What is the maximum single dose of Zofran for adults experiencing nausea/vomiting?

Zofran, or ondansetron, is commonly used to treat nausea and vomiting, particularly in patients undergoing chemotherapy or surgery. The standard maximum single dose for adults is 8 mg. This dose is established based on clinical studies that effectively demonstrate the drug's safety and efficacy at this level. Administering more than this amount could lead to increased risk of side effects without significantly improving efficacy.

While lower doses, such as 4 mg, are also effective, they do not reach the recommended maximum threshold for optimal therapeutic effect in adults. It’s crucial for healthcare providers to adhere to these dosing guidelines to ensure patient safety and medication effectiveness.
