Many children develop ear infections before the age of two. These infections can be caused by bacteria or viruses and frequently occur after a cold or throat infection. They can cause discomfort and pain. Understanding the available treatments is important for parents of young children and adults who experience frequent ear infections.
Children experience earaches more frequently than adults because their Eustachian tubes are smaller and more horizontal, making it harder for fluid to drain from the middle ear. Their developing immune systems may also make them more susceptible to infections.
You or your child may experience a fever, runny nose, or sore throat in addition to ear pain. These symptoms may indicate an infection, but not every earache is caused by an infection. You may wonder whether antibiotics can help relieve ear pain.
Why Do Ear Infections Occur?
The ear has three main parts: the outer ear, middle ear, and inner ear. The outer ear includes the visible part of the ear and the ear canal, which leads to the eardrum.
The middle ear is an air-filled space containing three tiny bones that transmit sound vibrations from the eardrum toward the inner ear. The inner ear contains fluid-filled structures responsible for hearing and balance.
Ear infections and related conditions can affect different parts of the ear. Common types include:
- Acute otitis media: An infection of the middle ear, often following a cold or another upper respiratory infection.
- Otitis media with effusion: Fluid buildup in the middle ear without the signs of an active acute infection.
- Otitis externa: An infection of the outer ear canal, commonly known as swimmer’s ear.
Ear infections may be caused by viruses or bacteria. Two common bacteria associated with middle ear infections are Streptococcus pneumoniae and Haemophilus influenzae. Viruses that cause the common cold can also contribute to ear infections.
Common signs and symptoms include:
- Ear pain or discomfort
- Fever
- Fussiness or irritability, especially in young children
- Difficulty sleeping
- Rubbing or pulling at the ear
How Are Ear Infections Treated With Antibiotics?
Ear infections are common in young children and often develop after an upper respiratory infection. Before an ear infection occurs, you or your child may experience symptoms such as a cough, runny nose, or sore throat.
Viral respiratory infections can contribute to fluid buildup in the middle ear, creating conditions in which bacteria may multiply and cause a secondary infection. Common bacterial causes include Streptococcus pneumoniae and Haemophilus influenzae.
However, not every ear infection is bacterial. Viral infections can also affect the ear, and antibiotics do not work against viruses. A healthcare professional can determine whether antibiotics are appropriate based on the symptoms and examination findings.
Which Antibiotic Is Best for Ear Infections?
Antibiotics may help treat certain ear infections, but the appropriate treatment depends on the type of infection, its severity, the patient’s age, allergies, and other medical factors.
When antibiotics are prescribed, follow your healthcare professional’s instructions carefully. Take the medication for the prescribed duration, and do not stop early, skip doses, or change the dose without consulting your doctor or pharmacist. If you experience side effects or have concerns about your treatment, seek professional advice.
Antibiotics Used to Treat Ear Infections
A healthcare professional can assess an ear infection by examining the ear and asking about the patient’s symptoms. Some ear infections improve on their own, so antibiotics are not always necessary. For certain mild middle ear infections, a clinician may recommend observation and symptom relief before starting antibiotics.
Seek medical advice if ear pain is severe, persists for more than two or three days, or worsens. Prompt assessment is particularly important if symptoms occur in a very young child or are accompanied by concerning signs such as swelling behind the ear, significant dizziness, or new hearing loss.
Several antibiotics are used to treat bacterial ear infections. Amoxicillin is commonly prescribed for acute middle ear infections when an antibiotic is needed. Other options may be considered depending on previous treatment, allergies, suspected bacteria, and the type of infection.
Antibiotic Ear Drops
Antibiotic ear drops are used for certain bacterial infections of the outer ear and for some infections involving ear tubes. They deliver medication directly to the affected area and may cause fewer systemic side effects than oral antibiotics.
The choice of ear drops depends on the diagnosis and whether the eardrum is intact. Some products are not suitable when the eardrum is perforated or ear tubes are present, so use only drops recommended by a healthcare professional.
Cortisporin: This prescription ear medication contains antibiotics and a corticosteroid to help treat certain bacterial ear canal infections and reduce inflammation. Possible side effects include irritation, stinging, or burning. It may not be suitable for patients with a perforated eardrum.
Ciprodex: This prescription ear drop contains ciprofloxacin, an antibiotic, and dexamethasone, a corticosteroid. It is used for certain outer ear infections and middle ear infections in patients with ear tubes. The prescribed schedule depends on the condition being treated. Possible side effects include ear discomfort, itching, and irritation.
Ofloxacin ear drops: These antibiotic drops may be prescribed for certain outer or middle ear infections, including some cases involving a perforated eardrum or ear tubes. Possible side effects include itching, discomfort, or irritation.
Xtoro: This prescription ear drop contains finafloxacin and is used to treat certain cases of acute otitis externa, commonly known as swimmer’s ear. Possible side effects may include itching, pain, or irritation.
Other prescription ear drops may be recommended for patients with ear tubes or particular types of ear infections. Product names, approved uses, and dosing instructions vary, so check the medication label and consult a healthcare professional before use.
Oral Antibiotics Used to Treat Ear Infections
Amoxil (amoxicillin): Amoxicillin is commonly used to treat bacterial middle ear infections when antibiotics are indicated. Possible side effects include nausea, vomiting, diarrhea, and rash.
Augmentin (amoxicillin/clavulanate): This antibiotic may be prescribed when amoxicillin alone is unlikely to be effective or when certain infections have not improved with initial treatment. Possible side effects include diarrhea, nausea, and stomach discomfort.
Zithromax (azithromycin): Azithromycin may be considered in selected cases, including for some patients with specific antibiotic allergies. It is not the preferred option for every ear infection because resistance patterns can affect its effectiveness. Possible side effects include nausea, diarrhea, and abdominal discomfort.
Keflex (cephalexin): Cephalexin is another oral antibiotic, although it is not a routine first-line treatment for acute middle ear infections. A clinician may consider it in selected circumstances. Possible side effects include stomach discomfort, nausea, vomiting, and diarrhea.
Septra (trimethoprim/sulfamethoxazole): This combination antibiotic has been used for certain bacterial infections, but resistance limits its usefulness for many ear infections. It should be used only when a healthcare professional determines that it is appropriate. Possible side effects include nausea, vomiting, and skin rash. A severe or blistering rash requires urgent medical attention.
Antibiotics can cause side effects and may contribute to antibiotic resistance when used unnecessarily. Never give a child leftover antibiotics or medication prescribed for someone else.
Bottom Line
Antibiotics can help treat some ear infections, but they are not necessary for every case of ear pain. The right treatment depends on the cause of the symptoms and the type of infection.
If your doctor prescribes antibiotics, follow the instructions carefully and take the medication for the prescribed duration. Contact your doctor or pharmacist if you miss a dose, develop side effects, or become unwell while taking the medication.
Not all ear pain is caused by an infection, and antibiotics cannot treat every ear condition. Earwax buildup, tinnitus, and hearing loss may require different types of assessment and care.
