What is the maximum cumulative dose of Droperidol?

• A. 5 mg
• B. 10 mg
• C. 15 mg
• D. 20 mg

Answer: (B)

Droperidol can prolong the QT interval and trigger potentially life‑threatening heart rhythms, so clinicians cap the total amount a patient receives over a course. The upper limit typically cited is ten milligrams, allowing multiple small doses if needed while keeping cardiac safety in mind. A smaller total, like five milligrams, might be insufficient in some scenarios, whereas totals of fifteen or twenty milligrams exceed the safety threshold and raise the risk of QT-related complications. So, ten milligrams is the recognized maximum cumulative dose to balance effectiveness with safety.
