Some cases of vertigo improve over time, without treatment. However, some people have repeated episodes for many months, or even years, such as those with Ménière's disease. There are specific treatments for some causes of vertigo. A series of simple head movements (known as the Epley manoeuvre) is used to treat BPPV. Medicines, such as prochlorperazine and some antihistamines, can help in the early stages or most cases of vertigo. Many people with vertigo also benefit from vestibular rehabilitation training (VRT), which is a series of exercises for people with dizziness and balance problems.
