Management of Vertigo

Diagnostic and Treatment Approaches

The American Academy of Otolaryngology-Head and Neck Surgery recommends particle repositioning maneuvers as the definitive treatment for Benign Paroxysmal Positional Vertigo (BPPV), with vestibular suppressant medications reserved for short-term symptomatic relief in specific non-BPPV conditions 1, 2, 3
For BPPV, the Epley maneuver is the first-line treatment, with 80-93% success rates after 1-3 treatments, and vestibular suppressant medications should not be used as primary treatment due to lower efficacy (30.8% vs 78.6-93.3% for repositioning maneuvers) 1, 2, 3
The American Academy of Otolaryngology-Head and Neck Surgery suggests that meclizine may only be considered for severe nausea/vomiting during the maneuver itself or in patients who refuse repositioning, and should be used for a maximum of 3-5 days 3

For Ménière's disease, dietary sodium restriction (1500-2300 mg daily) combined with diuretics is recommended as first-line preventive therapy, along with short-term vestibular suppressants (meclizine 25-100 mg daily in divided doses) for acute vertigo attacks, and limitation of alcohol and caffeine intake 4, 5, 3
Betahistine (histamine analogue) may be considered to increase inner ear vasodilation in Ménière's disease 4

Vestibular suppressants, such as meclizine, should be used with caution due to significant adverse effects, particularly in elderly patients, including drowsiness, cognitive deficits, anticholinergic effects, and increased fall risk 3, 6
The American Academy of Otolaryngology-Head and Neck Surgery advises against the use of vestibular suppressants in patients with asthma, glaucoma, or prostate enlargement, and warns of potential drug interactions and driving impairment 3

Vestibular rehabilitation is indicated for persistent dizziness from any vestibular cause, chronic imbalance, or incomplete recovery, and can be self-administered or therapist-directed 3, 6, 1, 2
Patients should be reassessed within 1 month after initial treatment to document resolution or persistence, and counseled on fall risk, potential recurrence, and importance of follow-up 1, 2, 3, 6

Red flags requiring imaging, such as downbeating nystagmus without torsional component, direction-changing nystagmus without head position changes, baseline nystagmus without provocative maneuvers, or lack of response to repositioning maneuvers, should be evaluated with caution, as recommended by the American College of Radiology 7

Atypical Dix-Hallpike results increase the risk of central pathology requiring imaging, and patients with such results should be evaluated further, according to the Journal of the American College of Radiology 7
