Betahistine
Betahistine may reduce recurrent vertigo associated with Ménière’s disease in some people. It does not treat every cause of dizziness, tinnitus or hearing change.
Key points
- New vertigo needs diagnosis because inner-ear, cardiovascular and neurological causes require different treatment.
- Asthma, stomach ulcer history and a possible catecholamine-secreting tumour require review before use.
- Sudden hearing loss, stroke signs, fainting or a new severe headache needs urgent assessment.
Listings are for comparison only. Suitability and supply depend on clinician and pharmacy checks, stock, destination rules and prescription requirements.
What Betahistine is used for
Betahistine may be used for recurrent vertigo with tinnitus or hearing loss when Ménière’s disease is the assessed cause.
How it works
Betahistine affects histamine receptors and may improve fluid dynamics and blood flow in the inner ear. Benefit varies and should be reviewed against symptom frequency and function.
Important safety checks
Asthma, peptic-ulcer history, low blood pressure, pregnancy and antihistamine use need review. Betahistine should not delay assessment of a first, severe or changing vertigo episode.
When to seek urgent care
Seek urgent help for facial droop, limb weakness, speech difficulty, new double vision, inability to stand, fainting, sudden hearing loss, a sudden severe headache or persistent vomiting with dehydration.
