What is the initial treatment approach for a patient experiencing vertigo?

Initial Treatment Approach for Vertigo

The initial treatment for vertigo should be a canalith repositioning procedure (CRP) for patients with benign paroxysmal positional vertigo (BPPV), which is the most common cause of vertigo. 1

Diagnosis and Classification

Before initiating treatment, it's crucial to determine the type of vertigo:

• Triggered episodic vestibular syndrome: Vertigo provoked by positional changes relative to gravity (lying down, rolling over, bending down, tilting head back) suggests BPPV 1, 2
• Spontaneous episodic vestibular syndrome: Unprovoked episodes of vertigo may indicate Ménière's disease or vestibular migraine 2
• Acute vestibular syndrome: Sudden onset of persistent vertigo may suggest vestibular neuronitis/labyrinthitis 3, 4

Treatment Algorithm Based on Vertigo Type

For BPPV (most common cause)

1. First-line treatment: Canalith Repositioning Procedure (CRP) 1

   • For posterior canal BPPV: Epley or Semont maneuver
   • For lateral canal BPPV: Supine roll maneuver (Lempert)
   • Success rates reach 90-98% when repositioning maneuvers are performed correctly 1

2. Postprocedural care:

   • No postprocedural restrictions are necessary after CRP 1
   • Reassessment within 1 month to confirm symptom resolution 1

3. For treatment failures:

   • Repeat the Dix-Hallpike test to confirm persistent BPPV 1
   • Perform additional repositioning maneuvers if positive 1
   • Consider evaluation for other semicircular canal involvement or central causes 1

For Acute Vestibular Neuronitis/Labyrinthitis

1. Initial stabilizing measures 3, 4:

   • Position patient on their healthy side with head and trunk raised 20 degrees
   • Keep room quiet but not darkened

2. Pharmacological management (short-term only):

   • Vestibular suppressants: Meclizine 25-100 mg daily in divided doses 5
   • Anti-emetics for neurovegetative symptoms if needed 3

3. Follow with vestibular rehabilitation exercises once acute symptoms begin to resolve 2

For Ménière's Disease

• Low-salt diet and diuretics 4
• Consider vestibular rehabilitation 2

Important Considerations and Caveats

• Avoid routine use of vestibular suppressant medications (antihistamines, benzodiazepines) as first-line treatment for BPPV 1

• Neuroimaging is not recommended for typical BPPV with positive Dix-Hallpike test 1

• Warning signs requiring further evaluation 1:

  • Atypical or refractory symptoms
  • Associated auditory or neurological symptoms
  • Treatment failure after 2-3 repositioning maneuvers
  • Central nystagmus patterns (nystagmus that doesn't lessen with visual fixation) 6

• Pharmacotherapy limitations: While medications like meclizine can help manage symptoms in acute vestibular disorders, they are primarily for symptom reduction rather than cure 2

• Common pitfall: Failing to distinguish between peripheral and central causes of vertigo, which is critical for proper management 6, 7

Follow-up

• All patients should be reassessed within 1 month after initial treatment 1
• Persistent symptoms require evaluation for unresolved BPPV or underlying vestibular/CNS disorders 1
• Patient education regarding safety, potential for recurrence, and importance of follow-up is essential 1
