A patient with neuroleptic-induced lingual-facial-buccal dyskinesia and minimal drug-induced Parkinsonism was treated with Levodopa. This markedly worsened her abnormal movements. This observation supports the concept that tardive dyskinesias are related to hypersensitivity of dopaminergic receptors to dopamine. It is suggested that Levodopa should be avoided in such patients.
