- Chemotherapy-induced nausea and vomiting8 mg is usually taken 30 minutes before the start of chemotherapy, followed by another 8 mg 8 hours later, and then 8 mg every 12 hours for up to 1-2 days after treatment.
- Radiation therapy-induced nausea and vomiting8 mg is typically taken 1-2 hours before radiation, with repeat doses every 8 hours as needed during the course of treatment.

For most adults, the drug is taken every 8 to 12 hours depending on whether it is being used for chemotherapy, radiation, or postoperative care.
