Ondansetron for acute gastroenteritis in children
1Pediatric Research in Emergency Therapeutics, Hospital for Sick Children in Toronto, Ontario, Canada.
Insights
Ondansetron is not indicated for acute gastroenteritis in children. While it may be better tolerated than other antiemetics, evidence does not support reduced hospital admission rates.
Area of Science:
- Pediatric Gastroenterology
- Clinical Pharmacology
Background:
- Acute gastroenteritis is common in children.
- Parents frequently request antiemetic medications.
- Ondansetron is effective for chemotherapy-induced nausea and vomiting.
Purpose of the Study:
- To evaluate the role of ondansetron in managing acute gastroenteritis in children.
Main Methods:
- Review of existing evidence on ondansetron use in pediatric gastroenteritis.
- Comparison of ondansetron with other antiemetics.
Main Results:
- Ondansetron is not indicated for acute gastroenteritis.
- Evidence suggests ondansetron is well-tolerated with a favorable side effect profile.
- No evidence indicates ondansetron reduces hospital admission rates.
Conclusions:
- Antiemetic use is not standard for acute gastroenteritis.
- Ondansetron's use is at physician discretion.
- Potential adverse events must be considered prior to administration.
Question:
In my pediatric practice I see many children with acute gastroenteritis. Their parents ask for antiemetic medications. Ondansetron has been well tolerated when used to control nausea and vomiting in patients receiving chemotherapy. Is there a role for it in managing acute gastroenteritis in children?
Answer:
Use of antiemetics is not indicated for treatment of acute gastroenteritis. Some evidence suggests ondansetron is clinically more effective and better tolerated and has a better side effect profile than other antiemetics, but does not suggest that it reduces hospital admission rates. Use of ondansetron, as with other antiemetics, continues to be at treating physicians' discretion, and potential adverse events should be considered before administration.
