Olanzapine-induced hiccups： a case report / 四川精神卫生

ABSTRACT

The case report aims to raise the concern of clinicians about hiccups as an adverse reaction in olanzapine treatment. A 47-year-old male patient with epileptic mental disorder appeared symptoms of persistent hiccups on the fourth day of treatment with sodium valproate and carbamazepine jointing 10 mg/d olanzapine， and the symptoms disappeared two days after olanzapine withdrawal. The patient began to take olanzapine again， hiccups reappeared seven days after administration and relieved two days after withdrawal. During the whole treatment period， the dosage of sodium valproate and carbamazepine remained unchanged， indicating that the hiccups was induced by olanzapine. This case suggests that the possibility of hiccups should be considered in the clinical application of olanzapine.
