Medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: October 2026
Quick Answer: What is an inner ear infection?
An inner ear infection is inflammation of parts of the inner ear, such as the labyrinth or vestibular nerve, that can affect hearing and balance. It typically causes vertigo, dizziness, nausea and balance problems. Treatment manages symptoms with steroids, antihistamines or anti-nausea medicines and treats the cause when needed. Most infections go away within one to two weeks. [1]
What the research says
Most treatment research focuses on vestibular neuritis, one of the two main types of inner ear infection.
Steroids may speed some recovery measures, but the evidence is limited. A Cochrane review of 4 small trials (149 participants) found that people given oral corticosteroids were more likely to have complete recovery on a balance-function (caloric) test at 1 month (risk ratio 2.81), but there was no significant difference at 12 months. The authors judged the evidence insufficient to support steroids for acute vestibular neuritis (Fishman et al., Cochrane Database of Systematic Reviews, 2011 [2]).
A newer placebo-controlled trial found no added benefit from steroids. Among 69 adults with acute vestibular neuritis randomly assigned to placebo, 3-day steroids, or 10-day steroids, all groups improved over 12 months with no significant differences between groups, and the steroids were well tolerated (Sjögren et al., Journal of Vestibular Research, 2025 [3]).
Balance exercises may help early on. A meta-analysis of 4 trials (182 patients) found steroids improved an objective balance-function measure earlier, while vestibular rehabilitation therapy improved dizziness handicap scores earlier. There were no differences at 12 months, and the authors suggested offering rehabilitation first, with steroids added when appropriate (Hidayati et al., Medicina, 2022 [4]).

What Is an Inner Ear Infection?
An inner ear infection, medically known as otitis interna, causes parts of the inner ear to become irritated or inflamed. As a result, hearing and balance can be affected. The term can refer to any condition that causes inflammation in the inner ear. Colds and flu can cause it, or it can develop when an infection in the middle ear spreads to the inner ear. Many people with inner ear infections have problems with hearing and balance [1].
Who Can Develop One?
Inner ear infections can occur at any age, but they are most common in adults aged 30 to 60. Children can also develop an inner ear infection as a symptom of bacterial meningitis [1].
Types of Inner Ear Infections
There are two primary types:
Labyrinthitis: An infection of the labyrinth, the part of the inner ear that controls hearing and balance. It is most commonly caused by viral infections. [1]
Vestibular Neuritis: An infection of the vestibular nerve, the part of the inner ear that controls balance and eye movement. It often develops before or alongside a viral infection. [1]
Is an Inner Ear Infection Contagious?
An inner ear infection is not contagious on its own, but the viruses or bacteria that cause these infections can spread from person to person [1].
Symptoms and Warning Signs
Because the inner ear controls hearing and balance, people with an inner ear infection may have a wide range of symptoms linked to those senses. These can include [1]:
Balance problems.
Vertigo.
Dizziness.
Hearing issues.
Nausea and vomiting.
A feeling of fullness in the ear.
Ringing in the ear (tinnitus).
Headaches.
Earaches.
Fluid draining from the ear.
Sometimes an infection spreads to the inner ear from another area of the body, such as the airway. In these cases you may also have a runny nose or a fever. Often the first symptoms begin fading when the inner ear symptoms begin [1].
Causes and Risk Factors
Most inner ear infections are caused by a virus, such as influenza, herpes zoster oticus, or Epstein-Barr. Less commonly, they are the result of bacteria [1].
Cause Type | Description |
|---|---|
Viral infections | The most common cause, including influenza, herpes zoster oticus, and Epstein-Barr virus. |
Bacterial infections | Less common. An infection in the middle ear can spread to the inner ear. |
Bacterial meningitis | Children can develop an inner ear infection as a symptom of bacterial meningitis. |
What Happens If It Goes Untreated?
Left untreated, an inner ear infection can damage the vestibular system, which controls balance, and recovery may last longer. An unchecked infection could also lead to permanent partial or total hearing loss, so it is important to see a healthcare provider at the first sign of problems [1].
Ways to Lower Your Risk
You cannot prevent inner ear infections altogether, but these steps can reduce your risk [1]:
Wash your hands frequently.
Do not smoke.
Manage your allergies.
Avoid people who have colds or other upper respiratory illnesses.
Make sure your vaccinations are up to date.
Diagnosis and Clinical Testing
A healthcare provider will perform a balance examination and possibly a neurological assessment. Unlike other types of ear infections, inner ear infections cannot be properly diagnosed with a visual examination. A comprehensive assessment is needed to rule out other conditions that share similar symptoms, such as stroke, migraine headaches, or Meniere's disease [1].
Management and Treatment Options
Sometimes a provider may prescribe antivirals or antibiotics to treat an inner ear infection. More often, they focus on treating your symptoms rather than the infection itself [1].
Medical Interventions
Steroids: Often prescribed to ease inflammation. [1]
Antivirals or Antibiotics: Sometimes prescribed to treat the infection. [1]
Antihistamines: For vertigo or dizziness, a provider may recommend antihistamines such as diphenhydramine, fexofenadine, or loratadine. [1]
Anti-Nausea Medicines: For nausea and vomiting, a provider may prescribe an antiemetic such as prochlorperazine or a vestibular suppressant such as meclizine. [1]
Symptom Relief and Home Care
Follow your healthcare provider's recommendations and take all medications as prescribed. Over-the-counter pain relievers such as acetaminophen and ibuprofen can ease symptoms. Some research studies also suggest that ginger tea can ease vertigo and nausea [1].
Recovery and Outlook
Inner ear infections can last longer than other types of ear infections. When treated right away, most go away in one to two weeks. It is generally safe to return to work, school, and other routine activities once your healthcare provider has treated you [1].
When to See a Healthcare Provider
Schedule a visit if your symptoms do not improve within three days or if you develop a fever of 100.4°F (38°C) or higher [1].
Conclusion
Inner ear infections can cause worrying symptoms such as vertigo, dizziness, and balance problems. Most go away within two weeks with proper treatment, and a healthcare provider can confirm the diagnosis, choose a treatment plan, and recommend ways to manage your symptoms. If you notice problems with your balance or hearing, see a healthcare provider at the first sign.
Frequently Asked Questions
What is an inner ear infection?
The term can refer to any condition that causes inflammation in the inner ear. Colds and flu can cause it, or it can develop when an infection in the middle ear spreads to the inner ear. The medical term is otitis interna.
What are the two main types of inner ear infection?
Labyrinthitis, an infection of the labyrinth that controls hearing and balance, and vestibular neuritis, an infection of the vestibular nerve that controls balance and eye movement.
What is the difference between a middle ear infection and an inner ear infection?
A middle ear infection can usually be seen on a visual exam of the ear. An inner ear infection cannot be properly diagnosed that way and needs a balance exam and possibly a neurological assessment. An infection in the middle ear can also spread to the inner ear.
Can a cold lead to an inner ear infection?
Yes. Colds and the flu can cause inflammation in the inner ear.
