Zofran Dosage for Children
Zofran® (ondansetron hydrochloride) is a prescription drug approved for preventing nausea and vomiting due to several causes. It is commonly used to prevent nausea and vomiting associated with chemotherapy, radiation therapy, and surgery.
Zofran has only been studied in children for chemotherapy-induced nausea and vomiting. For children, the oral solution (liquid) or orally disintegrating tablets (ODTs) may be especially useful (both are strawberry-flavored). The recommended dosage of Zofran for children varies, depending on your child's age.
- For children 12 years and older, the dose is the same as the adult dose.
- For children age 4 through 11, the dose is Zofran 4 mg three times daily. The first dose should be given 30 minutes before the start of chemotherapy. The second dose should be given four hours after the first dose, and the third dose should be given eight hours after the first dose. For one to two days after chemotherapy, Zofran 4 mg should be taken three times a day (about every eight hours).
