20. General Treatment Principles
Medication for Acute Vertigo that lasts for few hours
to several days
Medications have various combinations of
acetylecholine, dopamineand histamine receptor
antagonism.
Benzodiazepines enhance GABA action ( GABA is
inhibitory neurotransmitter in vestibular system)
21. Strength of Recommendation
Key clinical recommendation
•The canalith repositioning procedure (Epley maneuver) is recommended in patients with benign paroxysmal
positional vertigo. A
•The modified Epley maneuver also is effective in patients with benign paroxysmal positional vertigo.B
•Vestibular suppressant medication is recommended for symptom relief in patients with acute vestibular
neuronitis. C
•Vestibular exercises are recommended for more rapid and complete vestibular compensation in patients with
acute vestibular neuronitis. B
•Treatment with a low-salt diet and diuretics is recommended for patients with Ménière's disease and vertigo.B
•Effective treatments for vertiginous migraine include migraine prophylaxis (e.g., tricyclic antidepressants, beta
blockers, calcium channel blockers), migraine-abortive medications (e.g., sumatriptan [Imitrex]), and vestibular
rehabilitation exercises B
•Selective serotonin reuptake inhibitors can relieve vertigo in patients with anxiety disorders. Because of side
effects, slow titration is recommended.B
A = consistent, good-quality patient-oriented evidence; B = inconsistent or limited-quality patient-oriented
evidence; C = consensus, disease-oriented evidence, usual practice, opinion, or case series. See page 1046 for
more information.
22. Medications
Meclizine* (Antivert) 12.5 to 50 mg orally every 4 to 8 hour
Dimenhydrinate* (Dramamine) 25 to 100 mg orally, IM, or IV every 4
to 8 hours
Diazepam (Valium) 2 to 10 mg orally or IV every 4 to 8 hours
Lorazepam (Ativan) 0.5 to 2 mg orally, IM, or IV every 4 to 8 hours
Metoclopramide (Reglan) 5 to 10 mg orally every 6 hours
5 to 10 mg by slow IV every 6 hours
Prochlorperazine (Compazine) 5 to 10 mg orally or IM every 6 to 8
hours
25 mg rectally every 12 hours
5 to 10 mg by slow IV over 2
minutes
Promethazine (Phenergan) 12.5 to 25 mg orally, IM, or rectally every
4 to 12 hours
23. Vestibular Rehabilitation
Exercises
These exercises train the brain to use alternative
visual and proprioceptive clues to maintain balance
and gait.
Improve postural control during the first month
after acute unilateral vestibular lesions resulting
from vestibular neuronitis.
24. Treatment of Specific Disorders
1- BPPV
(Usually posterior canal Calcium Debris)
MEDS..?
Head Rotation Maneuvers
Eply Maneuver
Contraindication: Severe carotid stenosis, unstable
heart disease, severe neck disease
Success rate: 80 % after one treatment, 100% with
repeated treatments.
Recurrence rates: 15% /year, 20% @ 20 months, and
37% @ 60 months.
25.
26. Treatment of specific Disorders
2- Vestibular Neuronitis
( Acute Prolonged Vertigo)
Symptom relief using vestibular suppressant
medications, followed by vestibular exercises.
Vestibular compensations occurs more rapidly and
more completely if the patient begins twice-daily
vestibular rehabilitation exercises soon after
symptom control with medications.
27. Treatment of specific disorders
3-Menier’s Disease
(Distension of Endolymphatic compartment due to
impaired endolymphatic filtration and excretion)
Low salt diet ( < 1-2 gm/day)
Diuretics ( combo HCTZ and Triamterene)
Surgery in rare cases - ablation of vestibular hair
cells)
28. 4- Vascular Ischemia
(Sudden onset of vertigo with additional symptoms eg
diplopia, ataxia, dysphagia, dysarthria)
TIA /Stroke: BP control, Cholesterol Lowering ,
smoking cessation, inhibition of platelet function,
anticoagulation
Vestibualr suppressant medications plus minimal
head maneuver on first day, then initiate
rehabilitation
Vestibular stents for symptomatic critical vertebral
artery stenosis.
30. 7- Psychiatric Disorders
( Anxiety , Panic disorders more common than depression;
Hyperventilation is the cause.)
Vesibular supressants and Benzodiazepines-
transient to inadequate relief.
SSRI show better relief.
Cognitive behaviour therapy may be helpful.
31. Physiologic Vertigo
Motion sickness: incongruence in the sensory
input from the vestibular, visual, and
somatosensory systems.Visual system does
not sense the movement.
Bring systems back in congruence! Eg watch
horizon when on a boat.also scopolamine
patch behind ear 4 hours before boating.
32. Disorder Duration Auditory Prevalence Peripheral or
symptoms central vertigo
Benign paroxysmal Seconds No Common Peripheral
positional vertigo
Perilymphatic fistula (head Seconds Yes Uncommon Peripheral
trauma, barotrauma)
Vascular Ischemia,TIA Seconds to hours Usualy not Uncommon Central or
peripheral
Meniere’s disease Hours yes Common Peripheral
Syphillis Hours yes Uncommon central
Vertiginous migraine Hours No Common Central
Labyrinthitis Days Yes Common Peripheral
Vascular Ischemia: Stroke Days Usually not Uncommon Central or
peripheral
Vestibular neuronitis Days No Common Peripheral
Anxiety disorder Variable Usually not Common Unspecified

Notas del editor
Leisions that progress slowly or processes that effect both vestibular appratuses equally usualy do not result in vertigo. Also Psychiatric disorders, Motionsickness, Serous OM, Cerumen imapction, HZ, Seizure disorders can also present with diziness.
Vertigo lasting for more than few days is suggestive of permanent vestibular injury ( eg Storke) and medications should be stopped to allow the brain to adopt to new vestibular input. 2- Older patients are at particular risks for side effects ( eg sedations , increased risk of falls, urinary retention., also drug interactions.
It is important for a patient to reexperience vertigo so that the brain can adapt to a new baseline of vestibualr funstion., after acute stablization, use of vestibular suppressant medications should be minimized to facilitate brain’s adaptation. RCT referance.
