Thanks for writing in.
There are 2 measures which can help prevent vertigo
in this situation. Avoid bending down to pick up things and avoid extending your neck as such. also stay away from the speakers. I am afraid that there is no drugs as such which can effectively prevent a vertigo attack. Drugs like cinnarazine can only help abort an attack. Only if the vertigo is due to conditions like Meniere's disease, drugs like betahistine
are useful in preventing attacks.
Hope this helps.
