I realize that this is an old posting, but absolutely valium does help with vertigo. It is one of the very few meds that suppresses the vestibular system. Also, it is the only benzo (i.e., Xanax and other benzos) that does. Doctors are hesitant to prescribe it because of the bad rep it has from the 1960s and 1970s when everyone had Valium in their medicine cabinet. It does take a high dosage to be effective. I have been on 40mg a day for several years, and while my condition is so sever that it doesn't resolve it, it does reduce it enough that it basically saved my life. So you have to ask your doctor for it and not in 2mg or 5mg dosages. Also, it has to be in your system before the vertigo starts for it to be most effective. Take all reliable documentation into your doctor - things from WebMD, NIH, etc., and any case studies you can find to show them that it is effective, recommended, and safe as well as the only benzo with any efficacy.
