Hi Sarah - I posted this on the insights but am posting it here as others may benefit from it.
DD18 gets vertigo. When I had her in the ER they gave her the Antivert as well as Valium. The ER dr was explaining that Valium works directly on the vestibular nerve and is one of the only meds that will do that. Her 2nd major attack we treated with just Valium and she did great after a couple of days.
Also, from the Merck site:

"If a vestibular disorder is present and thought to be secondary to active Meniere's disease or vestibular neuronitis or labyrinthitis, the most effective vestibular nerve suppressants are diazepam Some Trade Names VALIUM (2 to 5 mg po q 6 to 8 h, with higher doses given under supervision for severe vertigo) or oral antihistamine/anticholinergic drugs (eg, meclizine Some Trade Names ANTIVERT BONINE Click for Drug Monograph 25 to 50 mg po tid)."
