Abstract Background Vertigo is a common presenting symptom in clinical practice, predominantly of vestibular etiology, and often medicated with betahistine, despite the lack of knowledge concerning its mechanism of action. This paper’s objective was to review the scientific evidence regarding the efficacy of betahistine on peripheral vertigo. Methods A systematic search of articles written in English, published within the past 10 years, was conducted in April 2024, on online evidence-based medicine databases, using the MeSH terms “betahistine,” “ménière disease,” “acute vestibular neuritis,” “paroxysmal vertigo,” “acute peripheral vestibulopathy,” and “labyrinthitis.” The Strength of Recommendation Taxonomy of the American Academy of Family Physicians was used to evaluate the level of evidence and strength of recommendation. Results This review included 12 articles for evidence analysis. Concerning Menière’s disease, despite contradictory results, three of the articles analyzed showed a positive effect of betahistine, which is in line with the recommendations of the European Academy of Otology and Neurotology and NICE guidelines, while the American Academy of Otorhinolaryngology guidelines suggest offering betahistine as maintenance therapy. For benign paroxysmal positional vertigo, the established treatment is repositioning maneuvers, and three of the five studies analyzed proved the addition of betahistine to be beneficial. In regard to peripheral vertigo from other causes, two out of three articles revealed a positive recommendation for the use of betahistine. Conclusion There is a potential benefit to the utilization of betahistine for various etiologies of peripheral vertigo. However, additional studies are required to establish more robust evidence. |
