Nocturnal bruxism is a common oromandibular movement disorder highly prevalent in children, but its pathophysiological mechanism has not been fully explained. Iatrogenic sleep bruxism has been described following treatment with several psychotropic medications. However, no case of antihistamine-induced bruxism has been reported to date. Herein, we describe a 4-year-old child who experienced nocturnal bruxism during treatment for bronchospasm and rhinitis with the antihistamine ketotifen. Drug rechallenge was also performed. Conclusion: The present case adds useful information to our knowledge of bruxism. Complex and poorly understood interactions between multiple central nervous system neurotransmitters, such as histamine, serotonin, and dopamine, are involved.

Abstract
Nocturnal bruxism is a common oromandibular movement disorder highly prevalent in children, but its pathophysiological mechanism has not been fully explained. Iatrogenic sleep bruxism has been described following treatment with several psychotropic medications. However, no case of antihistamine-induced bruxism has been reported to date. Herein, we describe a 4-year-old child who experienced nocturnal bruxism during treatment for bronchospasm and rhinitis with the antihistamine ketotifen. Drug rechallenge was also performed. Conclusion: The present case adds useful information to our knowledge of bruxism. Complex and poorly understood interactions between multiple central nervous system neurotransmitters, such as histamine, serotonin, and dopamine, are involved.Pubblicazioni consigliate
