Rimegepant Effectively Treats Vestibular Migraine — Both Dizziness and Headache | Research

The takeaway

Rimegepant 75 mg demonstrates efficacy for acute vestibular migraine treatment, improving vertigo, unsteadiness, nausea, and headache symptoms in patients meeting VM diagnostic criteria.

All 5 VM symptoms improved
Rimegepant reduced vertigo, unsteadiness, nausea, sensory sensitivity, and headache

What the researchers found

Rimegepant 75 mg effectively treated acute vestibular migraine symptoms including vertigo, unsteadiness, nausea/vomiting, photo/phonophobia, and headache.

Why it matters

Vestibular migraine is the most common cause of episodic vertigo, affecting millions, yet has no FDA-approved treatment. Demonstrating rimegepant efficacy could change clinical practice.

How the study worked

Clinical study of rimegepant 75 mg for acute VM attacks; patients meeting VM/probable VM criteria; 5 symptom severity ratings (0-3 scale) at multiple time points.

What this study cannot tell us

Likely open-label without placebo control; sample size may be small; short-term acute treatment only; VM diagnostic criteria overlap makes patient selection challenging.

How to read the evidence

Clinical study — provides important efficacy data but may lack placebo control for definitive evidence.

When this study was published

Published in 2026, pioneering CGRP antagonist therapy specifically for vestibular migraine.

The bigger picture

This extends CGRP antagonist therapy from traditional migraine headache to vestibular migraine, suggesting CGRP plays a central role in both the pain and vestibular components of migraine.

Questions still open

Should rimegepant be studied in a larger placebo-controlled trial specifically for vestibular migraine?
Does preventive rimegepant use reduce vestibular migraine attack frequency?

Common questions

What is vestibular migraine?

Vestibular migraine causes episodes of vertigo (spinning), unsteadiness, and dizziness along with migraine symptoms. It's the most common cause of recurring vertigo and often goes undiagnosed.

Can rimegepant help with dizziness, not just headache?

Yes — this study shows rimegepant improved all vestibular migraine symptoms including vertigo and unsteadiness, not just headache pain. This suggests CGRP plays a role in the dizziness component of migraine as well.
