What is the first‑line treatment for benign paroxysmal positional vertigo (BPPV)?

First-Line Treatment for BPPV

Perform a canalith repositioning procedure (CRP) immediately upon diagnosis—specifically the Epley maneuver for posterior canal BPPV or the Gufoni/Barbecue Roll maneuver for horizontal canal BPPV—without ordering imaging, prescribing vestibular suppressant medications, or imposing post-procedural activity restrictions. 1, 2

Diagnostic Confirmation and Canal Identification

Before treatment, identify which semicircular canal is affected:

• Perform the Dix-Hallpike maneuver to diagnose posterior canal BPPV (85-95% of cases), looking for torsional upbeating nystagmus 1, 2
• If the Dix-Hallpike is negative but BPPV is suspected, perform the supine roll test to identify horizontal canal BPPV (10-15% of cases), observing for geotropic or apogeotropic horizontal nystagmus 1, 2

Treatment Algorithm by Canal Type

Posterior Canal BPPV (Most Common)

Execute the Epley maneuver immediately with the following steps 1, 2:

1. Patient sits upright with head turned 45° toward the affected ear
2. Rapidly lay patient back to supine head-hanging 20° position for 20-30 seconds
3. Turn head 90° toward the unaffected side and hold 20-30 seconds
4. Roll patient onto their side (nose pointing down) and hold 20-30 seconds
5. Return patient to sitting position

• Success rate: 80% after 1-3 treatments; 90-98% with repeat maneuvers if needed 1, 2
• Alternative: Semont (Liberatory) maneuver with 94.2% resolution at 6 months 1, 3, 4

Horizontal Canal BPPV

For geotropic variant (80% of horizontal canal cases):

• Gufoni maneuver (93% success rate): Move patient from sitting to side-lying on the unaffected side for 30 seconds, then quickly turn head 45-60° toward the ground and hold 1-2 minutes 1, 2
• Alternative: Barbecue Roll (Lempert) maneuver (50-100% success): Roll patient 360° through sequential positions, holding each for 15-30 seconds 1, 2

For apogeotropic variant (20% of horizontal canal cases):

• Modified Gufoni maneuver: Side-lying on the affected side, then head rotation toward ground 1, 2

Critical Post-Treatment Instructions

Patients can resume all normal activities immediately after successful repositioning 1, 2:

• Do NOT impose post-procedural head-position restrictions—strong evidence shows they provide no benefit and may cause unnecessary complications 1, 2
• Mild residual dizziness or postural instability lasting up to 24 hours is common and self-limiting 1

What NOT to Do: Common Pitfalls

Avoid vestibular suppressant medications (meclizine, antihistamines, benzodiazepines) as primary treatment 1, 2:

• No evidence of efficacy for definitive BPPV treatment 1
• Cause drowsiness, cognitive deficits, and increased fall risk (especially in elderly) 1
• Interfere with central vestibular compensation 1
• May only be considered for short-term management of severe nausea/vomiting in severely symptomatic patients 1

Do not order brain imaging or vestibular testing unless red-flag features are present (spontaneous nystagmus, direction-changing nystagmus, severe headache, neurological deficits) 1, 2

Do not delay treatment while awaiting test results or spontaneous resolution—this creates a high-risk period for falls 2, 5

Management of Treatment Failures

If symptoms persist after initial treatment, reassess within 1 month 1, 2:

• Repeat the diagnostic test (Dix-Hallpike or supine roll) to confirm persistent BPPV 1
• Repeat CRP achieves 90-98% success in persistent cases 1, 2
• Evaluate for canal conversion (occurs in 6-7% of cases) 1
• Consider multiple canal involvement or bilateral BPPV 1
• Rule out coexisting vestibular pathology if symptoms occur with general head movements 1
• Screen for CNS disorders if atypical features present (downward-beating nystagmus, direction-changing nystagmus without head position change) 1

Adjunctive Therapy and Fall Prevention

Assess fall risk before and after treatment 1, 2, 5:

• BPPV increases fall risk 12-fold, particularly in elderly patients 1, 5
• Evaluate for impaired mobility, CNS disorders, lack of home support 1, 2
• Provide home safety counseling and supervision recommendations 1, 5

Consider vestibular rehabilitation therapy (VRT) as adjunctive treatment 1, 2:

• Reduces recurrence rates by approximately 50% 1
• Particularly beneficial for patients with residual dizziness, postural instability, or heightened fall risk after successful CRP 1
• Not a substitute for CRP—should be offered in addition to, not instead of, repositioning maneuvers 1

Self-Treatment Option

Self-administered CRP can be taught to motivated patients after at least one properly performed in-office treatment 1:

• 64% improvement rate vs. 23% with self-administered Brandt-Daroff exercises 1
• Significantly more effective than Brandt-Daroff exercises (OR 12.38; 95% CI 4.32-35.47) 1

Special Populations Requiring Modified Approach

Assess for contraindications before performing standard maneuvers 1, 2:

• Severe cervical stenosis or radiculopathy
• Severe rheumatoid arthritis or ankylosing spondylitis
• Morbid obesity
• Significant vertebrobasilar insufficiency

For these patients, consider Brandt-Daroff exercises (though less effective: 24% vs. 71-74% success at 1 week) or referral to specialized vestibular physical therapy 1, 6
