Betahistine is belongs to a group of medications used to treat Vertigo associated with Ménière's disease. Vertigo is a condition that causes sufferers to have a sensation of rotation or movement of themselves or their surroundings. Ménière's disease is a disorder of the inner ear that causes vertigo in addition to symptoms such as ringing in the ears, headache, and loss of hearing.

Betahistine is used to reduce the number of episodes of vertigo associated with Ménière's disease. It is believed to work by decreasing the pressure in the ear. This pressure is believed to contribute to the sense of dizziness, nausea, and ringing in the ears and hearing loss that people with Ménière's disease experience.
