How Does This Medication Work? What Will It Do for You?
Betahistine belongs to a group of medications used to treat vertigo associated with Ménière’s disease. Vertigo is a condition that causes sufferers to feel like their surroundings are moving or spinning. Ménière’s disease is a disorder of the inner ear that causes vertigo in addition to other symptoms such as ringing in the ears, headache, and hearing loss.
Betahistine is prescribed to reduce the number of vertigo episodes associated with Ménière’s disease. It’s believed to work by decreasing the pressure in the ear, which causes the dizziness, nausea, ringing, and hearing loss that people with Ménière’s disease experience.
