                                Ondansetron + Escitalopram
                            
                        

                        
                        
Escitalopram and ondansetron together carry dual risks: serotonin syndrome and additive QT interval prolongation, making this combination particularly dangerous.

Azithromycin and ondansetron both prolong the cardiac QT interval; their combination substantially increases the risk of torsades de pointes.

Fluconazole inhibits the metabolism of ondansetron and both drugs prolong the QT interval, creating a compounded arrhythmia risk.

Ciprofloxacin and ondansetron both prolong the QT interval; combined use raises the risk of torsades de pointes and sudden cardiac death.

Hydroxychloroquine and ondansetron both prolong cardiac repolarization via hERG blockade; concurrent use substantially elevates arrhythmia risk.
