title: An elderly female patient with tardive oromandibular dystonia after prolonged use of the histamine analog betahistine.
abstract: Tardive oromandibular dystonia (OMD) is iatrogenic in origin and is characterised by orofacial and lingual stereotypes more frequently than the idiopathic form of OMD Tardive OMD is often associated with anti-dopaminergic treatment involving drugs such as anti-psychotics, anti-emetics, and anti-vertigo agents, although the syndrome can also be triggered by anti-epileptic or anti-depressant drugs that do not have anti-dopaminergic properties. We report an elderly female patient with OMD after prolonged, self-administered treatment with betahistine dihydrochloride, a histamine analogue.
