Betahistine: a practical guide to treating vertigo

If sudden spinning attacks or constant imbalance are ruining your day, betahistine is a medicine worth knowing about. It's commonly used around the world to reduce vertigo attacks, ease dizziness and sometimes help with the ringing in your ears (tinnitus). This page tells you in plain language what betahistine does, how people take it, and simple safety tips.

How it works and common dosing

Betahistine works by improving blood flow and regulating signals in the inner ear, which often calms the abnormal messages that cause vertigo. Think of it as a way to quiet noisy balance signals so your brain doesn't get confused.

The usual starting dose is 8–16 mg taken three times a day. Some people need up to 48 mg per day under doctor supervision. It comes as oral tablets—take with food if your stomach protests. Don’t expect instant results: many people notice fewer or milder attacks after 2–4 weeks. If there’s no improvement after about three months, your clinician will reassess the plan.

Side effects, safety, and practical tips

Most people tolerate betahistine well. Common side effects are headache, mild nausea, and occasional stomach upset. Serious reactions are rare but possible. Avoid betahistine if you have a known pheochromocytoma (a rare adrenal tumor) or a proven allergy to the drug. Always tell your prescriber about other medical issues, especially stomach problems or heart conditions.

Some medicines that block histamine receptors (certain antihistamines) may reduce betahistine’s effect. Mention all prescription drugs, over‑the‑counter meds, and supplements at your appointment. If you are pregnant, breastfeeding, or planning pregnancy, discuss risks and benefits—guidance varies by country.

Practical tips that help:

• Keep a simple diary: note date, trigger, duration and severity of attacks. That shows progress objectively.
• Take doses at the same times each day; set alarms if needed.
• Combine medication with vestibular rehab exercises if your therapist recommends them—exercise can speed recovery.
• Reduce known triggers: cut back on salt, caffeine and alcohol if your doctor links them to attacks.
