What is an appropriate prescription regimen for treating dizziness?

Model Prescription for Dizziness

For most cases of dizziness, medications should NOT be routinely prescribed, as the underlying cause typically requires non-pharmacological treatment (e.g., repositioning maneuvers for BPPV) rather than vestibular suppressants. 1, 2

When NOT to Prescribe Medications

Do not routinely prescribe vestibular suppressants (antihistamines or benzodiazepines) for dizziness/vertigo. 1, 2 These medications:

• Have no evidence of effectiveness as definitive treatment for BPPV (the most common cause of vertigo)
• Interfere with central compensation in peripheral vestibular conditions
• Increase fall risk, especially in elderly patients
• Cause drowsiness, cognitive deficits, and impaired driving ability
• Can decrease diagnostic sensitivity during examination

When Medications ARE Appropriate

1. Acute Severe Vertigo with Nausea/Vomiting (Short-term only - maximum 3 days)

For severely symptomatic patients requiring immediate symptom control:

Rx: Meclizine 25 mg

• Sig: Take 1 tablet by mouth every 6-8 hours as needed for severe vertigo
• Disp: #12 tablets
• Refills: 0

Alternative options:

• Dimenhydrinate 50 mg every 6-8 hours
• Promethazine 12.5-25 mg every 6-8 hours (for nausea)
• Ondansetron 4-8 mg every 8 hours (for nausea, fewer sedating effects)

For severe cases only:

• Diazepam 2-5 mg every 6-8 hours (maximum 3 days)
• Lorazepam 0.5-1 mg every 6-8 hours (maximum 3 days)

2. Ménière's Disease - Acute Attack Management

Rx: Meclizine 25 mg

• Sig: Take 1 tablet by mouth every 8 hours during vertigo attacks only
• Disp: #30 tablets
• Refills: 2

Plus prophylactic therapy:

Rx: Betahistine 16 mg (if available)

• Sig: Take 1 tablet by mouth three times daily
• Disp: #90 tablets
• Refills: 3

Rx: Hydrochlorothiazide 25 mg

• Sig: Take 1 tablet by mouth daily
• Disp: #30 tablets
• Refills: 3

Alternative diuretic combination:

• Furosemide 20 mg + Spironolactone 25 mg daily

3. Vestibular Migraine/Persistent Postural-Perceptual Dizziness

Rx: Propranolol 20 mg

• Sig: Take 1 tablet by mouth twice daily, may increase to 40 mg twice daily after 1 week
• Disp: #60 tablets
• Refills: 3

Alternative options:

• Topiramate 25 mg daily, titrate to 50-100 mg daily
• Venlafaxine 37.5 mg daily, titrate to 150 mg daily
• Sertraline 25 mg daily, titrate to 50-100 mg daily

Critical Caveats

• Always perform Dix-Hallpike maneuver first - if positive for BPPV, perform Epley maneuver instead of prescribing medication 2
• Reassess within 1 month to confirm symptom resolution or identify treatment failures 1
• Warn patients about fall risk - especially elderly patients on benzodiazepines or antihistamines 2
• Screen for cardiac causes - check orthostatic blood pressure before attributing dizziness to vestibular causes 8
• Consider central causes if symptoms persist despite appropriate treatment - 1-3% of presumed BPPV cases are actually CNS lesions 1

What to Avoid

• Prolonged use of vestibular suppressants (>3 days for acute symptoms)
• Routine prescription without proper diagnostic evaluation
• Benzodiazepines in elderly patients or those at fall risk
• Anticholinergics (scopolamine) except for motion sickness prevention
• Any vestibular suppressant as substitute for repositioning maneuvers in BPPV
