Is drug consumption correlated with benign paroxysmal positional vertigo (BPPV) recurrence?

Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo and its recurrence is fairly common. Several studies correlated the pathophysiological role of different comorbidities—such as diabetes, osteoporosis, vascular, psychiatric and autoimmune diseases—in the development and recurrence of BPPV. The aim of this study is to analyse the pharmacological history of patients with idiopathic BPPV in relation to the risk of developing recurrence. Data regarding 715 patients aged 12 to 87 years (62.7 ± 14) with non-traumatic BPPV were retrospectively evaluated. These refer to the Vestibular Service, day clinic, and were collected over a 4-year period, between 2014 and 2018. Recurrence of BPPV was observed in 220/715 patients (30.76%).
