Betahistine HCl 8mg/16mg is a medication primarily used to treat Ménière’s disease and other vestibular disorders that cause symptoms like vertigo, tinnitus (ringing in the ears), and hearing loss. Betahistine works by improving blood flow to the inner ear, which helps reduce the pressure that may cause these symptoms. It is believed to act by histamine receptors in the inner ear, improving microcirculation and reducing the buildup of fluid, which is a contributing factor to vertigo.

The medication comes in two strengths: 8mg and 16mg, and it is usually taken multiple times a day. Betahistine is typically prescribed for symptomatic relief, though it does not cure the underlying conditions but helps control the symptoms. It is generally well-tolerated but may have side effects such as headaches, nausea, or digestive upset in some patients.
