Nausea and vomiting can be common symptoms in the emergency department (ED). Antiemetics, agents to treat nausea and vomiting, include phenothiazine derivatives, prokinetic agents, and 5-HT3 antagonists. There have been limited studies on the use of these agents in the ED, and no direct comparisons to 5-HT3 antagonists have been published to date.
