- Zofran (ondansetron) is generally safe to use for the treatment of nausea and vomiting. However, it can prolong the QT interval and increase the chance for torsades.
- Low doses of Zofran are not likely to be an issue. However, when multiple doses are given, especially in the setting of a preexisting LQTS, clinical concern should be raised.
- When giving Zofran to a patient with an increased risk for torsades, consider continuous cardiac monitoring or an alternate anti-emetic.
