How much Ondanestron (Zofran) do you administer to a casualty suffering from nausea or vomiting?

The appropriate dosage of Ondansetron (Zofran) for a casualty experiencing nausea or vomiting is 4mg. This dosage is commonly used in emergency and tactical settings to control nausea and vomiting due to various causes, including trauma, medication side effects, or other conditions.

Administering 4mg is effective because it strikes a balance between alleviating symptoms and minimizing potential side effects that could occur at higher doses. It is critical to adhere to recommended guidelines to ensure proper treatment while also maintaining the safety and wellbeing of the casualty.

Higher doses, such as 6mg or 8mg, may not be necessary in many situations and can increase the risk of side effects without providing additional benefit in symptom control. Therefore, 4mg is established as the standard initial dose in these scenarios.
