Benzodiazepines for neuroleptic-induced tardive dyskinesia.

Tardive dyskinesia (TD) is a potentially disfiguring movement disorder of the orofacial region often caused by the use of neuroleptic drugs. A wide range of strategies have been used to help manage tardive dyskinesia and, for those who are unable to have their antipsychotic medication stopped or substantially changed, the benzodiazepine group of drugs has been suggested as a useful adjunctive treatment.
