abstract
- Acute gastroenteritis is one of the most common causes of emergency room visits. Although it is usually a self-limited infection, vomiting related to this illness can cause various degrees of dehydration, leading to intravenous insertion, electrolyte abnormalities and/or hospital admission. Ondansetron is a highly potent antiemetic drug that is effective in preventing chemotherapy-and radiation-induced nausea and vomiting with a very low risk of adverse effects. Recently, ondansetron has been used to control vomiting related to acute gastroenteritis. The present article examines evidence for the use of oral ondansetron for acute gastroenteritis-related vomiting in infants and children, and provides a recommendation for treatment based on the evidence-based review.
