If you get sudden dizzy spells, ringing in the ear, or that heavy, off-balance feeling, betahistine is one of the medicines doctors use to help. It is mainly prescribed for vertigo and Meniere's disease symptoms. Betahistine aims to reduce spinning sensations and improve balance so you can get back to daily life without constant motion sickness.
Betahistine is a histamine-like drug that works in the inner ear and brain to improve blood flow and reduce pressure inside the ear. Many people notice fewer attacks and less severe dizziness after starting treatment. But it usually takes time; expect several weeks before you can judge whether it helps you.
Common doses seen in clinical use are around 8 to 16 mg taken two or three times a day, which totals about 24 to 48 mg daily. Some treatment plans use a single daily tablet with extended schedules, but your prescriber will choose the exact dose based on your situation. Don’t change the dose or stop suddenly without talking to your doctor — sticking to the plan helps prevent return of symptoms.
People often ask how long to try it. If you start and see no improvement after a month or two, discuss alternatives with your clinician. Some patients benefit from continuing several months, while others need a different approach if vertigo persists.
Benefits can include fewer and shorter vertigo attacks, less nausea, and improved balance. Side effects are usually mild — headache, stomach upset, or mild skin reactions can happen. These often fade in a few days. If you get severe allergic reactions, intense stomach pain, or unusual bleeding, seek medical help right away.
There are a few practical cautions. If you take strong antihistamines for allergies, they might reduce betahistine's effect, so check with your doctor. Also tell your prescriber about other medicines, pregnancy or breastfeeding, and medical conditions you have. Some countries do not approve betahistine, so availability varies — your pharmacist can explain what brands or generics are on hand where you live.
Simple lifestyle steps help reduce vertigo too: sleep on a consistent schedule, avoid sudden head movements, reduce salt intake if your doctor suggests it, and limit alcohol and caffeine. Physical therapy and balance exercises can speed recovery when used with medication.
If vertigo is new, severe, or comes with fainting, slurred speech, or weakness, seek urgent care — those signs need immediate evaluation. For ongoing dizziness, bring notes on attack frequency, triggers, and what helps. That makes it easier for your clinician to decide if betahistine or another treatment is right for you.
