Can Klonopin (Clonazepam) Be Used to Treat Vertigo?

Clonazepam can be used for short-term symptomatic management of severe vertigo, but should not be used as primary or definitive treatment, and must be limited to 3-5 days to avoid interfering with vestibular compensation and increasing fall risk.

Evidence-Based Recommendations

When Benzodiazepines Like Clonazepam May Be Appropriate

• The American Academy of Otolaryngology-Head and Neck Surgery recommends offering a limited course of benzodiazepines for short-term symptom control during severe acute vestibular attacks, typically for no more than 3-5 days. 1

• Benzodiazepines may help with the psychological anxiety component that often accompanies vertigo, which can be a significant contributor to disability. 1

• For patients with Ménière's disease, benzodiazepines should only be offered during acute attacks, not as continuous therapy. 1, 2

Critical Limitations and Warnings

• The American Academy of Otolaryngology-Head and Neck Surgery explicitly recommends against routine treatment of BPPV (the most common cause of vertigo) with benzodiazepines or other vestibular suppressants. 3

• Vestibular suppressants should be withdrawn as soon as possible, preferably after the first several days, because prolonged use interferes with central vestibular compensation—the brain's natural healing process. 1, 4

• Benzodiazepines are explicitly contraindicated during vestibular rehabilitation therapy, as they impede the compensation process that is essential for long-term recovery. 1

Significant Safety Concerns

• Benzodiazepines are a significant independent risk factor for falls, especially in elderly patients, who already have heightened fall risk from vertigo itself. 1, 4

• Side effects include drowsiness, cognitive deficits that interfere with driving or operating machinery, and potential for dependence with prolonged use. 1

• In elderly patients with polypharmacy, drug-drug interactions with cardiovascular and other medications are a major concern. 1

Clinical Algorithm for Decision-Making

Step 1: Determine the type of vertigo

• If BPPV (brief episodes triggered by head position changes): Do NOT use clonazepam—perform canalith repositioning maneuvers instead, which have 80% success rates. 2
• If vestibular neuritis or Ménière's disease with severe acute symptoms: Consider short-term benzodiazepine use. 1, 2

Step 2: Assess severity and timing

• Only prescribe for severe, disabling symptoms that prevent the patient from functioning. 3
• Limit duration to 3-5 days maximum. 1
• Consider as prophylaxis only for patients who have previously experienced severe nausea during repositioning procedures. 3

Step 3: Evaluate patient-specific risk factors

• Elderly patients: Higher fall risk and anticholinergic burden—use extreme caution. 1, 4
• Patients on multiple medications: Review for drug-drug interactions. 1
• Patients refusing other treatments: May be considered as temporary bridge to definitive therapy. 3

Step 4: Plan transition to definitive treatment

• Begin vestibular rehabilitation exercises as soon as acute symptoms subside, usually within the first week. 1
• Discontinue benzodiazepines before starting vestibular rehabilitation. 1
• Reassess within 1 month to document symptom resolution or persistence. 1, 2

Supporting Research Evidence

• A 25-year retrospective survey found that clonazepam 0.5-1.0 mg daily achieved complete or substantial control of vertigo in 77.4% of patients, though this study had methodological limitations and did not address the critical issue of delayed vestibular compensation. 5

• Benzodiazepines work by decreasing internuclear inhibition in the vestibular system, but this same mechanism delays the brain's natural compensation process. 6, 7

Common Pitfalls to Avoid

• Do not prescribe benzodiazepines as first-line treatment without determining the underlying cause of vertigo. Different types require different treatments. 2

• Do not continue benzodiazepines beyond the acute phase (>5 days), as this delays recovery and increases harm. 1, 4

• Do not use benzodiazepines as a substitute for canalith repositioning procedures in BPPV. The evidence shows repositioning has 78.6-93.3% improvement rates versus 30.8% with medication alone. 2

• Do not prescribe benzodiazepines concurrently with vestibular rehabilitation therapy. This combination is counterproductive. 1

Preferred Alternatives

• For BPPV: Canalith repositioning maneuvers (Epley, Semont) are first-line with 80% success rates. 2

• For severe nausea/vomiting: Prochlorperazine 5-10 mg is more appropriate than benzodiazepines. 1, 2

• For non-BPPV peripheral vertigo: Meclizine 25-100 mg as-needed (not scheduled) is preferred over benzodiazepines for most patients. 1, 2

• For long-term management: Vestibular rehabilitation therapy is more effective than prolonged medication use. 2
