What is the maximum total dose of Ondansetron within an 8-hour block?

Explanation:
Ondansetron is given in 4 mg doses with at least a 4-hour interval between doses. In an 8-hour window, you can administer two such doses, which totals 8 mg. This fits under the overall daily limit (about 24 mg per day) and follows the approved dosing interval. Higher totals would require more doses within the same 8 hours, which isn’t allowed due to the minimum 4-hour spacing. So the maximum total dose in 8 hours is 8 mg.
