From the Guidelines

Meclizine is not recommended as a primary treatment for Benign Paroxysmal Positional Vertigo (BPPV) due to its lack of effectiveness in resolving the condition and potential for significant harm, including drowsiness, cognitive deficits, and increased risk of falls 1.

Key Points to Consider

  • Meclizine, an antihistamine, is often used to treat vertigo, dizziness, and motion sickness, but its use in BPPV is not supported by evidence as a definitive treatment 1.
  • The medication may provide short-term relief for autonomic symptoms such as nausea or vomiting in severely symptomatic patients, but it does not address the underlying cause of BPPV 1.
  • Repositioning maneuvers, such as the Epley maneuver, have been shown to be more effective in treating BPPV, with higher success rates and faster recovery times compared to medication alone 1.
  • The potential harms associated with meclizine and other vestibular suppressant medications, including increased risk of falls, cognitive deficits, and drowsiness, outweigh their benefits in the treatment of BPPV, especially in elderly patients or those taking multiple medications 1.

Clinical Decision Making

  • When considering the use of meclizine or any vestibular suppressant medication, clinicians should weigh the potential benefits against the risks, particularly in patients who are at higher risk of falls or have cognitive impairments 1.
  • Patients should be informed about the lack of evidence supporting the use of meclizine as a primary treatment for BPPV and the potential risks associated with its use 1.
  • Alternative treatments, such as repositioning maneuvers and vestibular rehabilitation, should be considered as first-line therapies for BPPV, with meclizine reserved for short-term management of severe autonomic symptoms if necessary 1.
