Used primarily as an antiemetic to treat nausea and vomiting, especially in cases of gastroenteritis, morning sickness, and postoperative conditions. It works by blocking dopamine receptors in the chemoreceptor trigger zone of the central nervous system, helping to control the vomiting reflex. Commonly administered in oral, rectal, or injectable forms, it is often prescribed for short-term relief in both adults and children. Its effectiveness in managing mild to moderate nausea makes it a choice option in outpatient and clinical settings.
