What is the initial management for patients with vestibular neuritis or labyrinthitis?

Initial Management of Vestibular Neuritis and Labyrinthitis

For acute vestibular neuritis or labyrinthitis, use short-term vestibular suppressants (meclizine, benzodiazepines, or antiemetics) for 2-3 days maximum to control severe vertigo and nausea, then discontinue to allow central compensation, while simultaneously initiating vestibular rehabilitation therapy once acute symptoms begin to subside. 1, 2, 3

Acute Symptomatic Management (First 2-3 Days Only)

Vestibular Suppressants - Use Sparingly

• Meclizine (antihistamine) is the most commonly used first-line agent for acute vertigo, working by suppressing the central emetic center 1
• Benzodiazepines may be used cautiously for severe symptoms to alleviate both vertigo and associated anxiety, but carry dependency risk 2
• Prochlorperazine (5-10 mg orally or IV, maximum three doses per 24 hours) can be added for severe nausea/vomiting 1

Critical Timing Consideration

• Vestibular suppressants should be withdrawn after the first several days (preferably within 2-3 days) because prolonged use impedes central vestibular compensation, which is essential for recovery 1, 3
• These medications are for symptom control only, not definitive treatment 1

Specific Drug Therapy Considerations

Corticosteroids - Consider Early

• Oral steroids accelerate recovery of vestibular function when started within 3 days of symptom onset in otherwise healthy individuals with vestibular neuritis 3, 4
• The recovery rate improves to 62% within 12 months with early corticosteroid treatment 4
• Withhold steroids from patients at higher risk of complications 3

What NOT to Use

• Do not routinely prescribe antibiotics for typical viral labyrinthitis, as most cases are self-limited and antibiotics are ineffective against viral pathogens 2
• Do not routinely prescribe antivirals (aciclovir or valacyclovir), as multiple randomized controlled trials have failed to demonstrate benefit 2

Vestibular Rehabilitation Therapy - The Cornerstone

Timing and Implementation

• Begin vestibular rehabilitation as soon as acute symptoms start to subside (typically after 2-3 days), not during the acute vertigo attack 2
• Self-administered or clinician-guided vestibular rehabilitation should be offered for chronic imbalance following the acute phase 2
• Early resumption of normal activity should be encouraged to promote compensation 3
• Home-based therapy is equally effective as clinician-supervised therapy 5

Expected Recovery Timeline

• Most patients experience significant improvement of acute vertigo symptoms within 1-3 weeks 2
• The acute phase is characterized by severe rotational vertigo lasting 12-36 hours with decreasing disequilibrium for the next 4-5 days 2

Lifestyle Modifications

• Limit salt/sodium intake, avoid excessive caffeine, alcohol, and nicotine 1, 5
• Maintain adequate hydration, regular exercise, and sufficient sleep 1, 5
• Manage stress appropriately 1
• Identify and manage potential triggers 2

Follow-Up and Reassessment

• Reassess all patients within 1 month after initial treatment to document resolution or persistence of symptoms 1, 5
• If vertigo symptoms persist beyond 3-4 weeks, further evaluation is warranted to rule out other conditions 2
• Any new or worsening neurological symptoms should prompt immediate medical attention to rule out central causes 2

Critical Safety Warnings

Medication Risks

• Vestibular suppressants cause drowsiness, cognitive deficits, interference with driving, and are a significant independent risk factor for falls, especially in elderly patients 1, 5
• The risk of falls increases with polypharmacy and use of benzodiazepines 6
• Long-term use interferes with central compensation in peripheral vestibular conditions 1

Red Flags - Rule Out Central Causes

• Any patient with significant vascular risk factors should be evaluated for possible brainstem or cerebellar stroke, which could be life-threatening 3
• Definitive central signs are not always present initially 3

Key Distinguishing Features

Labyrinthitis vs. Vestibular Neuritis

• Labyrinthitis presents with sudden severe vertigo PLUS profound hearing loss 2
• Vestibular neuritis presents with vertigo but NO cochlear symptoms 7
• Both present as a single event rather than recurring episodes, distinguishing them from Ménière's disease or BPPV 2
