Which antiemetic may be used as part of dehydration management?

• A. Ondansetron (Zofran)
• B. Prochlorperazine
• C. Promethazine
• D. Metoclopramide

Answer: (A)

Managing dehydration often hinges on allowing effective oral rehydration, and stopping vomiting is key to that. Ondansetron is a 5-HT3 receptor antagonist that works both in the brain and the gut to curb the vomiting reflex. It’s especially useful in gastroenteritis and in children because it reliably reduces nausea and vomiting without causing heavy sedation or extrapyramidal effects. Its oral forms make it easy to administer during rehydration, helping patients keep down fluids. Other antiemetics like dopamine antagonists can cause movement disorders, while promethazine tends to be sedating and carries notable safety concerns in kids. For these reasons, ondansetron is the preferred choice to support dehydration management by facilitating oral rehydration.
