A Common Fruit but Potentially Hidden Crisis: A Case Report of Betel Nut Intoxication.

This case involves a 41-year-old male experiencing agitation and confusion due to betel nut intoxication. The diagnosis was made by identifying the toxidrome through physical examination. Removing the residual betel nut with a finger and brushing it with water resulted in a significant improvement in consciousness and orientation within one hour. In addition to recognizing the toxidrome, prompt and effective treatment for the intoxicated patient is essential. Given the prevalence of betel nut chewing in Taiwan, emergency physicians should be particularly vigilant of arecoline toxicity.
