ALOXI demonstrated significantly greater complete response in the acute phase (81.0% vs 68.6%, p=0.0085) and in the delayed phase (74.1% vs 55.1%, p<0.001). Clinical superiority over other 5-HT3 receptor antagonists has not been adequately demonstrated in the acute phase.3,4       Important Safety Information (continued)       WARNINGS AND PRECAUTIONS       Hypersensitivity reactions, including anaphylaxis, have been reported with or without known hypersensitivity to other 5-HT3 receptor antagonists   Serotonin syndrome has been reported with 5-HT3 receptor antagonists alone, but particularly with the use of serotonergic drugs. Serotonin syndrome can be life threatening. Symptoms may include the following combination of signs and symptoms: mental status changes, autonomic instability, neuromuscular symptoms, seizures, and gastrointestinal symptoms. Patients should be monitored for the emergence of serotonin syndrome, and if symptoms occur, discontinue ALOXI and initiate supportive treatment. Patients should be informed of the increased risk of serotonin syndrome, especially if ALOXI is used concomitantly with other serotonergic drugs       ADVERSE REACTIONS       In adults, the most commonly reported adverse drug reactions include headache (9%) and constipation (5%)       For more information about ALOXI, please see Full Prescribing Information.       References: 1.
