If the patient’s dizziness is caused by vestibular organ disease or insufficient blood supply to the brain, taking betahistine mesylate can have some effect. Betahistine mesylate can act on the smooth muscle of blood vessels, which can dilate blood vessels, increase cerebral blood flow and improve the symptoms of dizziness. If the patient has peripheral vertigo, such as Meniere’s disease, vestibular neuronitis, or vaginitis, betahistine mesylate can be taken orally to relieve the symptoms of dizziness. If the dizziness is caused by other reasons, such as anemia or hypertension, or heart disease, taking betahistine mesylate will not be effective, and symptomatic treatment is needed according to the cause. For example, patients with high blood pressure should take antihypertensive drugs such as telmisartan and amlodipine besylate to relieve the symptoms.
