Medication for Dizziness
For acute vertigo attacks, use a limited course of vestibular suppressants (antihistamines, benzodiazepines, or anticholinergics) for symptomatic relief only during the attack itself—not for routine or prolonged use—and prioritize identifying the underlying cause to guide definitive treatment. 1
Acute Symptomatic Management
The approach to medication depends critically on whether you're treating acute symptoms versus preventing recurrence, and the underlying etiology:
For Acute Vertigo Episodes
Vestibular suppressants should be used only for short-term symptom control (maximum 3 days) during acute attacks 1, 2. Options include:
- Antihistamines (e.g., dimenhydrinate, meclizine) - first-line for acute symptom control 3, 4
- Benzodiazepines (e.g., diazepam, lorazepam) - effective but carry significant risk for dependence and falls, especially in elderly patients 1, 2
- Anticholinergics (e.g., scopolamine transdermal) - can suppress acute attacks but cause blurred vision, dry mouth, urinary retention, and sedation 1
Critical caveat: All vestibular suppressants increase fall risk, cause cognitive deficits, and interfere with central compensation mechanisms. They should never be used routinely or long-term 2.
For Antiemetic Control
Antiemetics are appropriate for managing nausea/vomiting associated with acute vertigo:
- Ondansetron (IV) - superior for nausea control with fewer side effects 5
- Promethazine (IM) - more effective for vertigo itself but causes more sedation and side effects 5
Cause-Specific Treatment
Benign Paroxysmal Positional Vertigo (BPPV)
Do NOT use medications for BPPV - they are ineffective and potentially harmful 2. The Epley maneuver and other canalith repositioning procedures have 78.6-93.3% improvement rates versus only 30.8% with medication alone 2.
The only exception: short-term antiemetics for severe nausea during repositioning maneuvers in patients who previously experienced severe symptoms 2.
Ménière's Disease
For acute attacks: Limited course of vestibular suppressants as above 1
For prophylaxis:
- Betahistine (higher doses than traditional 16mg TID; consider 48mg TID or higher) - increases cochlear blood flow 3, 6
- Diuretics - first-line oral prophylactic option 3, 7
- Dietary sodium restriction - essential adjunct 1
For refractory cases: intratympanic steroids or gentamicin 3
Vestibular Neuritis
Acute phase: Vestibular suppressants for symptom relief (maximum 3 days) 7
Recovery phase: Vestibular rehabilitation therapy is essential; prolonged medication use delays central compensation 7
Corticosteroids: May improve peripheral vestibular function recovery, though evidence is insufficient for universal recommendation 6
Vestibular Migraine
Prophylactic treatment (analogous to migraine without aura):
- Beta-blockers (e.g., metoprolol) 6, 4
- Calcium channel blockers (e.g., flunarizine) - one RCT supports use 6
- Topiramate 6, 4
- Tricyclic antidepressants 3
Central Causes (Cerebellar Disorders, Downbeat Nystagmus)
4-aminopyridine - evidence-based treatment for downbeat nystagmus and episodic ataxia type 2 (two RCTs) 6, 4
Common Pitfalls to Avoid
Never prescribe vestibular suppressants beyond 3 days - they delay central compensation and increase fall risk 2, 8
Don't use medications as primary treatment for BPPV - repositioning maneuvers are vastly superior 2
Beware polypharmacy in elderly patients - vestibular suppressants are independent risk factors for falls, and risk compounds with multiple medications 2
Insufficient evidence exists to favor one vestibular suppressant class over another for acute symptom control 1
Reassess within 1 month - patients with persistent symptoms remain at high fall risk and require alternative management 2
