ondansetron dose adults children indications
GradeResponse
Ondansetron dosing depends on indication, age, route, and organ function.
From a clinical reference:
- Adults: 8 mg PO every 12 hours or 4 mg IV every 8 hours PRN
- Children: 0.15 mg/kg PO or IV every 12 hours, max 8 mg per dose
(Clinical Management and Infection Prevention and Control for Mpox, p.135)
Important safety note: ondansetron can prolong QT interval, so caution is needed in patients with long-QT risk or when combined with other QT-prolonging drugs.
If you want, I can give the exact dose for your scenario (for example: chemo, postop, gastroenteritis, pregnancy, adult vs child).
