Summary
Betahistine is used to treat vertigo, which is a sensation of spinning or dizziness, and Meniere's disease, which is a disorder of the inner ear causing vertigo, tinnitus, and hearing loss.
Betahistine works by improving blood flow in the inner ear, which helps reduce symptoms of vertigo by balancing pressure and improving balance.
The usual starting dose for adults is 8 to 16 mg taken three times a day. It should be taken with food to reduce stomach upset. The maximum recommended dose is 48 mg per day.
Common side effects include nausea and headache, which are usually mild. If these symptoms persist, consult your doctor.
Betahistine should not be used by people with pheochromocytoma, which is a rare tumor of the adrenal gland. Caution is needed for those with asthma or a history of peptic ulcers.
