Aripiprazole-induced hiccups: a case report

Abstract

Hiccups can arise from idiopathic, psychogenic and organic causes. The use of therapeutic drugs forms one of the important causes of hiccups. Although the exact pathophysiological processes involved have not yet been established, the neurotransmitters dopamine, serotonin and gamma amino butyric aid (GABA) have been documented to play a significant role in the generation of hiccups. We report a patient of organic bipolar affective disorder who developed hiccups with the atypical antipsychotic aripiprazole. The possible underlying neurotransmitter mechanisms, predisposing factors and clinical implications of this rare adverse event are discussed.
