillin/clavulanic acid) were consistently chosen by GPs to treat otitis externa. The use of oral antibiotics as monotherapy may be an estimate of the rate of cases of otitis externa that were suboptimally managed as the inferred omission of topical antibiotics highlights a potential unawareness among prescribers that topical therapy is the mainstay of treatment. The Thailand study by Greer et al. [16] found an oral antibiotic prescription rate of 80%; however, this was considered an outlier as described below. Trinidade et al. [14] suggested that the rate of unnecessary oral antibiotics, which were defined as lacking a valid indication, may be as high as 86% according to their dataset. However, this finding should be treated with caution, also discussed below.
What are the primary outcomes of antibiotics?
The primary outcome measures were the rates of topical, oral, or a combination of antibiotic prescriptions for uncomplicated acute otitis externa (AOE) in primary care . The secondary outcome measures included the choice of prescribed antibiotics and the rate of oral antibiotic prescriptions without a valid indication.
What is the most common antibiotic prescribed?
The most frequent prescriptions were Amoxicillin or Ampicillin (34%), followed by Co-amoxiclav (amoxicillin/clavulanic acid) (19%), Flucloxacillin (15%), and macrolides (14%) [1]. Selwyn and Lau [11] found that 6% of patients were given only an oral antibiotic, usually Amoxicillin (11%).
What is the rate of combination therapy with topical and oral antibiotics?
Rowlands et al. [1] found that the rate of combination therapy with topical and oral antibiotics was 15% . Selwyn and Lau [11] identified a similar rate of 16%. Pabla et al. [13] and Trinidade et al. [14] found that the rate was higher at 28% and 33%, respectively.
How high is the rate of unnecessary antibiotics?
Trinidade et al. [14] had provided some data to indicate that the rate of unnecessary oral antibiotic prescriptions was as high as 86%. However, the group had only used the diagnosis of perichondritis as an indication for oral antibiotics. The number of patients with an immunocompromised status or systemic upset were not accounted for, and therefore we cannot reliably deduce the rate of unnecessary oral antibiotic prescriptions. No other study had evaluated the validity of the oral antibiotic prescriptions.

The rate of topical antibiotic prescriptions was between 77% and 95%, and oral antibiotics varied between 6% and 30% in patients that were managed only in primary care. Patients that were referred to an ENT emergency clinic had initially been treated by primary care practitioners with topical antibiotics in 14%-60% of cases and oral antibiotics in 16%-17%. The most commonly prescribed oral antibiotics were Amoxicillin and Co-amoxiclav (amoxicillin/clavulanic acid). No study had comprehensively reviewed the indication for oral antibiotics.
Is antibiotic over prescribed for AOE?
Background: There is a perception among ear, nose, and throat (ENT) surgeons that oral antibiotics are over-prescribed for acute otitis externa (AOE), and the potential for topical therapy as first-line treatment is not fully realized in primary care. We evaluated the prescription rate of topical and oral antibiotics for AOE in primary care and in patients referred to the ENT emergency clinic.
Does antibiotic cover AOE?
Although the rate of oral antibiotic prescriptions was relatively low, the choice of antibiotic for empirical treatment frequently did not cover the typical bacteria in AOE. There is a need for improvement in primary care prescribing of topical therapy prior to referral to the ENT emergency clinic. Keywords: acute otitis externa; antibiotic ...
What is the treatment for otitis externa?
This team may include the primary clinician, nurses, and pharmacists. Current treatment guidelines recommend topical antibiotics with steroids and pain medications as first-line treatment. Providers have frequently prescribed oral antibiotics despite evidence-based data that recommends their avoidance.[2] The selection of ideal treatment should rely on history, physical examination, risk factors, and clinical presentation to avoid antibiotic resistance or unfavorable outcomes. However, when the diagnosis is not clear, or when the patient is not improving despite appropriate management, prompt consultation with otorhinolaryngology is recommended.
What is otitis externa?
Otitis externa (OE) is an inflammation, that can be either infectious or non-infectious, of the external auditory canal. In some cases, inflammation can extend to the outer ear, such as the pinna or tragus. OE can be classified as acute (lasts less than 6 weeks) or chronic (lasts more than 3 months). It is also known as swimmer's ear as it often occurs during the summer and in tropical climates and having retained water in the ears increases the risk for it. The most common cause of acute otitis externa is a bacterial infection. It may be associated with allergies, eczema, and psoriasis.
What is the most common complication of otitis externa?
AOE can progress to chronic otitis externa, and it can cause canal stenosis and hearing loss.[6] The most common complications of otitis externa are malignant otitis externa and periauricular cellulitis. Other complications include:[6]
What is the physical examination for otitis externa?
Otitis externa is a clinical diagnosis; therefore, a complete history and physical examination are required. Physical examination should include evaluation of the auricle, assessment of surrounding skin and lymph nodes, and pneumatic otoscopy. Otoscopy will reveal an erythematous and edematous ear canal with associated debris (yellow, white, or gray). In some cases, the tympanic membrane is erythematous or partially visualized due to edema of the external auditory canal. Concomitant otitis media is suspected when there is evidence of an air-fluid level along the tympanic membrane (middle ear effusion).
How common is otitis externa?
Otitis externa is a common condition and can occur in all age groups. It is uncommon in patients younger than 2 years old. [2][3] Its incidence is unknown, but it peaks around the age of 7-14. Approximately 10% of people will develop otitis externa during their lifetime, and the majority of cases (95%) are acute. There is no gender predominance. The majority of cases occur during the summer and in tropical climates; it is possibly related to increased humidity. [1]
What is the external auditory canal?
The external auditory canal is covered by hair follicles and cerumen-producing glands. Cerumen provides a protective barrier and an acidic environment that inhibits bacterial and fungal growth.[4] The inflammatory response in otitis externa is believed to be caused by a disruption of the normal pH and protective factors within the auditory canal. [5][6] This includes a sequential process of damage to the epithelium, loss of protective wax, and accumulation of moisture that leads to a higher pH and bacterial growth. [7]
Is otitis externa a fungal infection?
Pseudomonas aeruginosaand Staphylococcus aureusare the most common pathogens involved in otitis externa. Otitis externa can also occur as a polymicrobial infection , and rarely, it may result from a fungal infection such as Candidaor Aspergillus .
