Pharmacotherapy for visual hallucinations

Charles Bonnet syndrome (CBS) consists of vivid visual hallucinations which occur in otherwise psychologically normal people with insight. We reviewed the literature associated with pharmacotherapy for CBS. According to the limited data, antipsychotics such as risperidone, mood stabilizers such as valproate, antidepressants such as mirtazapine and Chinese medicine such as Yi-gan san are candidate treatments for visual hallucinations. Since existing data is solely derived from case reports, further controlled studies are required to establish pharmacotherapy for CBS.
