Vestibular Disorders Management

Introduction to Vestibular Suppressant Therapy

Vestibular suppressants, such as benzodiazepines and antihistamines, have pronounced sedative effects, according to the American Academy of Otolaryngology-Head and Neck Surgery 1

The American Academy of Otolaryngology-Head and Neck Surgery recommends betahistine at a standard initial dose of 48 mg daily for maintenance therapy to reduce symptoms or prevent attacks in patients with Meniere's disease, with a moderate strength of evidence 2, 3, 4
Betahistine should be used with caution in patients with asthma or a history of peptic ulcer disease, and avoided in patients with pheochromocytoma, as noted by the American Academy of Otolaryngology-Head and Neck Surgery and the American Academy of Family Physicians 3, 4
The standard initial dose of betahistine is 48 mg daily, divided into three doses of 16 mg, and the dose range is 24-144 mg daily, depending on clinical response, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery and the American Academy of Family Physicians 3

Regular monitoring of vertigo, tinnitus, and hearing loss is recommended to assess treatment efficacy, and it is essential to document symptom changes, tracking resolution, improvement, or worsening of vertigo, tinnitus, and hearing loss, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 2
The American Academy of Otolaryngology-Head and Neck Surgery suggests evaluating treatment efficacy after 2-3 months, and considering gradual reduction or discontinuation of medication once symptoms have stabilized 2, 3

For patients who fail to respond to initial therapy, vestibular rehabilitation/physical therapy may be considered, especially for patients with nonusable hearing, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 2
The American Academy of Otolaryngology-Head and Neck Surgery recommends not to prescribe positive pressure therapy for Meniere's disease 2

The common side effects of betahistine are generally mild and include headache, balance disorders, nausea, nasopharyngitis, sensation of heat, eye irritation, palpitations, and gastrointestinal symptoms, as reported by the American Academy of Otolaryngology-Head and Neck Surgery 4
Betahistine should be taken with food to minimize gastrointestinal side effects, and doses should be spaced evenly throughout the day, as recommended by the American Academy of Family Physicians 3
