Pediatricians determine the appropriate amount based on the child's weight, usually tailored to whether the child is under 15 kg, between 15 and 30 kg, or over 30 kg. 2. Chemotherapy-Induced Nausea & Vomiting (CINV) Dosing for chemotherapy is more frequent and depends on the child's age or weight. Children 4 to 11 Years: Oral administration occurs roughly 30 minutes before chemotherapy, with possible repeat doses 4 and 8 hours after the first dose, followed by maintenance doses for 1–2 days after treatment. Adolescents (12+ Years): Oral administration occurs roughly 30 minutes before chemotherapy, repeated 8 hours later, then maintenance doses for 1–2 days. Intravenous (IV) Option: IV administration occurs 30 minutes before chemotherapy, repeated 4 and 8 hours after the first dose, based on the child's weight. 3. Post-Operative Nausea & Vomiting (PONV) 1 Month to 12 Years: IV administration is typically weight-based for patients under 40 kg, or a set amount for those over 40 kg. 12 Years and Older: IV or intramuscular (IM) administration occurs before anesthesia or after the procedure.
