Betahistine is used for Meniere’s disease. It helps to reduce the episodes of vertigo associated with Meniere’s disease.
How Betahistine works
Betahistine is a histamine analog. It works by improving the blood flow in the inner ear which reduces the pressure of excess fluid there. Excess fluid can send signals to the brain causing nausea, dizziness or spinning sensations (symptoms of Ménière’s disease).
Betahistine is indicated for treatment of Ménière’s syndrome, symptoms of which may include vertigo, tinnitus, hearing loss and nausea.
Betahistine is contraindicated in patients with phaeochromocytoma. As betahistine is a synthetic analogue of histamine it may induce the release of catecholamines from the tumor resulting in severe hypertension.
