My wife has labyrinthitis. What can we do to help her symptoms? Please help me help her!

Depends. If due to a virus it is typically self limiting. Dizziness is tough to deal with. Medications given to supress vertigo like meclezine can produce drowsiness and other symptoms. Follow up exam with the doctor is usually advised if the cause is infectious. Sometimes one needs to see an ENT or neurologist with this condition depending on the cause and clinical course.
