Olanzapine Induced Acute Meige’s Syndrome

Mrs. A, a 47-year-old married woman, fulfilled the DSM-IV criteria for paranoid schizophrenia. She had no family history of neurological and medical disorder. Her illness began when she was 44 years old. Her symptoms were characterized by persecutory delusion, withdrawn behavior, muttering to self, and decreased personal care. Childhood history and personal history did not reveal any symptoms suggestive of cerebral insult. She was initially treated with tablet trifluoperazine, 15 mg/day, but developed akathisia. Hence the trifluoperazine was replaced with clozapine, 200 mg/day. While being treated with clozapine for 8 weeks, Mrs. A developed sialorrhoea which disappeared after complete withdrawal of clozapine. She remained drug free for 6 months but she had a relapse of psychotic illness. This time, treatment with tablet olanzapine, 7.5 mg/day, was begun. On day 7 of olanzapine therapy, she exhibited both blepharospasm and oromandibular dystonia and had difficulty keeping both her eyes open. She also expressed her inability to speak and eat due to dystonic movements. Further, she was unable to perform vision-dependent tasks such as watching TV or cooking. The blepharospasm was exaggerated with stress, anxiety, and by looking upward. No abnormal movements were noticed in other parts of the body. Ophthalmological and neurological examination did not reveal any other significant findings. Olanzapine was discontinued and replaced by trihexyphenidyl, 4 mg, and clonazepam, 2 mg. Marked resolution of symptoms were noticed within 7 days after the withdrawal of olanzapine. There was no relapse of psychotic symptoms noticed for the next 6 months and she was maintained only on clonazepam, 1 mg/day.

Meige’s syndrome is one of the extrapyramidal syndromes that appears after long-term use of antipsychotic and it is believed that it is difficult to treat. 5 In this case, temporal relation between olanzapine administration, the appearance of characteristic dystonic reaction in the absence of choreoathetotic movements, and the prompt response to anticholinergic drugs can easily rule out idiopathic Meige’s syndrome. One might argue that that the remission of Meige’s syndrome was due to simple withdrawal of olanzapine and not because of the effect of trihexyphenidyl. This report suggests that Meige’s syndrome can occur even with atypical antipsychotics as an acute side effect and if diagnosed early, the withdrawal of causative neuroleptic can aid rapid recovery.
