The therapeutic effects of bromazepam, a minor benzodiazepine tranquilizer, were evaluated in 32 patients with vertigo or dizziness. The patients were given 2 mg of bromazepam once a day for over 4 weeks. In 21 patients (65.6%), symptons and/or signs were reduced. Mild side effects were noted in 5 patients (15.6%). These results suggest that bromazepam is clinically useful for the treatment of vertigo or dizziness. A questionnaire consisting of 14 questions was used to evaluate handicaps in the patient's everyday life due to dizziness. It appeared that bromazepam reduced these handicaps by improving both mood disturbances and limitations of physical activity due to dizziness.
