Amoxicillin 500 mg cost

Children with persistent symptoms despite 48 to 72 hours of antibiotic therapy should be reexamined, and a second-line agent, such as amoxicillin/clavulanate, should be used if appropriate.

Otitis media with effusion is defined as middle ear effusion in the absence of acute symptoms.

Antibiotics, decongestants, or nasal steroids do not hasten the clearance of middle ear fluid and are not recommended.

Children with evidence of anatomic damage, hearing loss, or language delay should be referred to an otolaryngologist. Otitis media is among the most common issues faced by physicians caring for children.

Approximately 80% of children will have at least one episode of acute otitis media (AOM), and between 80% and 90% will have at least one episode of otitis media with effusion (OME) before school age.1 , 2 This review of diagnosis and treatment of otitis media is based, in part, on the University of Michigan Health System's clinical care guideline for otitis media.2.

An AOM diagnosis requires moderate to severe bulging of the tympanic membrane, new onset of otorrhea not caused by otitis externa, or mild bulging of the tympanic membrane associated with recent onset of ear pain (less than 48 hours) or erythema. Middle ear effusion can be detected with the combined use of otoscopy, pneumatic otoscopy, and tympanometry.

Adequate analgesia is recommended for all children with AOM. Deferring antibiotic therapy for lower-risk children with AOM should be considered. High-dose amoxicillin (80 to 90 mg per kg per day in two divided doses) is the first choice for initial antibiotic therapy in children with AOM. Children with middle ear effusion and anatomic damage or evidence of hearing loss or language delay should be referred to an otolaryngologist. A = consistent, good-quality patient-oriented evidence; B = inconsistent or limited-quality patient-oriented evidence; C = consensus, disease-oriented evidence, usual practice, expert opinion, or case series.

Abstract Etiology and Risk Factors Diagnosis Management of Acute Otitis Media Management of OME Tympanostomy Tube Placement Special Populations References. Previous diagnostic criteria for AOM were based on symptomatology without otoscopic findings of inflammation. The updated American Academy of Pediatrics guideline endorses more stringent otoscopic criteria for diagnosis.8 An AOM diagnosis requires moderate to severe bulging of the tympanic membrane ( Figure 1 ) , new onset of otorrhea not caused by otitis externa, or mild bulging of the tympanic membrane associated with recent onset of ear pain (less than 48 hours) or erythema. AOM should not be diagnosed in children who do not have objective evidence of middle ear effusion.8 An inaccurate diagnosis can lead to unnecessary treatment with antibiotics and contribute to the development of antibiotic resistance. Erythema and bulging of the tympanic membrane with loss of normal landmarks are noted.

Erythema and bulging of the tympanic membrane with loss of normal landmarks are noted.

OME is defined as middle ear effusion in the absence of acute symptoms.10 , 11 If OME is suspected and the presence of effusion on otoscopy is not evident by loss of landmarks, pneumatic otoscopy, tympanometry, or both should be used.11 Pneumatic otoscopy is a useful technique for the diagnosis of AOM and OME8 – 12 and is 70% to 90% sensitive and specific for determining the presence of middle ear effusion.

By comparison, simple otoscopy is 60% to 70% accurate.10 , 11 Inflammation with bulging of the tympanic membrane on otoscopy is highly predictive of AOM.7 , 8 , 12 Pneumatic otoscopy is most helpful when cerumen is removed from the external auditory canal.

Tympanometry and acoustic reflectometry are valuable adjuncts to otoscopy or pneumatic otoscopy.8 , 10 , 11 Tympanometry has a sensitivity and specificity of 70% to 90% for the detection of middle ear fluid, but is dependent on patient cooperation.13 Combined with normal otoscopy findings, a normal tympanometry result may be helpful to predict absence of middle ear effusion.

Acoustic reflectometry has lower sensitivity and specificity in detecting middle ear effusion and must be correlated with the clinical examination.14 Tympanocentesis is the preferred method for detecting the presence of middle ear effusion and documenting bacterial etiology,8 but is rarely performed in the primary care setting.

Antibiotic-resistant bacteria remain a major public health challenge.

A widely endorsed strategy for improving the management of AOM involves deferring antibiotic therapy in patients least likely to benefit from antibiotics.18 Antibiotics should be routinely prescribed for children with AOM who are six months or older with severe signs or symptoms (i.e., moderate or severe otalgia, otalgia for at least 48 hours, or temperature of 102.2°F [39°C] or higher), and for children younger than two years with bilateral AOM regardless of additional signs or symptoms.8. Among children with mild symptoms, observation may be an option in those six to 23 months of age with unilateral AOM, or in those two years or older with bilateral or unilateral AOM.8 , 10 , 19 A large prospective study of this strategy found that two out of three children will recover without antibiotics.20 Recently, the American Academy of Family Physicians recommended not prescribing antibiotics for otitis media in children two to 12 years of age with nonsevere symptoms if observation is a reasonable option.21 , 22 If observation is chosen, a mechanism must be in place to ensure appropriate treatment if symptoms persist for more than 48 to 72 hours.

Strategies include a scheduled follow-up visit or providing patients with a backup antibiotic prescription to be filled only if symptoms persist.8 , 20 , 23. [ corrected] Table 3 summarizes the antibiotic options for children with AOM.8 High-dose amoxicillin should be the initial treatment in the absence of a known allergy.8 , 10 , 24 The advantages of amoxicillin include low cost, acceptable taste, safety, effectiveness, and a narrow microbiologic spectrum. Children who have taken amoxicillin in the past 30 days, who have conjunctivitis, or who need coverage for ?-lactamase–positive organisms should be treated with high-dose amoxicillin/clavulanate (Augmentin).8.

The diagnosis and management of acute otitis media .

Oral cephalosporins, such as cefuroxime (Ceftin), may be used in children who are allergic to penicillin. Recent research indicates that the degree of cross reactivity between penicillin and second- and third-generation cephalosporins is low (less than 10% to 15%), and avoidance is no longer recommended.25 Because of their broad-spectrum coverage, third-generation cephalosporins in particular may have an increased risk of selection of resistant bacteria in the community.26 High-dose azithromycin (Zithromax; 30 mg per kg, single dose) appears to be more effective than the commonly used five-day course, and has a similar cure rate as high-dose amoxicillin 300 mg amoxicillin/clavulanate.8 , 27 , 28 However, excessive use of azithromycin is associated with increased resistance, and routine use is not recommended.8 Trimethoprim/sulfamethoxazole is no longer effective for the treatment of AOM due to evidence of S.

Intramuscular or intravenous ceftriaxone (Rocephin) should be reserved for episodes of treatment failure or when a serious comorbid bacterial infection is suspected.2 One dose of ceftriaxone may be used in children who cannot tolerate oral antibiotics because it has been shown to have similar effectiveness as high-dose amoxicillin.30 , 31 A three-day course of ceftriaxone is superior to a one-day course in the treatment of nonresponsive AOM caused by penicillin-resistant S.

pneumoniae .31 Although some children will likely benefit from intramuscular ceftriaxone, overuse of this agent may significantly increase high-level penicillin resistance in the community.2 High-level penicillin-resistant pneumococci are also resistant to first- and third-generation cephalosporins. Antibiotic therapy for AOM is often associated with diarrhea.8 , 10 , 32 Probiotics and yogurts containing active cultures reduce the incidence of diarrhea and should be suggested for children receiving antibiotics for AOM.32 There is no compelling evidence to support the use of complementary and alternative treatments in AOM.8.
