Medicine can help with severe nausea and vomiting caused by your vertigo. But using this kind of medicine can also make BPPV take longer to go away. Only you know whether you feel sick enough that it is worth it to take medicine (and possibly have vertigo longer).
Be extra careful so that you don't hurt yourself or someone else if you have a sudden attack of vertigo.
Do not drive or cycle if there is any chance that vertigo could strike and make you lose control. (This depends on what kind of movement triggers vertigo for you.)
At home, keep floors and walkways free of clutter so you don't trip.
Don't use tools or machines that could be dangerous if you suddenly get dizzy or lose your balance.
