Description Ménière's disease is a progressive disease of the inner ear characterized by vertigo, tinnitus, and hearing loss. It has a significant impact on both the physical and social functioning of affected individuals.[A220318,L16408] Betahistine is a histamine-like antivertigo drug used for treating symptoms associated with Ménière's disease. It is thought to reduce symptoms through its actions on histamine receptors.[A220333,L16403] Betahistine was first approved by the FDA in the 1970s but withdrawn within approximately 5 years due to a lack of evidence supporting its efficacy. It is currently marketed in Canada by various companies, including Teva Pharmaceuticals.
Indications and Usage Betahistine is indicated for the reduction of recurrent vertigo episodes associated with Ménière's disease in patients 18 years old and above.[L16388]
