Another option for treatment of acute vertigo is a benzodiazepine, such as alprazolam, to suppress active cerebellar responses; this agent may also reduce anxiety associated with an acute episode of vertigo. Benzodiazepines should be started at the lowest dose and increased as needed to the maximum recommended for individual medications based on symptom relief and side effects. Although caution needs to be used when prescribing benzodiazepines, studies show that they can be effective for persons with Meniere's disease.
Other antiemetic medications, such as promethazine or ondansetron, may be needed to treat severe nausea, but these agents should be used cautiously with other medications due a potential side effect of sedation.
