Does betahistine actually work?
The evidence is genuinely mixed. It has been used across Europe for decades, but the largest UK trial found no benefit over placebo. It is well tolerated and reasonable to try — we will not pretend it is certain.
Will it help my dizziness?
Only if you have Ménière's disease. It does nothing for BPPV, vestibular migraine or light-headedness — and those are far more common.
How long before I know?
Two to three months, with an attack diary. Ménière's is so irregular that without a diary you genuinely cannot tell whether anything has changed.
Can I take it during an attack?
No — it is a preventer. Acute attacks are managed with a short course of something like prochlorperazine or cyclizine.
Does the low-salt advice matter?
It is long-standing advice, it is free, and it is worth a proper trial — spread evenly through the day rather than avoiding salt at one meal.
When is ear trouble an emergency?
Sudden hearing loss in one ear. That needs same-day assessment — steroids given within days can preserve hearing, and waiting loses it permanently.
Is it sedating?
No, unlike prochlorperazine and cinnarizine, which is why it suits long-term daily use.
