WASHINGTON -- A drug used to treat nausea and vomiting caused by chemotherapy may trigger dangerous and possibly lethal changes in heart rhythms, the FDA warned Thursday.
The drug, ondansetron (Zofran), may increase the risk of "developing prolongation of the QT interval of the electrocardiogram, which can lead to an abnormal and potentially fatal heart rhythm, including Torsade de Pointes," the FDA said.
