Vestibular neuritis and labyrinthitis are disorders resulting from an infection that inflames the inner ear or the nerves connecting the inner ear to the brain. This inflammation disrupts the transmission of sensory information from the ear to the brain. Vertigo, dizziness, and difficulties with balance, vision, or hearing may result. Infections of the inner ear are usually viral; less commonly, the cause is bacterial. Such inner ear infections are not the same as middle ear infections, which are the type of bacterial infections common in childhood affecting the area around the eardrum. When other illnesses have been ruled out and the symptoms have been attributed to vestibular neuritis or labyrinthitis, medications are often prescribed to control nausea and to suppress dizziness during the acute phase. Examples include Benadryl (diphenhydramine), Antivert (meclizine), Phenergen (promethazine hydro¬chloride), Ativan (lorazepam), and Valium (diazepam). Other medications that may be prescribed are steroids (e.g., prednisone), an antiviral drug (e.g., Acyclovir), or antibiotics (e.g., amoxicillin) if a middle ear infection is present. If nausea has been severe enough to cause excessive dehydration, intravenous fluids may be given. - See more at: http://vestibular.org/labyrinthitis-and-vestibular-neuritis#sthash.EGbI5TfQ.dpuf
