Recommended Glucocorticoid Dosing for Vestibular Neuritis
For vestibular neuritis, oral prednisolone at 50 mg/day for 5 days followed by a 5-day taper is recommended as the optimal glucocorticoid regimen, ideally started within 24 hours of symptom onset for best outcomes. 1, 2
Dosing Protocol
Initial Treatment:
- First-line therapy: Oral prednisolone 50 mg/day for 5 days
- Tapering schedule: Gradually reduce dose over the next 5 days (total 10-day course)
- For patients with severe nausea: Consider initial intravenous betamethasone 8 mg for 1-2 days, then transition to oral prednisolone 2
Timing Considerations:
- Treatment should be initiated as soon as possible after symptom onset
- Patients treated within 24 hours show significantly better vestibular recovery (100% normal caloric test results) compared to those treated between 25-72 hours (58% normal results) 1
- Treatment within 3 days of symptom onset still provides benefit compared to no treatment 2
Evidence for Efficacy
The recommended dosing is supported by multiple studies showing:
- Improved long-term recovery of vestibular function (70% vs 34% normal caloric test results at follow-up) 2
- Reduced hospital stay (1.8 vs 3.0 days) 2
- Better vestibular restitution when started earlier 1
A meta-analysis of 15 trials with 852 participants found:
- Odds ratio of 3.1 for good outcome in acute phase with steroid treatment
- Odds ratio of 2.4 for restoration of vestibular function in follow-up 3
Clinical Considerations
Patient Monitoring:
- Assess improvement in vertigo symptoms and nystagmus
- Consider follow-up vestibular testing (caloric tests) at 3 months to evaluate recovery
- Monitor for common glucocorticoid side effects including:
- Hyperglycemia
- Hypertension
- Sleep disturbances
- Mood changes
Potential Pitfalls:
- Delayed treatment: Starting treatment after 24 hours results in significantly lower rates of complete vestibular recovery 1
- Inadequate dosing: Using lower doses than recommended may reduce efficacy
- Abrupt discontinuation: Always taper glucocorticoids to prevent adrenal insufficiency
- Overreliance on medication alone: Consider adding vestibular rehabilitation exercises for comprehensive management 4
Long-term Outcomes
While glucocorticoids appear to accelerate recovery in the short term, some studies suggest they may not significantly alter long-term outcomes compared to vestibular rehabilitation alone 4, 5. However, the faster symptomatic relief and reduced hospital stay provide meaningful benefits for quality of life and healthcare utilization.
For optimal outcomes, the evidence strongly supports early intervention with the recommended glucocorticoid regimen, particularly within the first 24 hours of symptom onset.
