Betahistine: What It Does and How to Use It

Betahistine is a medicine used to treat dizziness, vertigo and tinnitus linked to Meniere's disease. It helps reduce pressure and improve blood flow in the inner ear so you feel less spinning and nausea. Many people notice fewer attacks of vertigo after a few weeks of steady use.

You usually take betahistine by mouth. Doctors prescribe it in tablets with common doses from 8 mg to 24 mg, taken two or three times a day. Follow your doctor’s instructions — don’t stop suddenly if it works for you. Some users need several weeks to see clear improvement; steady daily use matters more than quick fixes.

How to take betahistine

Start with the lowest dose your doctor recommends. Take tablets with food to reduce stomach upset. If you miss a dose, take it when you remember unless it’s almost time for the next one — don’t double up. Keep a medication log or set alarms to keep doses consistent. If you have kidney or liver problems, your doctor may change your dose.

Avoid alcohol during treatment because it can make dizziness worse. Tell your doctor about other medicines you take — especially antihistamines, antidepressants, or drugs that affect blood pressure. Betahistine can interact with certain meds and health conditions, so full disclosure helps your doctor pick the safest plan.

Common side effects and precautions

Most people tolerate betahistine well. Mild side effects include headache, nausea, stomach pain, or indigestion. These often improve after a few days. Serious allergic reactions are rare but get medical help if you notice rash, swelling, or trouble breathing.

Betahistine is not recommended for people with pheochromocytoma or certain adrenal problems. If you have a history of peptic ulcers, mention that — your doctor will weigh risks and benefits. Pregnant or breastfeeding women should discuss options before starting betahistine.

Practical tips: keep regular follow-up visits so your doctor can track improvement and tweak the dose. Note patterns in a symptom diary — time of day, triggers, and severity — to share with your clinician. Combine medication with simple lifestyle moves: avoid sudden position changes, get up slowly from bed, sleep with the head slightly elevated, and reduce salt intake if recommended.

If vertigo suddenly worsens, you have new neurological symptoms (like sudden vision problems, slurred speech, or weakness), or symptoms don’t improve after a month, contact your healthcare provider right away.

Where to get betahistine: it’s a prescription medication in many countries. Use a licensed pharmacy or a trusted telehealth service to avoid counterfeit products. Compare prices if cost is a concern, and ask about generic options.

Common questions: Can betahistine cause drowsiness? Usually no, but some people feel tired or dizzy at first. How long to try it? Doctors often try betahistine for at least 4–8 weeks before judging benefit. Keep notes and ask for a review if you’re unsure. Be proactive, ask.
