What is the adult dosage of Zofran for nausea/vomiting?

The adult dosage of Zofran for the treatment of nausea and vomiting is correctly stated as 4 mg administered IM or via slow IV or IO, with the option to repeat the dose in 10 minutes if necessary, up to a maximum total of 8 mg. This dosing schedule allows for effective management of symptoms while minimizing the risk of adverse effects. The initial dose of 4 mg is often sufficient for relief, but the ability to administer an additional dose after a brief interval provides flexibility for patient needs based on their response to the medication.

The importance of the slow administration is to reduce the risk of potential side effects, such as hypotension or prolonged QT interval, which may occur with rapid injection. This protocol reflects a balance between efficacy and safety in medications used for nausea and vomiting.
