A doctor may prescribe anti-sickness medication if you are troubled with being sick (vomiting). Some medicines also help to quieten the nerve messages from the inner ear and may ease vertigo - for example, prochlorperazine . If you need to take medication, only take it for a few days. Taking medication for longer seems to stop the body from recovering from the vertigo as quickly as it would if you don't take the medication. It is also important to get up and about as soon as you can, even if it makes you dizzy. This is for the same reason.
Considering next the otoliths, the situation is slightly better. With respect to measuring the utricle, there are several methods of detecting ocular-counterroll as well as subjective tilting of the visual world (or absence of it). None of these tests have become popular yet, but at least the technology exists. For example, SMI as well as Synapsys sell devices that can measure ocular counter-roll (twisting of the eye with head tilt vs. gravity). Micromedical Technology supplies a commercial device that will measure subjective tilting of the vertical.
