Amoxicillin<\/span><\/a> is commonly prescribed for ear infections, especially in children and adults without penicillin allergies. It\u2019s considered the first-line treatment for most uncomplicated ear infections caused by susceptible bacteria. Read on to learn more about amoxicillin and how it\u2019s used for ear infections, including dosage, possible side effects, and alternatives your healthcare provider may consider.<\/span><\/p>\n

Is amoxicillin good for ear infections?<\/span><\/h2>\n

Yes. Amoxicillin is typically the antibiotic of choice for bacterial infections in people who aren\u2019t allergic to penicillin. It works well in children with ear infections because it can penetrate middle ear fluid and is effective against the bacteria that commonly cause ear infections.\u00a0<\/span><\/p>\n

However, antibiotics like amoxicillin won\u2019t treat ear infections that are caused by a virus. Your healthcare provider will take into account factors like your timeline of illness, symptoms, and other in-office investigations to determine whether amoxicillin can help with your symptoms or not.\u00a0<\/span><\/p>\n

An ear infection <\/span>(acute otitis media) is an infection that occurs in the middle ear. The infection may be caused by bacteria or viruses. It is <\/span>most common in young children<\/span><\/a> and often occurs after an upper respiratory tract infection.\u00a0<\/span><\/p>\n

Ear infection causes<\/span><\/h2>\n

Ear infections can be caused by viruses, bacteria, or both. Typically, an ear infection follows an upper respiratory infection (URI). \u201cThat initial URI is typically a cold or virus. This could be caused by any number of viruses, such as influenza, coronavirus, rhinovirus, or adenovirus. The swelling of the nasopharynx from this infection can block the eustachian tube drainage, resulting in the middle ear collecting bacteria,\u201d Dr. Marcellino explains.<\/span><\/p>\n

The most common bacteria that cause ear infections are <\/span>Streptococcus pneumoniae (S. pneumoniae), Haemophilus influenzae (H. influenzae)<\/span><\/i>, and<\/span> Moraxella catarrhalis, <\/span><\/i>according to <\/span>StatPearls<\/span><\/i>.<\/span><\/p>\n
