Labyrinthitis is irritation and swelling of the inner ear. It can cause vertigo and hearing loss.
Causes
Labyrinthitis is usually caused by a virus and sometimes by bacteria. Having a cold or flu can trigger the condition. Less often, an ear infection may lead to labyrinthitis. Other causes include allergies or certain drugs that are bad for the inner ear.
Your inner ear is important for both hearing and balance. When you have labyrinthitis, the parts of your inner ear become irritated and swollen. This can make you lose your balance and cause hearing loss.
These factors raise your risk for labyrinthitis:

- Sedatives, such as diazepam (Valium)
- Corticosteroids
- Antiviral medicines

- Rest during severe episodes. Slowly resume activity. You may need help walking when you lose your balance during attacks.
- Avoid bright lights, TV, and reading during attacks. Rest during severe episodes, and slowly increase your activity.

Possible Complications
- You can injure yourself or others during attacks of vertigo
- Severe vomiting may cause dehydration
